Douglas Chamberlain obituary

Cardiologist who empowered paramedics and the general public to restart hearts and save lives

If you had a cardiac arrest before the 1970s, an ambulance might arrive quickly, but almost all its crew could do was transport you to hospital, where your treatment would begin - if indeed you survived the journey. The cardiologist Douglas Chamberlain, who has died aged 94, realised that in order to start resuscitation in the vital five-minute window after the heart stopped beating, the ambulance crew needed the tools and skills to do it themselves.

Chamberlain's initiative laid the foundations for the paramedic profession nationally and internationally. Working from a district general hospital in Brighton, he set up an intensive training programme for ambulance crews, equipped ambulances with defibrillators and electrocardiogram (ECG) machines, and demonstrated through a series of rigorously documented studies that the service saved lives. The only other city in the world where non-medical professionals were using defibrillators at the time was Seattle in the US.
