“He had no pulse. Three other people were already helping. We all went straight into resus [resuscitation] mode.
“CPR is a big part of the work I do. You go into autopilot. Your training kicks in.”
After four rounds of CPR and two shocks, Stevenson came round and began to talking.
“We got a return of spontaneous circulation,” Page said. “It was an incredible moment.”
Afterwards, Page went to work and Stevenson was taken to the Royal London Hospital “awake and well enough to call my wife Karen from the ambulance”.
He said words were “too small to express how massively grateful” he was to Page and the others who saved his life.
Joining Stevenson in speaking to the BBC, Page said: “It’s always a strange feeling…but it does really make you feel like what you’ve done has been worthwhile and you really have made a difference.”
