Which of the following steps are correct when providing rescue breathing?

Opening the airway is a crucial step in providing rescue breathing. This is essential because it allows for unobstructed airflow into the lungs, facilitating proper ventilation. The most effective way to open the airway is typically through the head-tilt-chin-lift maneuver, or by using the jaw-thrust method in cases where there might be neck injuries.

Each step in the rescue breathing process is designed to ensure that the victim receives sufficient oxygen, and opening the airway is foundational to achieving that goal. When the airway is not properly opened, any effort to provide rescue breaths may be ineffective, leaving the victim without the necessary oxygen they need to survive until more advanced medical help arrives.

While checking for unresponsiveness is important, it is often done prior to opening the airway. Ventilating with insufficient air or incorrectly pinching the nose can also hinder effective rescue breathing, hence why these options do not contribute to the correct procedure.
