Final answer:
The child BLS compression to breath ratio for two rescuers is 15:2, which involves performing 15 chest compressions followed by 2 rescue breaths as part of CPR.
Step-by-step explanation:
The child BLS compression to breath ratio for two rescuers is 15:2. This means that two rescuers should alternate giving 15 chest compressions followed by 2 rescue breaths. This is a critical technique used in cardiopulmonary resuscitation (CPR), which is a lifesaving procedure that combines chest compressions with artificial ventilation to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
During changes in rescuers to prevent fatigue, minimal interruptions in chest compressions should occur, and switching should be accomplished quickly.
