Abstract
Twenty two babies receiving artificial ventilator support were studied on 29 occasions to determine the effects of low levels of positive end expiratory pressure. Mean positive end expiratory pressure during these studies was 2.6 cm H2O. Changes in tidal volume, minute volume, compliance, and transcutaneous gas trends produced by the use of positive end expiratory pressure were investigated. Positive end expiratory pressure consistently caused a rise in transcutaneous oxygen tension. Changes in transcutaneous carbon dioxide tension after the introduction of positive end expiratory pressure were less consistent and not of the same magnitude as the observed reduction in minute ventilation. Compliance values fell with the use of positive end expiratory pressure.
摘要
对22名接受人工通气支持的婴儿进行了29次研究，以确定低水平呼气末正压的影响。这些研究期间的平均呼气末正压为2.6厘米水柱。研究了使用呼气末正压后潮气量、分钟通气量、顺应性和经皮气体趋势的变化。呼气末正压持续导致经皮氧分压升高。引入呼气末正压后经皮二氧化碳分压的变化不太一致，且与观察到的分钟通气量减少幅度不同。使用呼气末正压时顺应性值下降。
