Abstract:
Ventilatory volumes and respiratory flow rate during quiet and rapid respiration were measured in 480 healthy pilots of our Air Force. The mean values were: VE, 9.58?1.74 1/min; MVV, 154.69?19.48 l/min; PIFR, 23.56?4.60 l/min; and FPIFR, 182.388?29.95 l/min.Regression analysis showed that they correlated well with each other as well as with body surface area (BSA), age, sitting height etc. The regression. formulae are Y = 2.97398 + 3.74173X2 for VE, Y = 103.921-0.839956X1 + 44.4811X2 for MVV, Y = 20.2761+0.735782X4 for PIFR, and Y = 99.9757-0.69924X1+ 59.7506X2 for FPIFR, where X1 stands for age, X2 for BSA, and X4 for vital capacity.The above results should provide a valuable physiological basis for designing aircraft oxygen equipment,for laying down the standard of on-board oxygen supply, and for pulmonary functional tests in pilots.
