呼气末正压通气在婴幼儿心脏术后防治低氧血症的应用

The Use of PEEP in Prevention and Treatment of Hypoxemia in Infants after Cardiac Operation

呼气末正压通气是使呼气末气道压力高于大气压的一项通气技术。本文通过对100例婴幼儿心脏病患者应用0.2～0.8KPa的呼气末正压通气的护理观察及统计学分析,显示适度的呼气末正压通气可改善通气、换气功能、明显提高PaO_2(动脉血氧分压)、SaO_2(末稍血氧饱合度),对防治心脏术后低氧血症有显著疗效。

Positive End-Expiratory Pressure (PEEP) means the pressure in the airway is above the atmospheric pressure at the end of expiration. In this article, 100 infants with congenital heart disease who received 0.2 - 0.8 KPa of PEEP are intensively cared and statistically analysed. The results suggested that appropriate PEEP can improve ventilation and oxygen exchange, raise PaO2( arterial partial pressure of oxygen) and SaO2 (arterial O2 saturation) and can effectively prevent and treat hypoxemia after operation.
