WellO2 is a respiratory training device that can be used to prevent respiratory infections or treat symptoms through home exercises. The WellO2 device does not treat the disease and is not a medical device.
During a viral epidemic that causes respiratory infections, breathing exercises with the WellO2 device may be beneficial prophylactically or during infection. Early breathing training strengthens the respiratory muscles, improves lung ventilation, and may prevent the onset or worsening of a possible lung infection. Inhalation of warm water vapor can improve the defense mechanisms of the airway mucosa against viral infections and reduce cough irritation.
The effects of the use of the WellO2 device on the respiratory system are based on counter-pressure breathing and the inhalation of warm water vapor. Exhalation against pressure opens the airways and warm water vapor on inhalation moisturizes the airway mucous membranes and facilitates clearing mucus from the airways. Regular counter-pressure breathing strengthens the respiratory muscles such as the upper respiratory muscles, diaphragm, abdominal and intercostal muscles, and thus helps to better withstand situations where the respiratory system is exposed to stressful conditions.
Respiratory training with the WellO2 device during mild respiratory infections is usually very safe. If breathing becomes very difficult, respiratory training with the WellO2 or any physical exercise should be avoided. Also, need for the medical care should be considered. However, light training with the WellO2 device can be of significant benefit in the fever-free recovery phase of an acute lung infection.
Respiratory muscle training relieves breathing difficulties and has sedative effects. Tranquil moment with the respiratory training activates vagal nerve and calms the anxiety caused by the illness.
The WellO2 device has a sanitation program that destroys any viruses, bacteria and microbes that may have entered the device with the help of hot steam. In the sanitation program, the mouthpieces and other loose parts of the device can also be cleaned inside the device.
The WellO2 device has an inbuild cleaning program which heats the device and its parts to almost 100 C. This helps to keep the device and its parts hygienic.
If you have no symptoms of a respiratory infection
You can use the WellO2 normally on a daily basis.
- Mucosa on the upper respiratory tract is the body’s first line of defense. Impaired mucous membranes open pathogens a way to our bodies. Functioning and intact mucous membranes help resisting respiratory infection. Moisturizing the airways with the steam restores humidity and activates cilia function, thus assisting clearing mucus and impurities from the airways. This will help keep your airways in good condition.
- Regular training with the WellO2 device strengthens the respiratory muscles and keeps the airways open. This helps the body to withstand the strain caused by respiratory infections.
- If you suffer from accumulation of mucus, WellO2 helps remove mucus from the airways. The pressure gradient in airways caused by the counter-pressure breathing and concomitant effect of the steam drives mucus out of the airways. Inoperative mucus transport exposes airways to infections.
- The use of nasal mask is important in the prevention of diseases! Viruses that cause respiratory infections usually enter our bodies through the upper respiratory tract, i.e. the nose or mouth, and warm moist air may reduce the growth of viruses in the upper respiratory tract and prevent the disease from progressing in our body.
If you have a mild symptomatic respiratory infection
The use of a WellO2 device is recommended on early onset of the infection with the minimum (0) counter-pressure setting.
- The use of a nasal mask is important! Infection route of the respiratory viruses is commonly a nasal cavity and larynx. Exposing mucous membranes in these infection routes with warm and humid air may impair replication of some viruses and prevent from extensive viremia.
- Some respiratory infections cause extensive accumulation of mucus in airways restricting airflow. Draining the airways from the accumulated mucus with the WellO2 allows better airflow and lighter breathing.
- During the infection, strenuous exercise of the respiratory muscles should be avoided. Use only a 0.
- It is important to use the device's sanitation program after each use when you suffer from any infections.
If you have a severe respiratory infection
- When your breathing becomes very difficult, contact your doctor.
- Do not perform training with WellO2.
Recovery after respiratory infection
- After discharging from the hospital or after otherwise severe respiratory infection when you are feverless, you may use the WellO2 device normally to restore breathing functions.
- However, before starting the breathing training consultation of your physician is recommended. At this point, the device should only be operated with the lowest 0 resistance.
- During the rehabilitation phase, training should be regular i.e. 2-6 times a day (gradually increasing the workload and avoiding excessive exertion) and it should continue for a sufficient period i.e. 6-8 weeks.
When not to use the WellO2 device
Do not use the WellO2 device if you have:
- pneumothorx
- pulmonary embolism (pulmonary embolism)
- recent myocardial and pulmonary infarction
- tympanic membrane damage
- fresh surgery or traumatic wounds on the face, chest, or abdomen.
Talk to your doctor about using the device if you have:
- asthma exacerbation
- acute febrile respiratory infection
- unexplained respiratory disease
- final pregnancy
- tendency to epistaxis
- severe heart disease
- arterial bulge (arterial aneurysm)
- very high blood pressure
