Our next door neighbour fell off a ladder while cutting branches a few weeks back. Found him lying in the garden. Broken legs, broken ribs, broken skull.

So we phoned emergency, and a paramedic was there within minutes, and an ambulance a little later to carry him off to hospital.

We found his keys and locked up his house, and made sure his garden was looked after while he was getting better, visited him in hospital, and contacted his daughters.   That's what neigbours can do - as well for him he wasn't dependent on us for getting medical care, because we weren't up to that. That's what the NHS is for.
