Arterial blood gas values, rate of pulmonary nitrogen washout, respiratory rate, arterial blood pressure, heart rate, and cardiac output were determined during ventilation of six anesthetized horses, with a demand valve. The horses were allowed to ventilate spontaneously, or intermittent positive pressure ventilation was utilized. When compared with spontaneous ventilation, intermittent positive pressure ventilation caused a significant increase in the rate of pulmonary nitrogen washout and a significant decrease of arterial carbon dioxide. It was concluded that intermittent positive pressure ventilation with a demand valve provides a simple method for resuscitation of horses.
在对六匹麻醉马使用按需阀进行通气期间，测定了动脉血气值、肺氮清除率、呼吸频率、动脉血压、心率和心输出量。这些马被允许自主通气，或者采用间歇正压通气。与自主通气相比，间歇正压通气导致肺氮清除率显著增加，动脉二氧化碳显著降低。得出的结论是，使用按需阀进行间歇正压通气为马的复苏提供了一种简单的方法。
