In the case of an unresponsive adult, when should you call emergency services?

When dealing with an unresponsive adult, the appropriate timing for calling emergency services is essential for ensuring the best chance of survival. After determining that the adult is unresponsive, you should call emergency services promptly, ideally after initiating CPR.

The correct approach is to start CPR immediately, to provide critical chest compressions and rescue breaths, which can help maintain blood flow to vital organs until professional help arrives. Calling emergency services after two minutes of CPR allows enough time not only to begin life-saving measures but also to ensure that help is on its way without unnecessary delay.

Delaying the call until after starting CPR for five minutes may not be optimal because every moment counts in a cardiac emergency. Immediate notification to emergency services can lead to a quicker response and treatment, which is crucial for the patient's survival.

Thus, calling emergency services after two minutes of initiating CPR ensures that help is on the way while continuing essential care for the unresponsive victim.
