AED should be applied to cardiac arrest patients as soon as available
if you witness cardiac arrest, begin CPR and apply AED as soon as available. For children:

if an infant or small child is breathing, then provide prompt transport. allow the child to stay in whatever position is most comfortable.
in a child with a tracheostomy tube in the neck, remove the mask from the BVM and connect it directly to the tracheostomy tube to ventilate the child–> a face mask with one-way valve or other barrier device over the tracheostomy site can be used
