Pulmonary functions, breathing pattern and rhythmic oscillations of inspiratory time, expiratory time and tidal volume were studied by calculating autocorrelation functions and power spectral densities in patients with chronic obstructive pulmonary disease and respiratory insufficiency, in patients with cardiac valvular disease and in patients with liver disease at rest. Despite of the pathological results of pulmonary function tests the rhythmic oscillations of inspiratory time, expiratory time and tidal volume were present in all patients and they were intraindividually and interindividually different in the same way as in healthy man.
通过计算自相关函数和功率谱密度，对慢性阻塞性肺疾病合并呼吸功能不全患者、心脏瓣膜病患者和肝病患者静息时的肺功能、呼吸模式以及吸气时间、呼气时间和潮气量的节律性振荡进行了研究。尽管肺功能测试结果显示存在病理情况，但所有患者均存在吸气时间、呼气时间和潮气量的节律性振荡，并且这些振荡在个体内部和个体之间的差异方式与健康人相同。
