A spectrum of clinical symptoms consisting of grey-out, black-out, and G-induced loss of consciousness has been identified in pilots of high performance aircraft. The M-1 maneuver used in conjunction with reclined seats and inflated G-suit provides significant protection against these symptoms. Centrifuge-trained United States Navy tactical aircraft pilots have recently reported a decreased ability to perform the M-1 maneuver while using the MBU-12P oxygen mask and CRU-79/P oxygen regulator. This report reviewed the performance specifications of these devices and compared them with published pulmonary flow rates. We found this oxygen system to interfere with the performance of the M-1 and other anti-G maneuvers. Further research is needed to characterize pulmonary flow rates during the performance of the M-1 maneuver in order to make recommendations for breathing system standards aboard high performance aircraft.
在高性能飞机飞行员中已发现一系列临床症状，包括昏厥、意识丧失和G力导致的意识丧失。与倾斜座椅和充气抗荷服配合使用的M-1动作可有效预防这些症状。最近，接受离心机训练的美国海军战术飞机飞行员报告称，在使用MBU-12P氧气面罩和CRU-79/P氧气调节器时，执行M-1动作的能力下降。本报告审查了这些设备的性能规格，并将其与已公布的肺流量进行了比较。我们发现该氧气系统会干扰M-1动作和其他抗G动作的执行。为了对高性能飞机上的呼吸系统标准提出建议，需要进一步研究以确定M-1动作执行过程中的肺流量特征。
