本文作者研究了婴儿特发性呼吸窘迫综合征(以下简称IRDS)应用持续气道正压法(Continuous positive airway pressure,以下简称CPAP)与常规供氧法的死亡率比较。材料和方法 cPAP系使用一紧密贴合的面罩连接在麻醉袋上。吸入的气体在氧稀释器内混合后,通过面罩肘管输送,气道正压由改变吸入气体流量而调正,并以气体压力计测定之。当流量大于每分2升时,面罩下的二氧化碳滞留不能测出。吸入氧浓度使用刻度氧分析器测定。
The authors studied the mortality of infants with Idiopathic Respiratory Distress Syndrome (hereinafter referred to as IRDS) using continuous positive airway pressure (CPAP) compared with conventional oxygenation. Materials and Methods The cPAP system was attached to the anesthetic bag using a snug fit mask. Inhaled gas is mixed in the oxygen diluter and delivered through the mask elbow. The positive airway pressure is adjusted by changing the flow of inhaled gas and measured with a gas pressure gauge. When the flow rate is greater than 2 liters per minute, the mask of carbon dioxide can not be measured stranded. Inhaled oxygen concentration was measured using a dialysis oxygen analyzer.
