在COMEX‘97珠穆朗玛峰手术中，8名受试者在减压舱内模拟海拔8848米的高度爬升至海拔8848米。在模拟海拔0m、5000m和8000m记录NPIF，并测量口腔最大吸气和呼气流量(OPIF、OPEF)。环境温度和湿度得到了控制。从海平面到8000米，NPIF平均+/-SD增加了16+/-12%，而OPIF增加了47+/-14%。净现值上升0.085+/-0.03L.S(-1)每公里(p
The present study investigated whether there are changes in nasal peak inspiratory flow (NPIF) during hypobaric hypoxia under controlled environmental conditions.During operation Everest III (COMEX '97), eight subjects ascended to a simulated altitude of 8,848 m in a hypobaric chamber. NPIF was recorded at simulated altitudes of 0 m, 5,000 m and 8,000 m. Oral peak inspiratory and expiratory flow (OPIF, OPEF) were also measured. Ambient air temperature and humidity were controlled.NPIF increased by a mean+/-SD of 16+/-12% from sea level to 8,000 m, whereas OPIF increased by 47+/-14%. NPIF rose by 0.085+/-0.03 L.s(-1) per kilometre of ascent (p
