RESUMO
Objective To provide the oxygen supply apparatus when the civil aviator and airforce pilot are inspected the hypoxia tolerance and altitude tolerance in the hypobaric environment.Methods Demand oxygen and contstant flow oxygen were supplied.Results The portable hypobaric oxygen supply apparatus can supply mixed oxygen below the altitude 8 000 m,and the oxygenous concentration of mixed oxygen was adjusted according to the altitude.The pure oxygen was supplied when the altitude was at 8 000～12 000 m.Conclusion The normal and emergency oxygen supply performance can fulfill the system physiological requirements.The portable hypobaric oxygen supply apparatus may be used by the persons engaging in special task on plateau also.
RESUMO
This paper is to study the feasibility of Chinese female pilot to fly fighterplane considering their physiological and biochemical tolerability to altitude anoxia. The altitude anorexia was simulated on the ground in female pilot and their electrocardiograph, heart rate, blood oxygen saturation, blood pressure, blood uric acid(BUA), blood lactic acid(BLA), creatine kinase(CK) and aspantic aminotransferase(AST) were measured before and after flying, and the results were compared with that in the male pilots. There was no difference in electrocardiograph, heart rate, blood saturation, blood pressure, Cr, CK, BUA and AST in both sexes, but the Hb level was higher in female pilots than that in male ones( P
