How to do CPR on an Adult – First Aid Training – St John Ambulance


If, after performing the primary survey,
you find someone who is unresponsive and not breathing normally, call for help. Ask someone to call 999 or 112 and ask
them to bring an AED if one is available, while you begin CPR immediately. If
you’re on your own make the call yourself, ideally by using a mobile on
speakerphone so that you can begin CPR as soon as possible. You will need to start with chest
compressions. Kneel down beside the casualty’s chest. Place one hand at the centre of the
chest and place the heel of the other hand on top and interlock your fingers
to lift them off the ribs. Lean over the casualty with your arms straight and press down on the chest to five to six centimetres. Release the pressure, allow the chest to come back up without removing your hands from the chest. Repeat this to give 30 chest
compressions at a rate of 100 to 120 beats per minute. This is quite fast. To help you keep pace
you can sing ‘staying alive’. After 30 chest compressions you need to give rescue breaths. If you
have not been trained or are unwilling or unable to give rescue breaths, continue
with chest compressions only until help arrives or if the casulty becomes responsive. To give rescue breaths make sure the airway is open by tilting the head back
with one hand on the forehead and two fingers under the chin. Pinch the soft part of the nose and allow their mouth to fall open. Take a deep breath and seal your mouth
around theirs. Blow steadily into their mouth giving a rescue breath in about
one second, their chest should rise. Remove your mouth from theirs and watch their chest fall. Give them two rescue breaths like this. Continue to alternate 30 chest
compressions and two rescue breaths. If someone can help you perform CPR you can swap over every one to two minutes with minimal interruption to chest
compressions. If there’s someone there who can help if they have brought you an
AED ask them to turn it on and follow the instructions while you continue CPR. Continue CPR until emergency help
arrives and takes over, the casualty starts to show signs of becoming
responsive, they start breathing normally or opening their eyes, or you become too
exhausted to continue. If they do start breathing normally again place them in the
recovery position, monitor them and prepare to start CPR again if necessary. So remember: if you come across an adult
who is unresponsive and not breathing normally, call for help. Ask someone to call 999 or 112 for
emergency help and ask them to bring an AED. If you are on your own make the call yourself ideally by using a mobile on
speakerphone so you can begin CPR. Give 30 chest compressions followed by two rescue breaths and continue giving 30 chest compressions and 2 rescue breaths until
help arrives or they become responsive. If an AED is available continue CPR while instructions from the device are followed by your helper And that’s how we perform CPR. If this video has been helpful to you,

  1. od we still need to give rescue breaths> because I had read articles some says it is not important anymore because brain has enough oxygen for 5minutes? i dont know

  2. hi,I want to know how to registering for a course,I want to register a first aid course, how much? plz help I want to make it.tnkx

  3. Also stop CPR when the AED instructs you to do so.
    Also your chin lift was poor with no raised elbow and pressure against the chin which would close the primary airway.

  4. "To help you keep pace you can sing staying alive" .Starts singing ," ha ha staying live staying alive ha ha " !!!!! Good info!

  5. I'm struggling with some of his words. I think the accent should be a bit clearer for such an important video.

  6. I am a certified lay rescuer, and I think he didn't mention the important parts, Checking for CAB of life such as Circulation, Airway, and Breathing, He didn't instructed the importance of counting aloud while giving 30 compression and checking for Circulation after 5 cycles. It must be, 30 compression, 2 rescue breaths, 5 cycles and check the pulse then repeat if the patient has still no pulse rate.

  7. I'm a sea cadet, and on our intermediate first aid. NB- Our instructor is one of the many ambulance crew. He told us that 'Stayin Alive' by the Bee Jees, changed speed, we did a challenge on a CPR , how many compressions we could do in 1 minute, I, got 174 compressions, and plus, what if you hadn't heard of that song?? What other song are you going to use.
    P.S – you are allowed to argue, but I am hopefully going to complete my intermediate tonight at cadets so I will have probably know the awnser to my argument/point.
    Kx

  8. Thanks for this. I work in a public place, often alone, and I live in fear of being in a situation where I would need to do this! These instructions really help. (Yes, I have asked my boss if I can go on a First Aid course. I'm still waiting…..)

  9. Dont forget the steps before cpr, which are also very important. So we did a video on that topic too, maybe there are additional important informations
