在正常仰卧位人体上研究了呼吸机对呼吸模式和气体交换的影响。使用冠状系统，测量O2消耗，CO2产生，潮气量（VT），频率（f），每分钟通气量，平均吸气流量和吸气和呼气时间（TI和TE），并与使用面罩（m）和吸嘴加鼻夹（mp + nc）获得的数据进行比较。使用m或mp + nc分别导致VT增加32.5%和15.5%; f、TI和TE保持不变。由于TI没有变化，VT的增加完全是由吸气流量增加引起的。
Effects of ventilatory apparatus on breathing pattern and gas exchange were studied in normal supine human subjects. Using a canopy system, measurements of O2 consumption, CO2 production, tidal volume (VT), frequency (f), minute ventilation, mean inspiratory flow and inspiratory and expiratory time (TI and TE) were made and compared to data obtained with the use of a mask (m) and mouthpiece plus noseclip (mp + nc). Use of the m or mp + nc caused a 32.5 and 15.5% increase in VT, respectively; f, TI and TE remained unchanged. As TI did not change, the increase in VT was caused entirely by increased inspiratory flow.
