We used a clinical score, the pulmonary index (PI), in the emergency room assessment of children with acute asthma. The PI was derived from respiratory rate, wheezing, inspiratory-expiratory ratio, and use of accessory muscles. Patients were treated with a beta-adrenergic drug and were assessed before and at 15-minute intervals after treatment using clinical examination, PI, and spirometry. The PI before treatment correlated significantly with the mean percent of forced expiratory volume in the first second to forced vital capacity ratio. The PI 30 minutes after treatment correlated significantly with all tests of pulmonary function performed. The PI is a simple score that is easily derived from clinical observation.
我们在对急性哮喘患儿的急诊评估中使用了一种临床评分——肺指数（PI）。PI源自呼吸频率、哮鸣音、吸气与呼气比值以及辅助呼吸肌的使用情况。患者接受了β-肾上腺素能药物治疗，并在治疗前以及治疗后每隔15分钟通过临床检查、PI和肺量计进行评估。治疗前的PI与第一秒用力呼气量占用力肺活量比值的平均百分比显著相关。治疗后30分钟的PI与所进行的所有肺功能测试均显著相关。PI是一种简单的评分，可轻松从临床观察中得出。
