What range of respiratory rate (RR) is commonly used for initial infant ventilation?

Starting infant ventilation with a slower rate helps you establish ventilation gently and safely before increasing support. Infants have very compliant lungs and small airways, so delivering breaths too quickly can cause overventilation, high peak pressures, and air trapping, while also making it harder to judge how the infant is responding. A slower initial rate gives you time to observe chest rise, skin color, heart rate, and to assess how the infant is actually ventilating. You can then adjust the rate (or tidal volume) based on clinical response and, if needed, blood gases to reach appropriate CO2 and oxygenation levels. This cautious, titratable approach reduces the risk of ventilator-induced lung injury and helps you tailor support to the infant’s needs from the outset.
