早产儿鼻塞持续气道正压通气起始压力由5cmH2O改为7cmH2O并不能减少机械通气的需要

Initiating nasal continuous positive airway pressure in preterm neonates at 5 cm as against 7 cm did not decrease the need for mechanical ventilation

目的新生儿泡泡鼻塞持续气道正压通气（nasal continuous positive airway pressure, nCPAP）优化的起始压力尚不明确。比较呼吸窘迫早产儿的泡沫鼻塞持续气道正压通气起始压力由5cmn：O改为7cmH2O是否减少机械通气的需要。
