What is the typical peak inspiratory pressure (PIP) range in initial infant ventilation?

Starting ventilation in newborns aims to inflate the lungs safely enough to deliver a adequate tidal volume without causing injury. Neonatal lungs are often stiff and prone to collapse, so a peak inspiratory pressure in the 20s, roughly 20–30 cm H2O, is used to achieve a reasonable tidal volume (about 4–6 mL/kg) while keeping pressures from being too high. Pressures in the lower ranges (10–15 or 5–10) risk under-ventilation and atelectasis, whereas pressures in the higher ranges (30–40) raise the chance of volutrauma or barotrauma in delicate neonatal lungs. In practice, you monitor chest rise, oxygenation, and ventilation effectiveness, keep a modest PEEP (around 4–6 cm H2O) to prevent collapse, and adjust the PIP in small steps toward the target tidal volume as the infant’s lung mechanics respond.
