Pulmonary function tests were performed on 40 patients with neuromuscular disease. The maximum expiratory pressure was the most sensitive indicator of weakness and was decreased in 87% of adult patients. A comparison of Stead-Wells, electronic (Vanguard), and bellows spirometry (Vitalor) indicated an excellent correlation between the Stead-Wells and electronic devices. The bellows spirometer consistently underestimated volumes, particularly in severely weak patients.
对40例神经肌肉疾病患者进行了肺功能测试。最大呼气压力是肌无力最敏感的指标，87%的成年患者该指标降低。对Stead-Wells肺活量计、电子肺活量计（Vanguard）和波纹管肺活量计（Vitalor）进行比较，结果显示Stead-Wells肺活量计与电子设备之间具有良好的相关性。波纹管肺活量计始终低估了肺容积，尤其是在肌无力严重的患者中。
