To provide effective rescue breaths, it is crucial for a rescuer to first check for normal breathing and ensure that the airway is open. This step is essential because it confirms that the person is not breathing adequately on their own and also that there are no obstructions preventing air from entering the lungs.
Ensuring that the airway is open allows the rescuer to deliver breaths effectively, maximizing the chance of oxygen reaching the lungs. If the airway is obstructed, delivering breaths may not help and could potentially cause air to enter the stomach instead of the lungs, which can lead to complications such as choking or vomiting.
Additionally, assessing for normal breathing before administering rescue breaths helps the rescuer avoid unnecessary actions if the person is already breathing effectively on their own. This systematic approach is vital in providing timely and appropriate care in an emergency situation.
