A rebreathing method for measuring carbon monoxide diffusing capacity is described. The method can be used in patients whose vital capacity is too small, or whose cooperation is inadequate, for the single-breath method. The apparatus is simple and the same gas mixtures are used as for the single-breath method. The results obtained by the rebreathing method are similar to those by the single-breath method (80% of the results by the rebreathing method lie within 20% of the value by the single-breath method). The rebreathing method also provides a measurement of the functional residual capacity.
本文描述了一种用于测量一氧化碳弥散能力的重复呼吸法。对于肺活量过小或无法配合单呼吸法的患者，该方法可用。该设备简单，且使用与单呼吸法相同的气体混合物。重复呼吸法得到的结果与单呼吸法相似（重复呼吸法80%的结果在单呼吸法结果的20%范围内）。重复呼吸法还可测量功能残气量。
