What should you do if the first attempt at rescue breathing fails?

If the first attempt at rescue breathing fails, checking for human error is essential. This step involves assessing the technique used for delivering breaths. Proper technique is crucial for the effectiveness of rescue breathing. One might need to ensure that the airway is clear and positioned correctly, that the seal is adequate when using a barrier device, and that air is being effectively delivered into the victim's lungs.

By focusing on potential human error, you can identify and correct any mistakes that could hinder effective ventilation, such as tilting the head incorrectly or not sealing the mask properly. This ensures that when you attempt rescue breathing again, you're maximizing the chances of success, which is critical in emergency situations where timely and effective action can save a life.

Taking this approach emphasizes the importance of technique and accuracy over simply repeating the failed action without reassessment, enabling a more informed response to the situation.
