肺容量(TLC)及气道阻力(Raw)均为检测肺功能的重要指标,我们采用美国麦加菲公司生产的肺功能检测仪分别对20例正常对照、30例阻塞性通气功能障碍患者、15例限制性通气功能障碍患者采用胸腔体描仪测量TLC及Raw,同时根据呼吸频率的快慢:(1)浅快呼吸法:(2)平静呼吸法,分别得到各组TLC、Raw的指标,并对其进行比较观察,报告如下: 1 资料与方法 1.1 病例选择:20例正常对照选自本院职工,均无烟酒嗜好,无心肺功能疾患,平均年龄28.6±6.4岁;30例阻塞性通气功能障碍患者,肺功能均提示 Lung volume (TLC) and airway resistance (Raw) are important indicators of lung function testing, we use the United States Mecca Philippines company’s lung function detector were 20 cases of normal controls, 30 patients with obstructive ventilatory dysfunction, In the 15 patients with restrictive ventilatory dysfunction, TLC and Raw were measured by the thoracic body scanner. Meanwhile, according to the speed of the respiratory rate: (1) shallow and fast breathing method: (2) Calm breath method, And their comparative observation, the report is as follows: 1 Materials and Methods 1.1 Case Selection: 20 cases of normal controls were selected from our hospital workers, no alcohol and tobacco habit, no heart and lung function disorders, mean age 28.6 ± 6.4 years; 30 obstructive Ventilation dysfunction in patients with lung function are prompted
