What is the most crucial step when administering artificial respiration?

When administering artificial respiration, one of the most critical steps is to clear the victim's airways. This step is essential because if the airway is obstructed by foreign objects, fluids, or the tongue, air cannot flow properly to the lungs. Clearing the airway allows for effective ventilation, which is vital for restoring normal breathing and oxygenating the victim's blood. Only once the airway is clear can you proceed with artificial respiration techniques effectively, ensuring that the air you are trying to deliver actually reaches the lungs.

The importance of this step cannot be overstated, as an unobstructed airway is the foundation of successful artificial respiration. Without it, efforts to breathe for the victim are significantly compromised, which can lead to further complications or worsening of the victim's condition.
