Bioresonance Wiki

Bioresonance is a core concept in the SIGNALIS universe, representing individuals’ ability to alter physical events with mere mental willpower alone – a phenomenon known as Synchronicity that allows physical phenomena that would otherwise only exist as coincidence to manifest into reality.

Bioresonance is a complementary medicine practice

Bioresonance therapy is an integrative healing practice that combines physical and emotional wellness. It works by balancing vibrational frequencies of living cells within the body to promote immune system health. Practitioners claim they can use this method to assist patients suffering from allergies, chronic pain and depression using Mora Nova devices which pick up electromagnetic frequencies emitted by bodies after an electronic inversion process and return them via electronic transmission back through to users; this allows practitioners to identify sources of imbalance within them so they may treat accordingly.

Bioresonance technology has been shown to effectively treat a wide range of ailments, ranging from allergies and digestive issues to chronic pain and migraines. It works on the theory that unhealthy cells emit altered electromagnetic waves due to DNA damage; then this machine attempts to balance out these frequencies by sending back balanced ones back into your body – effectively relieving symptoms associated with conditions like fibromyalgia and migraines, while managing symptoms associated with IBS or bloating disorders as well.

Many allergy sufferers find relief through this alternative medicine practice; however, its scientific validity remains limited. Most bioresonance research is small-scale while larger-scale clinical trials must take place before any definitive conclusions can be drawn regarding its efficacy; nonetheless, studies have yielded positive results in areas like allergy treatment and smoking cessation.

Franz Morell, widely considered to be the father of bioresonance therapy, invented its first treatment device using electrodes to scan electromagnetic fields on body. Once abnormalities were identified, electromagnetic frequencies from body were transmitted back through an electronic inversion process back into body via computer and then back again through electrical impulses. This laid the groundwork for modern-day bioresonance therapies which have become a mainstream part of medical care in Europe and other nations worldwide.

Recent research has demonstrated that bioresonance therapy can effectively treat depression in those suffering from recurrent depressive disorder, when compared with monotherapy using selective serotonin reuptake inhibitors, which is currently the standard of care for depression treatment.

Bioresonance devices

Bioresonance testing is an alternative diagnostic technique that measures subtle energy disturbances within your body’s electromagnetic field, such as food intolerances, toxic build-up or cell dysfunction. Scientists and therapists alike have recognized its safe, non-invasive diagnostic capabilities as an invaluable way of diagnosing your condition.

Every organ and system in your body emits electromagnetic signals that can be detected using bioresonance devices. Each cell produces unique frequencies that provide crucial insight into its health, which when disrupted due to illness, infection or stress can distort its natural balance – bioresonance therapy claims to correct such imbalances by sending counteracting frequencies that neutralize harmful signals and restore natural energy flow in the body.

BICOM(r) bioresonance device uses low-frequency electromagnetic fields to communicate with the body and detect any cellular disturbances. This information is then used to create personalized treatment plans. Once sent by the therapist to BICOM(r), vibrational patterns generated from BICOM(r) machines will then be returned back to patients as vibrational patterns. Therapists can then manipulate BICOM(r) machines for maximum therapeutic benefits.

Though scientific validation for this therapy remains limited, many individuals report positive results after receiving its treatments. Although placebo effects could play a part in any reported improvements, regulatory bodies and medical professionals remain wary as this technology has yet to undergo rigorous clinical studies which meet stringent scientific standards.

Researchers agree that bioresonance devices may help patients suffering from chronic illnesses to improve their health. Additionally, bioresonance may assist in monitoring cancer treatment effectiveness as well as managing allergies when severe or persistent. Bioresonance may also provide useful insight into finding out the underlying cause of allergies or any health conditions you are suffering from.

Bioresonance therapy

Bioresonance therapy is an alternative treatment method that utilizes a device known as the BICOM to analyze your body’s electromagnetic fields and identify any imbalances, then sends corrected frequencies back into your cells in order to restore healthy communication channels and promote healing, energy flow, and overall wellness. This therapy may be effective against conditions like allergies, depression, fibromyalgia, and digestive problems as well as allergies themselves.

Bioresonance technology operates under the assumption that each organ and cell in your body emits electromagnetic signals to communicate. When these frequencies are harmonious, your body runs efficiently; when these frequencies become imbalanced due to toxins, allergens or stressors disrupting them they lead to illness and disease. Bioresonance technology listens to electromagnetic whispers within our bodies in order to detect imbalances before symptoms manifest themselves.

Bioresonance sessions involve having electrodes placed on your skin by a practitioner. A machine will emit an electromagnetic frequency that travels through your body and returns back to the machine, helping therapists identify which frequencies have returned – this allows them to pinpoint where issues lie within your system so specific frequencies can be applied in order to cancel out negative frequencies and promote healing.

Owing to limited scientific research on this alternative approach to healthcare, many individuals report positive experiences from bioresonance therapy. It’s best to consult a trained practitioner first and ensure it fits with your existing health regimen before embarking on bioresonance treatment.

One study demonstrated the efficacy of bioresonance therapy to alleviate symptoms of depressive disorder among recurrent depressed patients – with results comparable to selective serotonin reuptake inhibitors (SSRI). Another investigation indicated its benefit in relieving chronic pain symptoms among fibromyalgia patients.

Bioresonance therapy utilizes a unique combination of signaling technology and natural biological communications between cells to stimulate them and accelerate healing processes within the body, such as allergies, digestive disorders or conditions such as fibromyalgia or arthritis. This therapy method has also proven useful in treating allergies.

Bioresonance in oncology

Bioresonance therapy can be an invaluable asset in aiding cancer patients overcome side effects from treatment, while improving quality of life by relieving symptoms such as pain, nausea and weakness. Furthermore, this noninvasive technique provides additional cancer recurrence prevention measures. Bioresonance is safe and noninvasive treatment option to complement traditional therapies.

BICOM Bioresonance device is an electronic amplifier which transmits harmonic frequencies back into a patient’s body in the form of harmonic vibrations, which are processed and inverted by specific areas for therapeutic use. The goal is to identify and remove resonant frequencies that cause imbalance and chronic disease from one or multiple regions within their bodies.

According to reports, many patients have experienced significant improvements in their symptoms after attending bioresonance therapy sessions, often comparable with results seen with traditional medical treatments. Furthermore, this noninvasive technique does not cause side effects and some even experienced complete cessation of symptoms altogether.

Numerous studies have confirmed the efficacy of bioresonance therapy for treating various disorders. One such research project by Dr. Schumacher involved 204 children suffering from various allergies; five to nine months post bioresonance treatment, most reported no allergy symptoms at all!

Another study revealed that bioresonance can cause synchronic events, or series of coincidences occurring together. This phenomenon can be explained by changes to chromatin conformation having electric oscillation capacity within the nucleus of cells – these changes may even be permanent and alter gene expression.

The Empress, who serves as the protagonist in SIGNALIS, had an extraordinary bioresonance connection to all corners of life and used this power to influence others beyond mere coincidences. Her ability to remotely create physical phenomena through thought is known as signalis; until recently it was not understood fully and often dismissed as mere chance.

Manifestation Paper Radionics Machine and Talisman Seals

The circles and lines of Abrams’ boxes evoke an old-curmudgeon’s-library aesthetic from early 20th-century New Age, yet unlike his machines they rely solely on intention for change instead of wires and metal to manifest it.

Energy Codes on this machine can help you manifest many different things – stress relief, restful sleep, increased creativity – just by placing your name or photo in spot 1 and the code number in spot 2. All it takes to use it effectively is placing them there!

What is Radionics?

Radionics, a noninvasive energy healing method developed by American physician Albert Abrams and known as pseudoscience due to a lack of scientific evidence, relies on subtle energies found both within matter and spirit to diagnose and treat conditions of various kinds. While many consider radionics to be useless or “quackish”, many individuals believe that it may help address physical, emotional, mental health concerns while increasing overall wellbeing.

Radionics treatment is founded on the idea that all living things possess an invisible energetic field which vitalises their physical bodies, and its goal is to keep this energy field functioning at peak condition. A trained practitioner can identify factors contributing to illness in people, animals, plants or soil and then administer therapeutic energies remotely in order to restore balance to those disturbed areas of energy flow. The entire process may even be accomplished remotely so as not to inconvenience patients in person.

Radionics practices employ radiesthesia – a specialised form of dowsing used to detect subtle vibrations of people, plants, animals and objects using pendulums or similar devices – as the foundation. Practitioners utilize these pendulums or devices with vibration detectors in order to’read’ these vibrations and determine what energy frequencies may need addressing through intuitive processes.

Once these frequencies have been identified, a radionics machine is configured to address them. A practitioner then works with rates, symbols or photographs to direct healing energy toward specific issues requiring attention. As these energies can travel through airwaves to reach remote locations without physical contact being necessary – making this approach accessible even without physically present treatment!

As with radiesthesia, radionics is an effective preventative medicine tool which can be used to maintain health or restore wellbeing. Many clients report feeling “lighter” or more center after an session as stagnant energy patterns begin to shift and shift more freely. Furthermore, as a complementary therapy radionics can support and augment conventional treatments for difficult to treat or chronic health issues.

How do Radionics Machines Work?

Abrams and his followers believed that all matter released electromagnetic vibrations which could be detected with special machines. He believed this energy could also be harnessed to heal patients, animals and plants as well as provide engineering solutions such as making tape more adhesive.

Radionics stands apart from most alternative medicine techniques in that it can be used remotely to treat someone. A healing factor (homeopathic remedy, rate suggested by de la Warr or Drown or anything that represents an energetic characteristic) is transferred from practitioner to patient through either physical meeting or witness sample such as photograph.

Devices have no inherent power; activating it requires the practitioner. That is why most users of such devices are doctors or associated with medicine; medical practitioners tend to utilize such devices when attending courses on dowsing or bioenergy therapy, with beautiful instruments often featuring antique aesthetics that give them a mysterious feel.

As far as their work goes, Laurie does not profess to know exactly how radionics works and warns against overstating its benefits. While no scientific proof exists for its efficacy, most users who utilize it still experience positive outcomes – something he attributes to radionics stimulating the body’s natural ability to heal itself while conveying practitioner intent.

With the paper version of radionics machine, all that’s necessary to create healing energy is placing a photo or name of someone to heal or an animal or situation you want to address in the square area on the left and then selecting from one of your pre-programmed energy codes in the spiral on the right. This directs healing energy in its intended direction.

What are the Benefits of Radionics Machines?

Radionics offers many benefits for individuals’ health. One major one is being able to connect and balance an individual’s energy field, enabling customized healing. Practitioners use physical representations like photos, blood samples, hair or handwriting samples as “witnesses,” with radionics purportedly working by retuning energy patterns – similar to how musical instruments may be tuned – until harmony has been restored in that energy pattern. Furthermore, conscious intent may amplify its effects even further.

Practitioners believe that balancing one’s energy field can help address the cause of illness rather than treating its symptoms alone, since all illnesses start with energetic disturbances and radionics can help clear away imbalances before they manifest physically in one’s body.

Many practitioners of radionics tout its mental and emotional health benefits, citing it to promote relaxation and clarity as well as helping with chronic conditions and supporting spiritual growth. Furthermore, radionics is sometimes used in agriculture to boost soil fertility while simultaneously managing pests and diseases.

Notably, though these benefits of radionics may be widely touted, there is limited scientific support to back them up. Thus, those interested in using radionics as part of conventional medical treatment and not as an independent wellness practice are advised to use it only if safe for themselves and to discuss any potential concerns with their physician beforehand.

How to Use Radionics Machines

If you have purchased this Manifestation Paper Radionics Machine and Talisman Seals subscription, then you can use it to attract things into your life such as people, places and money. While healing may also benefit from using this machine, its primary use lies in drawing new things into it.

Place your name or photo in spot 1 and an intention code (letter/number combination) in spot 2. An intention can also be run to bring peace, restful sleep or boost creativity – these might take several days before visible results manifest but they often do!

Step-by-Step Tutorials: Covers every aspect of building electric radionic devices, from wiring them with RF broadband amps to creating perfectly tuned Mobius cables.

Alternative Therapy Trailer

Alternative therapies are gaining popularity

Alternative therapies have become increasingly popular worldwide, especially within the US and its environs. A number of studies support using alternative therapies as pain management solutions; popular media coverage has promoted some such practices and some even recommended by medical practitioners; yet, their effectiveness remains highly controversial, and some therapies have even been known to cause side effects; it is essential for physicians to be informed about potential risks when prescribing alternative therapies.

Researchers conducted a recent study to gather information on individuals’ use of alternative medicine. Participants completed an extensive mail survey that covered topics like health beliefs and attitudes, views towards conventional medicine experiences, political beliefs and worldviews and more. Data were analyzed using multiple logistic regression model, with several predictor variables emerging as significant predictors of alternative medicine usage:

People with poorer health status tend to turn more often to alternative medicine as a source of treatment, perhaps as they’ve had less success treating their health issues using traditional medicine and have therefore sought other approaches. They could also be somatizers who attribute nonpathological symptoms as illness when there may be none present.

One factor that predicted alternative medicine usage was the number of health issues an individual reported experiencing, since this indicates they may treat each of their issues with various alternative remedies such as chiropractic, lifestyle diets, relaxation techniques and massage therapies. If they suffer from back problems for instance, alternative remedies could include chiropractic adjustments, lifestyle diets, relaxation techniques massage therapy psychotherapy – plus they could use these same techniques for anxiety chronic pain or urinary tract issues as well.

Predictor factors included education. This could be because those who prefer alternative medicine tend to read books and articles about alternative medicines more regularly and may have greater exposure. Furthermore, more educated people tend to be more skeptical of conventional medicine’s claims and techniques and more willing to question its techniques than people with lower educational attainment.

They are a form of holistic wellness

Alternative therapy refers to healing practices not typically considered part of conventional medicine. These therapies may be used either alongside traditional medical techniques or instead. Sometimes known as complementary medicines or natural healthcare practices, or holistic treatments; examples include acupuncture, yoga, meditation, herbal remedies and massages – these practices often stem from ancient traditions like Ayurvedic medicine in India or Traditional Chinese Medicine (TCM).

Many people turn to alternative treatments as an additional means of wellness care, as they provide a more holistic approach that emphasizes mind and body connection. Alternative remedies may also help individuals manage stress and anxiety which contributes to poor health conditions; although most methods used do not have scientific proof behind them they can still provide relief from chronic conditions while improving overall wellness.

Alternative therapies may provide people with opportunities to meet like-minded individuals and promote self-care practices that support longevity. Before engaging in any alternative therapy regimen, be sure to speak to your physician beforehand; they can tell if it’s safe and whether it could interfere with existing treatment plans.

Alternative therapies fall into five broad categories, encompassing nutritional, physiological, physical and mind-body approaches. Some therapies have proven their efficacy on mental health such as hypnosis, meditation and acupuncture; however, many practices don’t adhere to proper research protocols such as blind experiments and prior probability calculations.

Alternative therapies carry certain risks, including unqualified practitioners causing harm. Some therapies have not been sufficiently evaluated while others rely on theories which contradict scientific understandings of how the human body functions, while some even appeal to supernatural powers or invoke beliefs unproven by science. Furthermore, in certain instances a practitioner could administer a placebo or misdiagnose a patient causing serious injuries or even fatalities.

They are a form of therapy

Alternative therapies are non-traditional approaches that may be used alongside or in place of conventional medicine. They may include nutritional, physiological and physical approaches – yoga, acupuncture and Ayurveda are among the many examples; other methods may also involve meditation or hypnotherapy as mental health components.

Alternative practices often lack biological plausibility and do not meet the criteria for evidence-based medicine. Furthermore, many do not abide by proper research protocols like blind experiments or risk/benefit calculation resulting in invalid data. By comparison, modern medicine uses responsible and ethical clinical trials to test plausible treatments, providing repeatable evidence either of their effect or lack thereof.

Alternative practices may appear to work through various mechanisms, including placebo effects or misinterpreting the natural course of the condition or believing it is working; however, patients may actually suffer worse outcomes by opting for alternatives over their initial treatment plans; this phenomenon is known as therapeutic deception and has been studied widely.

They are a form of healing

Alternative therapies are nontraditional healing practices used in combination with or as an alternative to conventional medical approaches, including nutritional, physiological and physical techniques such as yoga, meditation, hypnotherapy and acupuncture. Many alternative therapies also have mental health benefits that boost emotional wellbeing and build resilience; however these methods should never replace seeing a licensed therapist for guidance or advice.

As opposed to modern medicines, which use scientific method trials to examine plausible therapies with ethical clinical trials, many alternative practices do not rely on evidence for plausibility, repeatability, or effectiveness – instead they may rely on testimonials, anecdotes, testimonials, faith traditions superstition beliefs supernatural “energies error in reasoning propaganda or fraud for their credibility.

No matter their widespread popularity, it’s essential to remember that alternative practices do not have any evidence of efficacy and may even be dangerous. While naturopathy and some forms of acupuncture fall under mainstream medicine categories, other alternative practices fall under complementary and alternative medicine (CAM). Studies show that people using CAM tend to avoid medical care, suffering more serious or life-threatening diseases as a result compared to those who don’t; this results in lost time, money, and the opportunity for effective treatments; additionally those engaging in unproven health practices risk falling prey to deception and fraud schemes as a result.

Energy Medicine For Eyes

Your eyes are an indicator of overall health. Many eye conditions are related to other issues and energy medicine can provide solutions for both.

Eat plenty of fruits and vegetables rich in Lutein and Zeaxanthin, two carotenoid compounds which are beneficial to eye health. Also incorporate omega 3s as they contribute to vision. Vitamin C also protects corneas against UV radiation.

1. Acupuncture

Acupuncture is an ancient healing art that works by manipulating the flow of energy (called “qi”) along the body’s 12 meridians, or channels. By stimulating certain points on these meridians, acupuncture boosts blood circulation while relieving pain, inflammation, or stress associated with eye conditions.

A 12-year-old girl experienced permanent macular damage caused by laser pen burn to her right eye, leading to poor vision, an unsightly spot/shadow in the center of her visual field, eye fatigue and other symptoms. Due to medical therapy’s potential side effects she was unwilling to undergo it; we suggested acupuncture therapy as a solution instead and she saw improvement after just one week of therapy; even her macular area improved from 0.25 to 1.0 on optical coherence tomography report!

Chinese medicine sees the eyes and optic nerve as inextricably interlinked; therefore, acupuncture can help balance and enhance energy flows around them, as well as promote blood circulation throughout the head and neck – essential factors when it comes to feeding your eyes and relieving eye strain.

Acupuncture has been shown to increase blood circulation, decrease eye inflammation and swelling, stimulate regeneration of optic nerve cells and treat chronic eye conditions like glaucoma more effectively than traditional treatments such as Chinese herbs, supplements and eye exercises alone. Recent trials have also supported its effectiveness for improving and maintaining eye health; some critics have even raised concern over these studies’ lack of controls, masking mechanisms or other features required for evidence-based assessments.

2. Acupressure

Acupressure uses pressure instead of needles to stimulate specific points (called acupoints) on the body in order to promote healing, with over 365 acupressure points located throughout your body and 200 of them specifically on ears.

Acupressure works on the concept that our bodies contain an intricate network of meridians that carry energy throughout. If these channels become blocked due to congestion or otherwise become stuck in its tracks, acupressure can help clear them so our body’s natural energy called Qi can flow more freely again.

There are numerous effective acupuncture points that support eye health. Jingming (UB-1) — which translates to “bright eyes” — is located in the inner corner of your eye and acts as one of the primary points to bring Qi and blood into the eyes for all kinds of eye issues such as early stage cataracts, glaucoma, night blindness and conjunctivitis. Furthermore, it serves as the crossing point between five channels: UB, LI, ST HT and yang qiao.

Other eye-healthy acupressure points include LI 4/He Gu, which should be applied on the outer corner of your eyebrow, for congestion and allergies; and SI 23/Qiuxian in the hollow below your eyebrow to treat redness, pain, swelling in supraorbital area as well as eyelid twitching. A licensed acupuncturist can demonstrate these points for patients; many acupressure techniques can easily be performed at home using guides from books or videos online.

Acupressure can be an effective and gentle form of healing, and can provide many people who are experiencing symptoms relief with its use. Before trying any new therapies during your cancer journey – traditional or alternative – it is wise to check in with your oncologist first – particularly if taking medications or have chronic health conditions which might be compromised by these therapies.

3. Massage

Similar to acupuncture, regular massage can also help alleviate eye strain by stimulating certain acupressure points believed to improve circulation and reduce stress around the eyes. Massage may even relieve twitching caused by computer use as well as headaches associated with it.

Massage also promotes restful sleep and enhances skin elasticity, as well as being used to treat depression and anxiety caused by muscle tension and poor circulation. Massage was once perceived as the domain of wealthy individuals or used for illegal activities – now however it’s widely offered at spas and health clubs alike! To get the most benefit out of massage it is wise to speak with the massage therapist first before beginning, particularly if taking prescribed medication or have medical conditions such as arthritis.

If you suffer from itchy, watery or red eyes, the acupressure point ‘Bambu Gathering’ could offer relief. Located under each eye’s outer corner and easily stimulated, this point can alleviate eye pain as well as watery or itchy eyes as well as tension headaches or mild migraines.

Another acupressure point to explore is ‘Chrysanthemum Clear Vision’ (Ju Hua), located beneath the eyebrows and directly in line with each pupil. Massaging this point may help reduce redness or swelling in your eyes as well as relieve tension headaches or assist in treating eye infections. Boiled chrysanthemum flowers may even help improve vision while alleviating any related ocular conditions – though please remember acupressure cannot treat diseases like glaucoma directly.

4. Meditation

Meditation techniques vary. Some involve concentrating on an object or mantra, while others can involve mindfulness and awareness of mental events. Meditation has numerous health benefits beyond stress reduction: it promotes greater peace of mind, increases self-concept, as well as helping improve eyesight function.

Meditation has many eye-health advantages due to its effect on circulation, increasing oxygen and nutrients to the eyes. Studies have revealed that during meditation sessions the heart rate slows, blood vessels dilate and circulation increases resulting in benefits to eye health.

Some individuals may find certain meditation techniques more useful in improving eye health than others; the best way to identify which techniques work is to try them all and select one that speaks to you.

If you don’t have much time for meditation, simple exercises can still benefit both your eye health and overall wellness. Deep breathing and visualisation techniques may help ease eye strain; additionally, experts suggest drinking eight-ten glasses of water each day and refraining from smoking or rubbing your eyes to reduce dry eye syndrome risk.

Staring into a candle flame is another useful eye-focused exercise. According to ancient texts like Gheranda Samhita and Chakrasamrutam, staring into its flame is believed to improve vision as it purifies the drishti – or space between eyebrows – which plays a crucial role in eye health and is associated with the yin meridian.

5. Energy Exercises

Your eyes are an indicator of overall health. Many diseases manifest themselves through eye problems, while vision issues may reveal systemic problems affecting your entire body. Acupuncture, energy medicine techniques and eating healthily may help restore proper functioning to your eyes.

Energy Medicine for the Eyes can dramatically enhance visual clarity and decrease frequency of eye and vision problems. Try including these energy exercises into your daily life:

Commence by massaging your eyebrows using the knuckles of your first fingers to gently and smoothly massage them, to activate Qi and increase energy circulation to your eyes, which helps alleviate eye fatigue while increasing vitality.

Step two is to place your hands over your face with the palms facing towards your eyes and activate the energy pathways directly surrounding them, envisioning them growing brighter until they expand into a ball of light before sinking it down into your belly, concentrating it there.

Eye and liver meridians are associated with the Wood Element. A strong Wood Element helps improve vision and eye health; therefore this six-minute routine aims to strengthen it and direct its energy towards eye care.

High Frequency Oxygen Therapy

HFNC provides warm, humidified oxygen up to 60 liters per minute through nasal prongs or cannula for delivery to patients. The oxygen/air blender enables precise titration of FiO2 independent of patient inspiratory flow rate, minimizing room air entrainment.

HFNC appears to reduce dyspnea intensity and work of breathing for adults with various underlying conditions, as well as decreasing respiratory support escalation needs compared to conventional therapy.

Improved Oxygenation

HFNC stands out from traditional oxygen delivery devices by providing warmed, humidified gas at flows up to 60 LPM with oxygen concentrations reaching 100%, giving clinicians greater precision when tailoring oxygen delivery for individual patients.

Studies on HFNC have demonstrated its effectiveness at improving oxygenation. Unfortunately, variations in inclusion criteria, device flow rates, FiO2 settings, duration and therapy duration make comparisons challenging and some studies used surrogate endpoints such as PaO2/FiO2 as opposed to clinically meaningful outcomes such as mortality or intubations for their analysis.

HFNC may contribute to oxygenation benefits by alveolar recruitment. A study on healthy subjects demonstrated this by showing how HFNC increased end-expiratory lung impedance and pressure, thus increasing oxygen recruitment into each alveolus. Improvement was more marked for supine than for prone lung, consistent with other interventions that target this mechanism of improvement.

Studies have demonstrated that HFNC improves oxygenation for patients with hypoxemic respiratory failure, without needing more intensive forms of therapy such as noninvasive ventilation (NIV) or mechanical ventilator support. One small study demonstrated this fact by employing HFNC on high risk intubation patients where its use significantly reduced episodes of severe desaturation during intubation procedures and shortened ICU stay times significantly.

Recent research comparing the pre-oxygenation efficacy of HFNC with NIV for patients undergoing bronchoscopy found that the former significantly enhanced oxygenation prior to laryngoscopy and prevented severe desaturations and hypoxemia during laryngoscopy procedures; additionally, its users experienced less discomfort than those receiving NIV.

Studies comparing high frequency noise cancellation (HFNC) therapy to standard oxygen therapy in cardiac surgery patients have also demonstrated its benefits, with one finding HFNC reduced the need for postoperative day 3 oxygen support escalation due to reduced respiratory drive; another study randomly assigned 340 cardiac surgery patients either 45 liters per minute of HFNC or 2-4 liters per minute conventional oxygen; both approaches yielded similar SpO2/FiO2 results.

Reduced Work of Breathing

High flow nasal prongs (HFNP) deliver heated and humidified medical gases at flows up to 60 liters per minute, producing physiological benefits beneficial in treating some forms of respiratory distress. Humidified oxygen delivery increases functional residual capacity, improves mucociliary clearance of secretions and lowers work of breathing; additionally it generates positive airway pressure which may recruit alveoli and lessen the need for noninvasive ventilation (NIV) or intubation.

High flow non-invasive ventilation creates an anatomical oxygen reservoir within the nasopharynx and oropharynx which reduces dead space. When oxygen is recycled back into upper airways through normal tidal volumes, CO2 retention occurs as a result, leading to ventilation-perfusion mismatch and increased CO2 retention in lungs. With high flow oxygen delivery systems like HFNC delivering volumes far exceeding respiratory metabolic demand volumes allowing improved gas exchange, reduced rebreathing CO2, and increased oxygen uptake.

Due to an increase in oxygen delivery, tidal volume (VT) remains constant while PaCO2 decreases with increasing HFNC flow. Therefore, this treatment could serve as an effective alternative to face mask therapy for patients unable to tolerate higher tidal volumes with conventional oxygen delivery methods.

Studies have demonstrated that high frequency nasal cannula (HFNC) can create positive expiratory pressures in the nasopharynx with mouth closed; however, its intensity varies with flow and patient posture and body habitus – this may prove difficult for infants who cannot comfortably tolerate HFNC as their oxygen therapy must increase accordingly.

Animal studies demonstrate that high frequency nasal cannula (HFNC) increases oxygenation while simultaneously decreasing breathing effort compared with conventional face mask oxygen delivery. Furthermore, HFNC is better tolerated than NIV and may provide a viable alternative for patients who do not meet criteria for more intensive therapy such as intubation. While more extensive clinical research needs to be completed to fully determine its full impact, this form of oxygen therapy should certainly be included as part of clinician’s therapeutic toolbox and considered when treating patients who do not meet criteria for more intensive therapy.

Reduced Intubation Risk

Intubation can be a high-risk procedure in patients with severe hypoxemia, and complications have occurred up to 40% of the time [49]. It is therefore vitally important that they are well pre-oxygenated prior to intubation; HFNC provides an effective means of pre-oxygenation as it does not interfere with laryngoscopy and nasal cannula delivery.

Utilization of HFNC to prevent intubation has been associated with reduced reintubation episodes, shorter ICU stays and an improvement in survival for intensive care unit (ICU) patients. Furthermore, using HFNC does not increase their risk for comorbidities or death in ICU patients.

HFNC has also been used for providing apneic oxygenation during tracheal intubation in patients with severe respiratory failure, and recent animal research demonstrated its ability to significantly delay severe desaturation during intubation compared with traditional face mask oxygen delivery methods.

A recent randomized controlled trial has demonstrated the benefits of high frequency noninvasive ventilation (HFNC) on ICU patients at lower risk, including less need for noninvasive positive pressure ventilation (NIPPV) and re-intubation; increased secretion clearance; reduced antibiotic need in those suffering sepsis; as well as decreased need for hospital readmission.

Another randomized controlled trial has demonstrated that early introduction of high-flow nasal cannulae (HFNC) therapy among ICU patients with hypoxemia was linked with decreased intubation rates and shorter hospital stays. 322 ICU patients with pre-extubation ROX index scores of 40 were randomly allocated either 20 L/min of HFNC therapy or conventional oxygen (1-5 L/min).

In another randomized trial, 30 LPM of HFNC was compared with NIV for use in intensive care unit patients meeting low-risk intubation criteria, and 49% versus 19% with NIV were able to avoid re-intubation without complications.

HFNC has also been proven to reduce re-intubation among lung transplant recipients and to improve survival, according to this study. Immunocompromised transplant recipients were randomly assigned either HFNC or conventional oxygen as a control treatment; with HFNC showing 29% less re-intubations compared with 45% in the control group and consequently better lung function, oxygenation, lower mortality rates and greater ventilator-free days at 90-day mortality reduction versus conventional oxygen alone.

More Comfortable

High frequency oxygen therapy has emerged as a non-invasive oxygenation support modality that has broad clinical application in the perioperative setting. It improves oxygenation, reduces WOB, enhances patient comfort, and extends the safe-apnoea window compared with conventional low-flow oxygen interfaces. It is a preferred oxygenation strategy during critical perioperative phases including pre-oxygenation and induction of general anesthesia, management of the anticipated or unanticipated difficult airway, sedation for endoscopic and upper airway procedures, tubeless microlaryngeal surgery, emergence and extubation. Furthermore, it is a superior oxygenation support modality in high-risk patients and special populations such as the obese, pregnant and pediatric population.

A key advantage of HFNC is its effective humidification and warming. This helps to clear secretions, decreases atelectasis, and prevents airway surface dehydration. This leads to enhanced patient tolerance and comfort compared with the use of conventional oxygenation interfaces such as face masks. It also enables more accurate delivery of oxygen to the target tissues while avoiding pulmonary hyperinflation and carbon dioxide desaturation.

Several studies have demonstrated superior oxygenation and patient tolerance with HFNC over low-flow oxygen delivered via face masks. A recent randomized trial of obese parturients undergoing cesarean delivery found that 3 min of HFNC significantly improved arterial PaO2 and lengthened the safe-apnoea period compared with face mask (FM) oxygenation, without altering minimum SpO2/EtCO2, nadir SpO2, or intubation success (51).

Another important clinical benefit of HFNC is its ability to sustain oxygenation during invasive procedures. In a study of pediatric patients requiring bronchoscopy, HFNC reduced moderate and severe desaturation episodes and procedure interruptions compared to low-flow oxygen (52). A similar finding was reported in a randomized trial of children undergoing glottic dilation for stenosis by bronchoscopy. HFNC maintained oxygenation, preserved respiratory stability and extended the safe-apnoea time compared with conventional oxygenation (61).

Despite these impressive benefits, HFNC should not be considered as a substitute for mechanical ventilation in severe hypoxaemic respiratory failure. However, it may be appropriate for patients with mild hypoxaemia or in whom there is a contraindication to the use of PEEP or a contraindication to nasal cannulas. Furthermore, it should be reserved for patients who cannot tolerate tracheal intubation and/or who require long periods of noninvasive oxygenation.
