Question: 1 / 400

What is the correct procedure for delivering mouth-to-mouth breaths?

Open airway, pinch nose, seal mouth, give breaths

The correct procedure for delivering mouth-to-mouth breaths involves opening the airway first, which is critical to ensure that the air can effectively reach the lungs. Next, pinching the nose helps prevent air from escaping through the nasal passage, maximizing the volume of air delivered to the victim's lungs. After sealing the mouth, the provider gives breaths, ensuring that they are delivered in a controlled manner to avoid causing aspiration or over-inflation of the lungs. This sequence is essential for effective ventilation during cardiopulmonary resuscitation (CPR), allowing for sufficient oxygen delivery to the patient.

The emphasis on opening the airway first is crucial because, without a clear passage, the breaths may not provide the needed ventilation if the airway is obstructed.
