Trainer Tips: How to perform CPR on an adult
CPR is essential in surviving from a cardiac arrest. The first three minutes after a cardiac arrest are the most important meaning bystander intervention is critical for survival.
- Check for a response. Gently shake the casualty’s shoulders and ask loudly: ‘Hello, can you hear me?’
- If there is no response, shout for help.
- Open the casualty’s airway by placing one hand on their forehead and the fore and middle fingers on your other hand on the casualty’s chin. Gently tilt the casualty’s head back , while making sure to keep their mouth open.
- Put your ear to the casualty’s mouth, looking down at their chest. Look, listen and feel for ten seconds to see if they are breathing.
- If the casualty isn’t breathing, call 999 or 112.
- Kneel beside the casualty, and place one hand on the centre of the chest.
- Place the heel of your other hand on top of the first, and interlock your fingers.
- Lean over the casualty. Keep your arms locked straight, and press down vertically 5 to 6 cm to begin chest compressions. When releasing the pressure between chest compressions, do not remove your hands from the casualty’s chest.
- Complete 30 compressions. Try to keep at a rate of 100-120 compressions per minute.
- After 30 compressions, tilt the casualty’s head back again. Pinch the nose and lift their chin with the tips of your fore and middle fingers. Take a deep breathe, and place your lips over the casualty’s mouth to ensure a good seal.
- Blow into the casualty’s mouth for a second, and watch for the chest rising and falling.
- Give a second rescue breath.
- Continue the cycle of 30 compressions and two rescue breaths until an ambulance arrives or you are too exhausted to continue.
