The method of rebreathing and its particular importance to the estimation of blood alcohol concentration (BAC) are described. A face mask with an accompanying valve chamber to which a collection bag was attached proved to meet the requirements arising from the physiological exchange processes in rebreathed air. Practical tests in the laboratory revealed excellent agreement between the values obtained by direct measurements of breath alcohol by means of an IR-Spectrophotometer and those from stored samples. The application of the method described is of particular importance in cases of unconscious and benumbed patients, of sleeping and uncooperative patients and those with collapsed veins suspected of heavy alcohol intoxication. It has been proven to be an essential aid in differential diagnosis since it allows instantaneous determination and continuous monitoring of the BAC-level which aids in the observation of the reduction of this level. This was demonstrated in practice with 9 patients at the alcohol emergency clinic in Mainz on the carnival "Rosenmontag".
描述了再呼吸法及其对估计血液酒精浓度（BAC）的特殊重要性。一个带有附连阀室的面罩，阀室上连接有收集袋，事实证明该面罩符合再呼吸空气中生理交换过程产生的要求。实验室中的实际测试表明，通过红外分光光度计直接测量呼出气体酒精所获得的值与储存样本所获得的值之间具有极好的一致性。所描述方法的应用在无意识和麻木的患者、睡眠和不合作的患者以及疑似重度酒精中毒且静脉塌陷的患者的情况下尤为重要。事实证明，它是鉴别诊断的重要辅助手段，因为它可以即时测定和持续监测BAC水平，有助于观察该水平的降低情况。在美因茨狂欢节“玫瑰星期一”的酒精急救诊所，对9名患者的实际操作证明了这一点。
