Two patients with pneumothorax had ventilation-perfusion studies to rule out the possibility of pulmonary embolism; the presence of air in the pleural space was not known to the authors when the study was analyzed. A typical ventilatory pattern characterized by small volume difference at total lung capacity followed by disproportionately greater decrease of the volume of the affected lung at tidal breathing was observed. In one case, the routine chest radiograph failed to demonstrate air in the pleural space. A similar volume difference between the two lungs was noted on the perfusion images.
两名气胸患者进行了通气-灌注研究以排除肺栓塞的可能性；在分析研究时，作者尚不知道胸膜腔内存在气体。观察到一种典型的通气模式，其特征为肺总量时容积差异小，随后在潮式呼吸时患侧肺容积下降不成比例地更大。在一例中，常规胸部X线片未能显示胸膜腔内有气体。在灌注图像上也注意到两肺之间存在类似的容积差异。
