Cyclic passive movements of the right arm at 1Hz induce an increase in pulmonary ventilation in man. This results from an increase in frequency of the respiratory cycles, mainly due to a shortening of the expiratory phase, and from an increase of the instantaneous flow. The delay between the beginning of the arm movements and the onset of the increase in flow is about 450msec.
右臂以1赫兹频率进行周期性被动运动可引起人体肺通气量增加。这是由于呼吸周期频率增加,主要是呼气期缩短所致,同时瞬时流量也增加。手臂运动开始与流量增加开始之间的延迟约为450毫秒。
