After performing the head tilt-chin lift and still finding no normal breathing, what should you do next?

The appropriate action after performing the head tilt-chin lift and not finding normal breathing is to provide rescue breaths. This is due to the fact that the absence of normal breathing indicates a critical situation where the individual may need immediate assistance in breathing.

Delivering two rescue breaths, taking approximately one second each, helps to ensure that air is effectively introduced into the lungs, which is crucial for oxygenating the person's blood. This method mimics natural breathing and is designed to provide enough air to establish ventilation without causing excessive pressure that could lead to complications such as gastric inflation.

The sequence of administering rescue breaths emphasizes their urgency in an emergency situation. After the two rescue breaths, further assessments can determine if additional actions like chest compressions are necessary, depending on the individual's response.
