Approximately 100,000 people suffer an out-of-hospital cardiac arrest every year* - around 250 individuals every day. Survival rates remain stubbornly low, with just one in 10 people recovering, but we can all make a difference by learning lifesaving CPR skills.

A staggering 80% of out-of-hospital cardiac arrests take place in the home. CPR is a skill for everyone, yet almost half of UK adults (43 per cent) have never learned these techniques. Every minute without CPR and defibrillation reduces the chance of survival from cardiac arrest by 10%. By providing training, raising awareness and offering resources that teach people how to react when someone collapses and stops breathing normally, we can save lives now and in the future.

This Learn CPR webpage covers the steps involved in providing lifesaving CPR to adults, children and babies, as well as how to use an Automated External Defibrillator (AED). However, we recommend that everyone take a face-to-face workshop to learn and practise these essential skills.
