CPR is used on a non-breathing casualty to circulate oxygen around the body until normal breathing resumes. It can be learnt by watching this 80 second video, but we strongly recommend signing up to a hands on first aid course.
Dial 999 / 112
Always contact the emergency services stating your location and that a person has stopped breathing. The emergency services will arrive quicker if they are called with this information immediately.
Deliver 30 chest compressions in the centre of the chest, at a rate of 100-120 per minute and at a depth of 5-6 cm. Put your hand under the casualty's armpit and slide across to the centre of the chest to help position yourself.
Deliver two rescue breaths with a gap in between. Each breath should be moderate, lasting for about one second and should make the chest gently rise. It’s possible to use a CPR face shield or skip the breaths entirely if you do not wish to deliver them.
