The recommended range of initial pressures for Peak Inspiratory Pressure (PIP) in infants during mechanical ventilation is typically between 20 and 30 cmH2O. This range is chosen to effectively provide adequate ventilation while minimizing the risk of barotrauma and volutrauma, which can be particularly harmful in the delicate respiratory systems of infants.

Setting the PIP within this range allows for sufficient tidal volume delivery without excessively increasing intrathoracic pressure, which can impair venous return and cardiovascular function. Additionally, the 20 to 30 cmH2O range is aligned with clinical guidelines that aim to balance effective ventilation with safety concerns, ensuring that infants receive the necessary respiratory support without causing additional lung injury.

Pressure settings outside this range may not provide optimal ventilation or cause injury; hence, beginning at 20 to 30 cmH2O is a standard practice in neonatal and pediatric intensive care settings.
