The residual volume can oscillatorily be estimated in an easy way with the help of diving-gas. The oscillatory unit, furnished with a sensor of density, serves as a quick helium-analyser. An overestimation of the residual volume can appear as a result of the high volatility of the used gas, an underestimation can result because of the non-registration of lung parts with entrapped air. Therefore a differentiated interpretation of the curve of wash-in is suggested. Thus a good conformity can be found with the body plethysmographic results also in patients with obstructive airways diseases including persons with disturbances of ventilatory distribution.
借助潜水用气体，可以轻松地以振荡方式估算残气量。配备密度传感器的振荡单元可用作快速氦分析仪。由于所用气体挥发性高，可能会高估残气量；由于未记录有滞留空气的肺部区域，可能会低估残气量。因此，建议对洗入曲线进行差异化解读。这样，在包括通气分布紊乱患者在内的阻塞性气道疾病患者中，也能发现与体容积描记法结果有良好的一致性。
