For children and infants in respiratory arrest, each ventilation delivered should last how many second(s)?

For children and infants in respiratory arrest, each ventilation delivered should last about 1 second. This duration ensures that the breath is delivered smoothly and allows the chest to rise adequately during ventilation. It is important to deliver ventilations at a rate that provides sufficient time for the lungs to inflate properly while also minimizing the risk of overinflation or barotrauma, which can occur if the breath is delivered too forcefully or too quickly.

If a ventilation is given for too long, it may not only be ineffective but could also lead to other complications, such as increased intrathoracic pressure, which can impede venous return to the heart. Therefore, the recommended practice is to aim for a ventilation duration of approximately 1 second, which helps to maintain adequate airway management and supports the child or infant's needs during an emergency situation.
