What is the correct technique to perform rescue breathing?

The correct technique for performing rescue breathing involves opening the airway and giving two breaths followed by cycles of chest compressions. This method is essential in cases where the person has stopped breathing but still has a pulse—a condition known as respiratory arrest. By initially providing two rescue breaths, rescuers can quickly deliver oxygen to the lungs, which is vital for maintaining oxygen supply to the brain and other organs.

After the initial breaths, chest compressions are included in the sequence to promote blood circulation. This combination effectively addresses both the lack of breathing and the need for blood flow in the body. The rhythm of alternating breaths and compressions maximizes the chance of restoring effective breathing and circulation until professional help arrives.

In contrast, other options such as providing chest compressions without breaths, performing abdominal thrusts, or giving only breaths without compressions would not adequately address the critical requirement of supporting both breathing and circulation during a potential life-threatening situation.
