Members of the public are being urged not to give the kiss of life during CPR but to concentrate instead on chest compressions.
People should skip giving breath and pump the chest instead to the tune of the Bee Gees hit Stayin’ Alive, according to the British Heart Foundation (BHF).
It says bystanders often do not perform CPR because they are worried about doing it properly, including the ratio of breaths to chest compressions.
But research has shown that giving continuous chest compressions at 110 to 120 beats per minute - the same rate as Stayin’ Alive - is more effective than trying to do CPR with a poor rescue breath technique.
The charity hopes its new TV campaign, featuring actor Vinnie Jones, will give people the confidence to do CPR and help save a life.
It says anyone who does not have formal CPR training should skip kiss of life in favour of “hard and fast” compressions in the centre of the chest.
Chest compressions with rescue breaths will continue to be part of gold standard CPR and taught during formal training.
Ellen Mason, senior cardiac nurse at the BHF, said: “Hands-only CPR should give lots of people the confidence and know-how to help save someone in cardiac arrest, the ultimate medical emergency.”
