Final answer:
The ratio to use for resuscitation of an infant or child when 2 rescuers are present is 15:2.
Step-by-step explanation:
The resuscitation ratio refers to the ratio of chest compressions to rescue breaths during cardiopulmonary resuscitation (CPR). CPR is an emergency procedure performed on individuals experiencing cardiac arrest or respiratory failure to maintain blood circulation and oxygenation until more advanced medical intervention can be administered.
The ratio to use for resuscitation of an infant or child when 2 rescuers are present is 15:2. This means that for every 15 compressions, there should be 2 breaths given. This ratio helps ensure adequate circulation and oxygenation during resuscitation.
