WHAT IS OXYGEN THERAPY ?
Treatment by oxygen therapy may be necessary to compensate for a lack of oxygen.
The goal of oxygen therapy is to restore or maintain a constant rate of oxygen in the blood. Oxygen is a medical product that is prescribed by a physician, more generally by a pneumonologist.
The prescription must include 2 pieces of information:
- the oxygen flow (l/min), defined using the results of blood gases,
- the daily time duration (h/day).
The expected benefits are:
- decreased shortness of breath,
- a better tolerance of efforts required for daily activity (climbing stairs, etc.),
- a decrease in the number and duration of hospitalizations,
- improved sleep,
- improvement of general quality of life.
3 WAYS OF ADMINISTERING OXYGEN
- An oxygen concentrator
Also called an extractor, allows obtaining (from the ambient air) a gaseous mixture in which the oxygen concentration approaches 95 %.
- Liquid oxygen
A fixed tank containing a large quantity of oxygen in liquid form (-183°) allows regular filling of a light portable tank, and a high degree of autonomy; this type of device is intended for patients who walk for more than an hour a day.
- Gaseous oxygen
Several bottle sizes and capacities are available depending on the need to occasionally walk.
