If bystanders do CPR after a cardiac arrest, they can save lives.
If you’re a bystander, and you do CPR, you can double or even treble survival rates.
In the UK, there are more than 30,000 out of hospital cardiac arrests (OOHCAs) every year. But only 7-9% of people survive. In other countries, survival after an OOHCA is much higher : it’s 21% in North Holland, 20% in Seattle and 25% in Norway.
The low survival rates in England are partly because less than half of bystanders here perform life saving CPR. This compares with almost three quarters of Norwegians intervening. Survival rates there are up to three times higher.
Every minute without CPR or defibrillation can reduce the chances of survival by around ten per cent. After ten minutes with no CPR or defibrillation, only two out of 100 victims (or less) have a chance of surviving.
