A mathematical model of atrioventricular chamber with varying partial pressure of alveolar oxygen during explosion decompression was set up and numerical simulation was carried out for the process of explosion and decompression under the condition of oxygen supply to the molecular sieve.The results of simulation and measured data are in good agreement.The height of flight, Oxygen concentration on the process.This model provides a simple method for solving the time when alveolar oxygen pressure drops to critical value during explosion decompression and is of practical significance to the design of medical monitoring and emergency oxygen supply equipment for high altitude flight.
