The respiratory activity of spontaneously breathing dogs undergoing surgery during halothane/nitrous oxide/oxygen or methoxyflurane/nitrous oxide/oxygen anaesthesia was studied using a spirometer system. Respiratory tidal and minute volumes were directly related to body-weight under methoxyflurane but under halothane anaesthesia only the tidal volumes could be correlated with body-weight. Periodic deep breaths were seen in about one-third of the animals anaesthetised with methoxyflurane but were seldom seen in animals under halothane anaesthesia. Physiological dead-space remained constant for each animal during anaesthesia.
使用肺活量计系统研究了在氟烷/氧化亚氮/氧气或甲氧氟烷/氧化亚氮/氧气麻醉下接受手术的自主呼吸犬的呼吸活动。在甲氧氟烷麻醉下，呼吸潮气量和分钟通气量与体重直接相关，但在氟烷麻醉下，只有潮气量与体重相关。在用甲氧氟烷麻醉的动物中，约三分之一出现周期性深呼吸，而在氟烷麻醉的动物中很少见。麻醉期间，每只动物的生理无效腔保持恒定。
