近十余年来神经病学家和肺科学家对睡眠与呼吸之间的关系产生了巨大的兴趣.国外学者在正常睡眠结构和睡眠障碍的电生理学和神经生化学机制研究的基础上,通过采用多种测量和记录技术(包括阻抗呼吸描记、吸速度描记、呼吸容量描记、呼吸压力传感装置、主动脉压和肺动脉压测定、脑电图多波记录和血气分析等)来观察在正常睡眠中和睡眠障碍情况下的呼吸机能和血气状态的变化.在临床和实验室的观察中,发现一些病人在清醒状态下呼吸机能正常,但是,在睡眠时出现呼吸暂停,这一现象被一些学者称之为睡眠无呼吸综合征(Sleep apnea syndrome, SAS),围绕该综合征做了较多的研究工作,积累了一些资料.
In recent ten years, neurologists and lung scientists have a great interest in the relationship between sleep and respiration.Foreign scholars in the normal sleep structure and sleep disorders on the basis of the electrophysiological and neurobiochemical mechanisms, through the use of more Measurement and recording techniques, including impedance plethysmography, aspiration velocimetry, plethysmography, respiratory pressure sensing device, aortic pressure and pulmonary arterial pressure measurement, EEG multi-wave recording and blood gas analysis, And changes in ventilatory function and blood gas state in the case of sleep disorders, and in clinical and laboratory observations some patients were found to be ventilatory when awake, but apnea during sleep was observed by some scholars As a sleep apnea syndrome (SAS), more studies have been done around this syndrome and some data have been accumulated.
