I am in the process putting together a first aid kit for situations where a wait of more than two hours is possible before to getting the patient to a hospital or into ASR/air ambulance? This could be following a ditching or forced landing into remote areas.
In the case that someone has chest pains or symptoms of a heart attack, is it worth carrying GTN spray. The guidance given below from Guys Hospital (UK).

Also following cold water immersion in the over fifties, is GTN spray worth carrying, again on the onset of chest pains?
I would be interesting to have the input of para medics, doctors or cardiologists on this one.
