Gas mixture and its use as needed 'respiration of people with pressure drops in aircraft or during hyperventilation and method thereof.

摘要

The gas mixture is used to ensure the ventilation of people in aircraft when needed. Depending on the density level, it is composed of 7 ± 5% CO 2 at 15 000 ft altitude with an increase of up to 17 ± 5% CO 2 at 30 000 ft altitude to improve the bioavailability of oxygen in the body. Either the mixture is produced by adding to pure O 2 or by adding to a composed of a proportion of N 2 and a proportion of O 2 gas mixture. The method for ensuring the respiration of people in case of pressure drop or generally in hyperventilation is characterized by the fact that they are made available by Aufsetzmasken a continuously supplied gas mixture as described above. Finally, the invention relates to the use of such a gas mixture to ensure the ventilation of people with limited freedom of movement in case of need. As a result, the amount of oxygen required for aircraft can be reduced and flight routes can be laid directly over high terrain, for example route (2) instead of route (1).
