When is it appropriate to attach supplemental oxygen to a BVM resuscitator during CPR for a child?

Attaching supplemental oxygen to a bag-valve-mask (BVM) resuscitator as soon as resources are available is crucial during CPR for a child. This is because supplemental oxygen increases the amount of oxygen delivered to the lungs, enhancing the effectiveness of ventilation during the resuscitation efforts. Timely access to oxygen can help in preventing hypoxia, which is a critical concern during cardiac arrest.

In CPR protocols, the early use of supplemental oxygen along with the BVM allows for better oxygenation of the blood, even while chest compressions are being administered. The primary goal of CPR is to restore blood flow and oxygenation, and using supplemental oxygen from the onset of resuscitation supports this goal by providing the best chance for survival in a child experiencing cardiac arrest.
