That’s what I was thinking I know the FoL has one, definitely worth bringing it up thoughNo way they could be sure of anything on the pitch other than no detectable pulse. You'd need a ECG to be certain, and you can't attach the electrodes while you're giving CPR.
Ideally, there should be some on the concourses, if the St Johns don't have them to hand.
