What is the normal tidal volume for a child?

The normal tidal volume for a child is typically considered to be in the range of 5-7 mL/kg of body weight. This value is important because tidal volume refers to the amount of air that is inhaled or exhaled during a normal breath. In pediatric patients, the tidal volume differs from that of adults and is calculated on a per-kilogram basis. Accurate tidal volume delivery is crucial during resuscitation efforts, especially in critical situations where overventilation or underventilation can lead to complications.

This volume is appropriate for achieving adequate ventilation while minimizing the risk of ventilator-induced lung injury, which can occur if the tidal volume is too high. The lower range (5-7 mL/kg) allows for safer mechanical ventilation strategies in pediatrics. The other values presented in the choices tend to be outside the appropriate range for children, which could lead to inadequate or excessive ventilation if utilized.
