When giving breaths using a face shield, what is the first step?

Opening the airway using the head-tilt/chin-lift technique is the first step when giving breaths using a face shield because it ensures the airway is clear and allows for adequate ventilation. This technique helps to lift the tongue off the back of the throat, which can obstruct airflow, thus making it easier to deliver breaths effectively.

It is essential to establish a clear airway before providing breaths; otherwise, air may not enter the lungs properly, reducing the effectiveness of the rescue breaths. Once the airway is opened, you can proceed to use the face shield to provide breaths securely, ensuring an effective seal and proper delivery of air.
