Oxygen therapy is a medical treatment designed to bring oxygen to the body by the respiratory route. It can take place in a hospital (most often) or at home, in case of chronic problem (chronic respiratory failure).
Treatment with oxygen therapy is indicated in the following cases:
Additional oxygen is indicated here in adults when PpO2 (partial pressure of oxygen dissolved in arterial blood) is less than 60 mmHg (8 kPa) and / or AsO2 (arterial oxygen saturation) is lower at 90%.
High-level oxygen therapy (> 15 l / min) should be almost systematic in extra-hospital patients for life-threatening medical or surgical conditions, including in patients with chronic respiratory insufficiency.
The LTOT applies to patients suffering from chronic respiratory insufficiency (CRI) whose PpO2 is lower than or equal to 55 mmHg during several checks over several weeks, apart from a decompensation episode, under optimal medical treatment .
