What oxygen concentration should be used when beginning ppv for 34 week neonate?

When beginning positive pressure ventilation (PPV) for a 34-week neonate, it is recommended to start with an initial oxygen concentration of 21% (room air) and titrate based on the infant's oxygen saturation levels. Adjust the oxygen concentration gradually to maintain oxygen saturation within the target range (usually 90-95%). Close monitoring and frequent assessment are essential to prevent both hypoxia and hyperoxia.
