If you suspect that a person is experiencing an opioid overdose and they are unresponsive and not breathing, what should you do immediately after calling 9-1-1?

In the scenario of a suspected opioid overdose, the most critical immediate action following the call to emergency services is to begin CPR if the person is unresponsive and not breathing. CPR, which involves chest compressions and rescue breaths, is necessary to maintain blood flow and oxygenation to the vital organs until professional help arrives.

Starting CPR quickly is key, as it can significantly increase the individual's chances of survival by preventing further brain damage and other complications due to lack of oxygen. While administering naloxone is an important step in treating an opioid overdose, it is most effective when combined with CPR or when initiated immediately after CPR has begun. This ensures that oxygen supply is being maintained while the effects of the opioid are being counteracted with naloxone.

Waiting for help or relying solely on artificial respiration without CPR may not provide sufficient support during this critical moment, as effective circulation is crucial in the event of an unresponsive individual who is not breathing.
