Abstract

Anaesthetized cats breathing 100% O2, air or 14% O2 received intravenous infusions of KCl (0.075 mmol/kg body weight per 30 sec). Ventilation increased significantly during the infusion and returned to control values within 10 sec of its completion. The ventilatory response to acute changes in arterial plasma potassium concentration is not abolished by hyperoxia. Some of these findings have already been briefly communicated (Band et al., in press).

摘要

对吸入100%氧气、空气或14%氧气的麻醉猫静脉输注氯化钾(每30秒0.075毫摩尔/千克体重)。输注期间通气显著增加,并在输注结束后10秒内恢复到对照值。高氧并不会消除对动脉血浆钾浓度急性变化的通气反应。其中一些研究结果已简要发表(班德等人,即将发表)。
