A third of Brits are afraid to give CPR to a woman because they are worried about touching their breasts, new research has shown.

St John Ambulance, which has its headquarters in Devizes, has released research which also shows 33 per cent of men are concerned they will be accused of "inappropriate" touching when giving chest compressions to a woman in cardiac arrest in public, compared to 13 per cent of women.

To address this issue, St John Ambulance has launched a campaign with Chelsea Women’s captain, Millie Bright, broadcaster and DJ, Ashley James, social content creator and disability campaigner, Lucy Edwards, and activist, Sharon Gaffka.

It has the message "It’s OK to Save My Life" on the front, along with a reminder of the steps needed to respond to a cardiac arrest.

However, 38 per cent of people admitted their discomfort increased knowing the defibrillator pads need to be placed on bare skin on the chest.

Nearly half of the men surveyed said they would feel less comfortable using a defibrillator on a woman knowing her clothing, including a bra, might have to be removed, compared to 31 per cent of women.

Footballer Millie Bright said: "I’ve had the experience of being on the pitch when someone suffered a suspected cardiac arrest, and it was terrifying.

"To learn that as a woman I am more at risk because people are uncomfortable to provide help due to my gender is shocking."

Training can make a significant difference in addressing this gender disparity, with 64 per cent of respondents agreeing their comfort levels would increase with the right support and training.

"These concerns are frequently raised in our training sessions.

"Our message to people is that it is always better to do something than nothing in these circumstances."
