The role of respiratory muscles in acute changes of circulation and ventilation due to acetylcholine in anaesthetized spontaneously breathing rabbits was investigated. Significant increase of end-expiratory thoracic circumference and insignificant increase of abdominal one was found and was taken as a measure of changed respiratory muscles tone. The authors emphasize the important role of the respiratory muscles in the regulation of the thoracic and the abdominal volume. The increased lung volume is due to the action of the respiratory muscles of thorax and diaphragm. The abdominal muscles and diaphragm may regulate the abdominal volume and play important part in the redistribution of the blood.
研究了麻醉状态下自主呼吸的家兔中，呼吸肌在乙酰胆碱引起的循环和通气急性变化中的作用。发现呼气末胸围显著增加，而腹围增加不显著，并将其作为呼吸肌张力改变的指标。作者强调呼吸肌在调节胸腔和腹腔容积方面的重要作用。肺容积增加是由于胸廓和膈肌的呼吸肌作用。腹肌和膈肌可调节腹腔容积，并在血液重新分布中起重要作用。
