How many compressions should be performed before checking for an object in the mouth of an unresponsive adult?

In a situation where you need to perform CPR on an unresponsive adult and suspect that there may be an airway obstruction caused by a foreign object, the correct protocol is to conduct 30 chest compressions first. This is because initiating circulation through effective chest compressions is the immediate priority in cardiopulmonary resuscitation.

Performing these compressions helps to maintain blood flow to vital organs, especially the brain, while you address any potential obstruction. After the 30 compressions, you would then check the mouth for any visible objects that could be blocking the airway. This sequence is critical to ensure that the patient has a chance for oxygenated blood flow before further interventions like clearing the airway.

In summary, the emphasis on performing 30 compressions aligns with established BLS guidelines designed to maximize the chances of successful resuscitation in a victim experiencing cardiac arrest with a possible obstructed airway.
