Pulmonary ventilation parameters (breathing depth, frequency and minute volume, and alveolar ventilation) of 5 healthy male test subjects who performed a 20-minute tilt test were analyzed. During tilt tests the above parameters showed oscillations in a range of about 1 minute. During the first 1-3 minutes of exposure the parameters exhibited an accentuated synchronization of the oscillations and the phenomenon of "general autonomic switch-over" with the negative phase (fall of the parameters under study below the baseline level after an initial increase above the baseline level). From the 4th minute till the 6.5th minute the function of individual components of the pulmonary ventilation system mismatched and the respiration efficacy fell. Thereafter this synchronization of the processes studied returned to the normal. Adequate adaptation of pulmonary ventilation to tilting developed not earlier than during the 13-14th minute.
对5名健康男性受试对象进行20分钟倾斜试验期间的肺通气参数(呼吸深度、频率、每分通气量和肺泡通气量)进行了分析。在倾斜试验期间,上述参数在约1分钟的范围内出现振荡。在暴露的最初1 - 3分钟内,参数表现出振荡的明显同步以及“全身自主转换”现象,即研究参数在初始高于基线水平后出现负相(低于基线水平)。从第4分钟到6.5分钟,肺通气系统各个组成部分的功能失调,呼吸效率下降。此后,所研究过程的这种同步恢复正常。肺通气对倾斜的充分适应直到第13 - 14分钟才开始形成。
