Method and apparatus for protecting the passengers of an airplane against hypoxia |
摘要 |
In order to protect the passengers of an airplane against the effects of depressurization of the cabin, breathing masks are fed with oxygen at a rate which is an increasing function of cabin altitude. Oxygen is fed via a constriction and an economizer bag, and an initial fraction only of the gases breathed out is caused to be re-breathed by collecting the initial fraction in a flexible re-breathing bag in communication with the mask. The re-breathing bag has a volume in inflated state which is not less than the total dead volume of the respiratory tract and the mask. A protective apparatus comprises a feed control unit supplying an adjustable flow rate to masks connected to a general pipe via respective economizer bags. A re-breathing bag retards re-breathing and stores only an initial fraction of the gases breathed out on each exhalation.
