I’ve looked it up. The teams even have AEDs with the equipment that they travel with. The conjecture that AEDs weren’t used because they weren’t available is nonsense.
*** AED (automatic external defibrillators) are routinely on both NFL sidelines and even brought on the plane and bus with the traveling team. The defibrillation (shock) happened on the field to convert Hamlin’s rhythm to allow his heart to beat again.***
I’m sure there are other sources.
THANK YOU for describing what an AED is.
