O2COMFORT - Comfortable Oxygen Therapy

The principle is simple: when in comfort mode, oxygen is delivered accurately during the first phase of the inhalation, which is the only phase that can be used for oxygen exchange in the capillaries of the lungs. The pneumatic system of the flowmeter doesn’t contain electronics or batteries and is triggered by the spontaneous breathing of the patient.

The continuous mode functions as a classical flowmeter.

Premium patient comfort
Traditional, continuous oxygen therapy causes dehydration of the nose and the upper-airway mucosa that can lead to irritation, crust formation, nose bleeds and headache. The comfort mode keeps the moisture balance in the nose intact what stops the unpleasant side-effects for the patient.

Lower infection risk
The comfort mode allows humid air back into the patient’s nose. The need to use a humidifier disappears and so does the risk of an infection due to bacterial growth inside the humidifier.

Optimal oxygen consumption
The comfort mode ensures less oxygen waste compared to the continuous therapy while maintaining the same level of oxygen saturation. Long-term studies in different wards of the hospital validated a reduced oxygen consumption between 33% and 75%.

Higher therapy loyalty
It’s simple logic: when oxygen therapy no longer causes dehydration and stops being annoying, this likely makes the patient more loyal to the treatment. This higher therapy loyalty raises its effectiveness and eventually enhances the healing process.

Automatic closing
Interrupting treatment is as easy as taking out the nasal cannula. Comfort mode automatically cuts the oxygen flow but keeps the initial setting. When the patient re-inserts the nasal cannula the appropriate oxygen flow simply restarts.

Plug and play
The O2COMFORT flowmeter is a robust device that requires no maintenance. This easy-to-use instrument fits every type of connector and is fully certified. The life span is at least 8 years.
