Emergency Medical Responder Practice Exam

Question: 1 / 400

How many rescue breaths should be given after 30 compressions in adult CPR?

1 rescue breath

2 rescue breaths

In adult CPR, after delivering 30 chest compressions, the correct procedure is to give 2 rescue breaths. This is part of the mouth-to-mouth ventilation technique where the rescuer provides breaths to the victim following the compressions. The rationale behind giving 2 breaths is to effectively provide oxygen to the lungs and prepare the body for continued resuscitation efforts.

This approach balances the need for chest compressions, which circulate blood, with the necessity of ventilating the lungs to ensure oxygen is delivered to the heart and brain. By giving 2 breaths after 30 compressions, rescuers can maintain a cycle that optimally supports the patient's chances of survival until advanced medical help arrives or until spontaneous circulation and breathing resume.
