Pulmonary function studies were performed within 72 hours of injury in seven patients with smoke inhalation injury diagnosed by positive 133Xe scintiphotographs and in eight patients with burns of similar size but with negative 133Xenon scans. The former patients showed decreased peak flow, decreased flow at 25, 50, and 75 per cent of vital capacity, and an elevated pulmonary resistance. In addition, single breath nitrogen tests revealed evidence of maldistribution of ventilation/perfusion abnormalities. Total lung capacity, functional residual capacity, and compliance (both dynamic and static) were similar in the two groups. Pulmonary function studies can be of assistance in evaluating smoke inhalation, estimating the severity, and following the course of patients with this disorder.
对7例经133Xe闪烁照相呈阳性确诊为烟雾吸入性损伤的患者以及8例烧伤面积相似但133氙扫描呈阴性的患者，在受伤后72小时内进行了肺功能研究。前一组患者表现出峰值流量降低、肺活量的25%、50%和75%时流量降低以及肺阻力升高。此外，单次呼吸氮试验显示有通气/灌注异常分布不均的证据。两组的肺总量、功能残气量和顺应性（动态和静态）相似。肺功能研究有助于评估烟雾吸入情况、估计病情严重程度以及跟踪该疾病患者的病程。
