Abstract
During airflight, cabins are pressurised to 8000ft (2438m) leading to an effective FiO of 0.15. This leads to a fall in oxygen saturation in all passengers, and especially those with underlying lung disease. The hypoxic challenge test using a body plethysmograph can predict a need for supplemental oxygen during airflight, and the process is described.
摘要
在飞行过程中，机舱内的压力会被加压至 8000 英尺（2438 米），这导致有效 FiO 降至 0.15。这导致所有乘客的血氧饱和度下降，尤其是那些患有潜在肺部疾病的人。使用体描仪进行缺氧挑战测试可以预测飞行中对补充氧气的需求，并描述了这个过程。
