过去20年来,人们关心上呼吸道阻塞性疾病,这种关心是由于在这些领域内知道得太少的缘固。下面是以往实验研究的概要。(1)鼻和肺之间的观察:对病人的研究包括使用标准的身体体积描记器、阴极射线示波器、墨水喷射描记,和计算与描记系统。食管气球也被使用。对鼻中隔偏曲的病人,研究其呼吸气流的顺应性和阻抗值,当鼻阻塞时,鼻阻抗增 People have been concerned about obstructive airway disease over the past two decades, a concern that is due to the lack of knowledge in these areas. The following is a summary of previous experimental studies. (1) Observation of the nose and lungs: The study of the patient included the use of standard body plethysmographs, cathode ray oscilloscopes, ink jet tracing, and computational and tracing systems. Esophageal balloons are also used. Nasal septum deviation of the patient to study the respiratory airflow compliance and impedance values, when the nasal obstruction, increased nasal impedance
