本文对101例慢性阻塞性通气障碍的患者作胸部X线片与肺功能测定的对比研究。胸片观察1.过度充气征,包括横膈位置(右顶部如在第Ⅶ肋骨前端水平或以下为下降,右顶部最大曲度少于1.5厘米为低平),及侧位胸骨后间隙之大小。2.肺泡破坏征象(肺小血管影象减少或消失)。3.肺动脉高压征(心脏和肺大血管扩大)。肺功能测定包括第1秒用力呼气量(FEV_1;相当第1秒时间肺活量绝对值)和肺活量、用重复呼吸法测定混合静脉血CO_2分压、弥散功能以及肺总量之测定和计算。将胸片所见的异常结果与肺功能改变对比,发现二者间有一定关系。横膈下降或胸骨后间隙达4.5
In this paper, 101 patients with chronic obstructive ventilatory failure in patients with chest X-ray film and lung function comparison study. Chest radiography 1. Inflation, including the location of the diaphragm (right top of the ribs at the level of the front or below the level of VII or below, the maximum curvature of the right top of less than 1.5 cm for the low level), and the size of the lateral space after the sternum . 2. signs of alveolar destruction (pulmonary vascular image reduction or disappearance). 3. Pulmonary hypertension sign (heart and lung enlargement). Pulmonary function tests included forced expiratory volume at 1 second (FEV 1; absolute vital capacity at 1 second) and vital capacity, and determination of CO 2 partial pressure, diffusive function and total lung volume with repeated respiration. Abnormal results seen in the chest and lung function changes found that there is a certain relationship between the two. Diaphragmatic decline or sternal space up to 4.5
