肺气肿患者胸部透视下可见到膈肌低平及活动幅度减弱,对诊断有一定帮助。为了进一步研究肺气肿患者的膈肌活动幅度与通气功能的关系及不同年龄性别的正常人活动范围,测定了180名正常人和80例肺气肿患者的膈肌活动幅度和肺通气功能,发现膈肌活动幅度与通气功能的减退相一致,对肺气肿的诊断及肺功能评价有一定帮助,简介如下。
Patients with emphysema under the chest fluoroscopy can see the low level and amplitude of activity weakened, have some help in the diagnosis. In order to further study the relationship between the amplitude of diaphragmatic muscle activity and ventilatory function in patients with emphysema and the range of motion of normal people of different age and sex, the amplitude of diaphragmatic muscle activity and pulmonary ventilation were measured in 180 normal subjects and 80 emphysematous patients. The range of activity is consistent with the decrease of ventilatory function, which is helpful for the diagnosis of pulmonary emphysema and evaluation of pulmonary function. The brief introduction is as follows.
