When performing CPR on an unresponsive person believed to be choking, what modification should be implemented?

In the scenario of performing CPR on an unresponsive person who is suspected of choking, it is crucial to ensure that any obstructing object is cleared as quickly as possible. When the person is unresponsive, checking the mouth after compressions is vital to identify if any obstruction is present. Each time compressions are performed, it is appropriate to pause briefly to check the mouth for any visible objects that could be causing the airway obstruction. This combination of chest compressions and checking for obstructions maximizes the chance of restoring an open airway quickly, which is critical for effective CPR.

This modification is essential in a choking situation, as failure to address the obstruction could result in inadequate oxygenation and lead to further complications. Choosing this option ensures that you actively manage the choking hazard while also providing necessary compressions.
