Functional residual capacity (FRC) was measured before and after induction of anaesthesia for jejunoileal bypass surgery in 30 morbidly obese patients. The onset of anaesthesia was associated with a 51% reduction in FRC from 2.2 litre to 1.0 litre. Eighteen of the patients were investigated more extensively; in these subjects FRC was reduced below the control values of residual volume (RV) with the onset of anaesthesia, but recovered towards baseline after laparotomy incision. Reduction in FRC is related to baseline vital capacity (VC) and FRC and is much greater than that reported for patients of normal weight.
对30例病态肥胖患者在空回肠旁路手术麻醉诱导前后测量功能残气量（FRC）。麻醉诱导使FRC从2.2升降至1.0升，降低了51%。对其中18例患者进行了更广泛的研究；在这些受试者中，麻醉诱导时FRC降至残气量（RV）的对照值以下，但剖腹手术切口后恢复至基线水平。FRC的降低与基线肺活量（VC）和FRC有关，且比正常体重患者的降幅大得多。
