Should one start chest compressions CPR on a person who passes out after unsuccessful attempts at Heimlich?

No, chest compressions should not be started on a person who has passed out after unsuccessful attempts at the Heimlich maneuver. Passing out, also known as syncope, is usually caused by a temporary drop in blood flow to the brain and does not require chest compressions.

Here's what to do if someone passes out after unsuccessful attempts at the Heimlich maneuver:

1. Check for Responsiveness: Gently shake the person and shout, "Are you okay?" If they are unresponsive, call for help or 911 immediately.

2. Airway and Breathing: Ensure their airway is clear and that they are breathing normally. If they are not breathing, start rescue breaths.

3. Recovery Position: If they are breathing normally, place them in the recovery position, which involves lying them on their side and tilting their head back slightly to maintain an open airway. This helps prevent choking and aspiration.

4. Stay with Them: Stay with the person and continue monitoring their breathing until medical help arrives.

Remember that chest compressions are specifically used for cardiac arrest, when a person's heart has stopped beating or is not pumping effectively. Passing out, on the other hand, is typically not a life-threatening condition and does not require chest compressions. It's important to provide appropriate care based on the specific situation.
