COVID-19 patients may experience a sudden drop in oxygen levels (hypoxia) which can result in abnormal circulation and shortness of breath. However, some patients may suffer from extraordinarily low blood-oxygen levels, or hypoxia, without feeling short of breath. Patients compensate for the low oxygen in their blood by breathing faster and deeper — and this happens without their realizing it.
This silent hypoxia, progressing rapidly to respiratory failure, explains cases of Covid-19 patients dying suddenly after not feeling short of breath. Therefore, it is critical to monitor your oxygen levels during the pandemic.
The iFeelWell Smart Oximeter can help patients track their blood oxygen levels (SPO2), identify this silent hypoxia sooner and get a more effective treatment for COVID-19.
Heart rate variability (HRV) is a relatively new method for assessing the body’s reaction to sickness caused by bacteria and viruses and, in particular, the level of inflammation.
HRV is measured as the variability in the time gap between your heartbeats as you breathe in and out. This measure is influence by the Vagus nerve, responsible for controlling the changes in heartrate via the so-called parasympathetic or ‘rest and digest’ nervous system. The Vagus nerve also controls the body’s immune system reaction (via the cholinergic anti-inflammatory pathway), making HRV a critical measurement of our immune system strength.
Noticing a drop in HRV can give us an early warning of possible infection by Coronavirus.
iFeelWell’s pulse oximeter is a device that offers a reliable method for checking vitals such as blood oxygen levels (indicator of lung function), heart rate, circulation and heart rate variability (indictors of heart function). To medical professionals, this kind of data helps provide a quick assessment of a person’s current state of health.
Though access to these devices is often done by visiting a doctors’ office, iFeelWell’s pulse oximeter allows anyone to monitor that data from home as well. The iFeelWell oximeter comes with a companion smartphone application to chart readings on a daily, weekly, or monthly basis, and allow the user to transmit measured vitals to a doctor if needs be.
The coronavirus pandemic, which has killed more than 200,000 Americans and resulted in record unemployment, has made many understandably feel stressed and anxious. A Centers for Disease Control and Prevention survey found that 31 percent were experiencing symptoms of anxiety and depression, about three times the number recorded in 2019.
Research has shown that psychological stress is associated with an increased risk of acute infectious respiratory illness (David A.J. Tyrrell, M.D). Furthermore, “high levels of cortisol [stress hormone] are associated with poor [Covid-19] outcomes, and drugs that block the hormone seem to improve outcomes,” says Kavita Vedhara, a University of Nottingham professor of health psychology who is conducting an ongoing study into Covid-19 and stress. Vedhara says she wouldn’t be surprised if chronic stress was found to be a risk factor for a severe case of Covid-19. “It fits with what we know about psychological stress generally, and in particular the evidence on stress and other viral infections,” she added.
The iFeelWell stress relief app and iFellWell oximeter are designed to teach you simple but effective scientific personalized stress relief breathing exercises. iFeelWell’s relaxation exercises are driven by your heart rate (HRV) obtained by the iFeelWell smart oximeter, allowing the exercises to be specifically optimized for you. The HRV breathing exercises are fun and simple, helping you to harmonize your heart, mind and lungs. The HRV biofeedback breathing is a scientific, evidence-based solution showing:
HRV breathing exercises are used to enhance performance in IDF, NASA and Italy’s Olympic soccer teams
Incorporating iFeelWell into your daily life will reduce your stress, help you sleep better and relieve any tension, thereby potentially helping you to fight Covid-19.
Fifty years of research on stress suggests it has a profound effect on the body, influencing everything from memory to the way the body stores fat. It’s even been found to cause structural changes in the brain and to damage the DNA.
In general, “Chronic stress wears the body down,” says Kathryn Freeman Anderson, a sociology professor at the University of Houston. Over time, stress keeps the body locked into a heightened response, resulting in damage somewhat similar to an engine idling for too long. These effects have been shown to cause increase rate of respiratory infections including coronavirus (David A.J. Tyrrell, M.D).
Recent Neuro-Immunology research has shown how prolong stress brings the immune system to two extreme reactions. People with chronically high levels of stress have been shown to have elevates levels of inflammatory cytokines. On the other hand, chronic stress can reduce anti-viral immunity. High levels of cytokines have also been noted in severe cases of Covid-19, as have lower levels of lymphocytes, the white blood cells that help fight infections. An important bridge between the immune system and the brain is the vagus nerve, whose activity is measured by heart rate variability (HRV). The vagus informs the brain about inflammation and then inhibits it. Breathing exercise activate the Vagus nerve, which could inhibit inflammation.
iFeelWell solution is an HRV-biofeedback device which guides people to increase HRV as it is measured by the iFeelWell Smart Oximeter. High HRV shows that the nervous system is good at adapting to changes inside and outside of your body and it predicts longer survival from severe diseases like heart-disease and cancer. The higher your HRV, the better your body is at adapting to changes and stressors. When you’re overwhelmed by stress or are in bad shape due to lack of sleep, alcohol abuse, overtraining, or respiratory illness, your HRV begins to drop. This means your body is having trouble adapting to changes and maintaining homeostasis— a stable internal environment. It’s a signal you need to take measures and you can use iFeelWell HRV solution to regain that healthy balance.
