How to Administer CPR: A Step-by-Step Guide

Knowing how to respond to a cardiac arrest can save valuable time while emergency services are on their way. This guide explains the basic response for a workplace emergency; practical training is the best way to build confidence.

Recognise a cardiac arrest

If someone is unresponsive and not breathing normally, treat it as a cardiac arrest. Shout for help, ask someone to call 999 and send someone for the nearest automated external defibrillator (AED).

The basic CPR response

  1. Make sure the area is safe to approach.
  2. Check responsiveness and normal breathing.
  3. Call 999, put the phone on speaker and follow the dispatcher’s instructions.
  4. Start chest compressions in the centre of the chest and keep going with minimal interruptions.
  5. Use an AED as soon as it arrives, following its spoken prompts.

Why an AED matters

An AED analyses the heart rhythm and will only advise a shock when appropriate. It is designed to be used by members of the public, but workplace first aid training gives people the opportunity to practise the sequence and use the equipment calmly.

Build workplace confidence

Employers should assess their first aid needs and make sure suitable equipment and trained people are available. See our workplace first aid training options, or request a group booking quote for your team.
