Jon Thordarson was travelling back home from a holiday in Gran Canaria when fellow passenger Terry Potter collapsed from a cardiac arrest.
A paramedic, Jon started CPR and gave six shocks with the plane’s defibrillator before 50-year-old Terry started showing signs of life.
“I’ve spent the last seven years volunteering as part of Restart a Heart Day, teaching people how to do CPR and what to do if someone has a cardiac arrest," Jon explained to Hull Live.
