Whereas studies in awake subjects have demonstrated that chest wall compliance (Ccw) is low in obese subjects, the one study performed on paralyzed obese subject found Ccw to be normal. The purpose of this study was to measure Ccw in awake obese subjects with the pulse-flow technique, a method which appears to detect respiratory muscle relaxation. Seven normal males, 14 obese males, and 8 obese females [body mass index (BMI) varied from 20 to 83 kg/m2] were studied in the seated position. Ccw was measured by blowing air at a constant flow into the mouth and lungs for approximately 2 s and calculated by dividing airflow in liters per second by the change in esophageal minus body surface pressure in centimeters of water per second. In normal and obese subjects we found no correlation between BMI and Ccw. We conclude that obesity does not decrease Ccw.
虽然对清醒受试者的研究表明肥胖受试者的胸壁顺应性（Ccw）较低，但一项针对麻痹肥胖受试者的研究发现Ccw正常。本研究的目的是使用脉冲流技术测量清醒肥胖受试者的Ccw，该方法似乎能检测呼吸肌松弛。对7名正常男性、14名肥胖男性和8名肥胖女性（体重指数[BMI]从20至83kg/m²不等）进行了坐位研究。通过以恒定流量向口腔和肺部吹气约2秒来测量Ccw，并通过将每秒升数的气流除以每秒食管压力减去体表压力变化的厘米水柱数来计算。在正常和肥胖受试者中，我们发现BMI与Ccw之间无相关性。我们得出结论，肥胖不会降低Ccw。
