Contents of a BLS Checklist
A typical Basic life support checklist includes these key steps:
1. Scene Safety Assessment
- Look for dangers (e.g., electrical risks, chemical spills, unstable objects).
- Use personal protective equipment (PPE) if available and needed.
- Count how many people need help.
2. Check for Responsiveness
- Gently tap the person’s shoulders.
- Ask loudly, “Are you okay?”
- See if the person responds or not.
3. Activate Emergency Response System
- Call for help or activate the emergency system.
- Ask for an Automated External Defibrillator (AED) if it’s available.
4. Check for Breathing and Pulse
- Open the airway by tilting the head and lifting the chin.
- Look for the chest moving up and down.
- Listen for breathing sounds.
- Feel for air from the person’s nose or mouth.
- Check for a pulse (neck pulse for adults and children, arm pulse for babies).
- See if the person is breathing normally or not.
5. Start High-Quality CPR
- Place your hands on the lower part of the chest.
- Push down at a rate of 100-120 compressions per minute.
- Press the chest down 5-6 cm (2-2.4 inches) for adults.
- Let the chest rise completely between compressions.
- Keep interruptions to a minimum.
6. Give Rescue Breaths
- After 30 chest compressions, give 2 rescue breaths.
- Each breath should last 1 second and should make the chest rise.
- Go back to chest compressions immediately after the second breath.
7. Use of AED (if available)
- Turn on the AED and follow its instructions.
- Place the AED pads on the person’s bare chest.
- Make sure no one is touching the person while the AED checks.
- Give a shock if the AED tells you to.
- Continue CPR after the shock or if no shock is advised.
8. Continue CPR and AED Use
- Do CPR in cycles: 30 compressions, 2 breaths.
- Change people performing chest compressions every 2 minutes.
- Keep going until professional help arrives or the person starts breathing.
9. Recovery Position
- If the person starts breathing normally, put them in the recovery position.
- Keep watching their breathing and be ready to start CPR again if needed.
10. Post-Resuscitation Care
- Look after the person and keep an eye on their condition until emergency services arrive.
- Be ready to give helpful details to medical staff.

Adult CPR and AED Checklist [Download and Print]
Adult CPR and AED CHECKLIST
This checklist summarizes the essential steps of Adult CPR and AED use. Remember, this is a quick reference. Refer to your full training materials and instructor for detailed explanations and proper technique.
Before You Begin:
- Find a quiet, distraction-free environment.
- Set a metronome to 110 beats per minute (BPM) (you or the instructor can use it).
- Ensure the instructor can hear the metronome, manikin click (for compression depth), and your voice clearly. Adjust audio settings if needed.
1. Scene Safety – ALWAYS CHECK
Before approaching a person in distress, ensure the scene is safe for yourself and others.
2. Unresponsive Adult (Call for Help & Check Responsiveness)
- Call Emergency Services: Immediately dial 999 (UK) or your local emergency number and ask for an ambulance.
- Check Responsiveness: Tap or shake the person and shout loudly. Ask, “Are you alright?”
3. If Unresponsive (Open Airway & Check Breathing)
- Open the Airway: Tilt the head back with chin lift or use jaw thrust (if needed) to open the airway.
- Check for Breathing: Look, listen, and feel for chest rise for no more than 10 seconds.
4. Not Breathing Normally (Begin CPR)
- Chest Compressions:
- Place the heel of your hand on the lower half of the sternum (breastbone).
- Interlock your fingers and keep your arms straight.
- Perform 30 high-quality chest compressions at a rate of 100-120 compressions per minute (BPM) for 15-18 seconds.
- Aim for at least 2 inches of compression depth with complete chest recoil after each compression.
5. Deliver Breaths (if using a barrier device)
- Give 2 Breaths: Pinch the nose shut, create a seal with your mouth over the person’s mouth, and deliver 2 breaths, each lasting 1 second, observing visible chest rise.
6. Repeat CPR Cycles (Compressions & Breaths)
- Continue cycles of 30 chest compressions followed by 2 breaths until the AED arrives or the person starts breathing normally. Aim for less than 10 seconds between cycles.
7. AED Available (Follow AED Prompts)
- Power on the AED: Turn on the AED as soon as it arrives.
- Follow AED prompts: Attach the AED pads according to the manufacturer’s instructions.
- Clear the Patient: Say “Clear” and ensure everyone is clear of the patient when prompted by the AED for analysis and potential shock delivery.
- Follow instructions: If a shock is indicated, the AED will guide you through delivering the shock safely.
8. Resume CPR After AED
- Resume Compressions: After shock delivery (if applicable), say “Resume compressions” and instruct the instructor to resume compressions immediately.
- Continue CPR: Continue cycles of chest compressions and breaths (if using a barrier device) following AED prompts until help arrives or the person starts breathing normally.
Purpose of a BLS Checklist
The BLS checklist is important for many reasons in emergency situations:
- Standardisation of Care: It helps make sure that all rescuers follow the same steps, no matter how trained they are. This consistency improves the chances of saving lives during a cardiac arrest.
- Memory Aid: In stressful situations, it’s easy to forget key steps. The checklist serves as a reminder, making it easier for rescuers to follow the right order of actions.
- Quality Assurance: By following the checklist, rescuers can be sure they are giving high-quality CPR and following the latest guidelines. This is important as guidelines change over time with new research.
- Training Tool: The checklist is useful for both new learners and experienced people. It helps practise and remember the right actions during BLS training.
- Performance Evaluation: Teachers and examiners can use the checklist to see if rescuers are doing all the important steps correctly during training or when renewing their certification.
- Legal Protection: In some places, using a recognised BLS checklist can protect rescuers legally. It shows that they followed the proper steps in their care.
- Better Patient Outcomes: By ensuring each step is done correctly, the checklist can help improve survival rates and recovery for people who have a cardiac arrest.
- Confidence Booster: For people who don’t do CPR often, the checklist can make them feel more confident when helping in an emergency.
- Adaptability: While BLS principles stay the same, checklists can be adjusted to fit different places (like hospitals or outside) or patient needs (like adults or children).
- Works with Advanced Life Support: The checklist works alongside more advanced life-saving measures. It helps when extra support is needed as it smoothly transitions into more advanced treatments.

Implementing BLS Checklists Effectively
To get the most out of BLS checklists, organisations and training programs should keep the following in mind:
- Regular Updates: Make sure the checklists are updated often to follow the newest guidelines from trusted sources like the International Liaison Committee on Resuscitation (ILCOR) or local resuscitation councils.
- Accessibility: Ensure that checklists are easy to get, in different forms like pocket cards, posters, or apps. This helps meet different needs and situations.
- Training Integration: Include the use of checklists in BLS training programs and highlight their importance and how to use them properly.
- Simulation Practice: Practice with checklists during training exercises to help people get comfortable using them in real-life situations.
- Feedback Mechanisms: Set up ways for people to share their thoughts on how useful and easy the checklists are. This helps improve them over time.
- Cultural Adaptation: Adapt the checklists to fit different cultures and languages to make sure they are effective for everyone.
- Team Training: Practice using checklists in team settings to improve teamwork and communication when performing CPR or resuscitation.
