CPR and using a defibrillator (AED)

When the heart stops (cardiac arrest), every minute without CPR lowers the chance of survival. Dubai sees about 1,600 cardiac arrests a year, with survival around 5 percent, which is why the city is training residents and installing defibrillators. Hands-only CPR is something you can learn today.

Recognise cardiac arrest

  • The person is unresponsive: no reaction when you gently shake their shoulders and ask loudly, 'Are you OK?'
  • Open the airway with head tilt and chin lift, then check breathing for up to 10 seconds.
  • If they are not breathing, or only making occasional irregular gasps, treat it as cardiac arrest.
  • Shout for help. Have a helper call 998 while you start CPR; if you are alone, call on speakerphone so you can start straight away.
  • St John Ambulance: do not leave the casualty to look for a defibrillator yourself. Send a helper for one.

Hands-only CPR, step by step

  • If it is safe, move them onto their back on a firm surface.
  • Kneel beside them. Put the heel of one hand on the middle of the chest and your other hand on top.
  • Keep your arms straight with your shoulders directly over your hands.
  • Press straight down about 5 to 6 cm, then let the chest come back up fully before the next push. Resuscitation Council UK: at least 5 cm but not more than 6 cm.
  • Push at 100 to 120 compressions per minute, with as few pauses as possible.
  • If you are not trained in rescue breaths, or are unwilling to give them, give continuous chest compressions without stopping.

Rescue breaths (30:2), if trained and willing

  • After 30 compressions, open the airway with head tilt and chin lift and pinch the soft part of the nose closed.
  • Seal your mouth over theirs and blow steadily for about one second until the chest rises.
  • Let the chest fall, then give a second breath.
  • Make no more than two attempts, then return straight to 30 compressions even if the breaths did not go in.
  • Keep repeating 30 compressions and 2 breaths.

Using an AED (defibrillator)

  • Switch it on as soon as it arrives and follow its spoken instructions; AEDs are designed for untrained people.
  • Have a helper expose the chest (remove or cut clothing) and dry it if it is wet.
  • Adult pads: one on the upper right chest below the collarbone, the other on the lower left side below the armpit. Keep compressions going while the pads go on.
  • When the AED analyses the heart rhythm, make sure no one is touching the person.
  • If a shock is advised, make everyone stand clear and press the shock button when told (fully automatic models shock by themselves).
  • After the shock, or if no shock is advised, continue CPR for two minutes until the AED reanalyses.
  • If they start breathing normally, coughing or speaking, put them in the recovery position and leave the pads attached.

Where to find AEDs in the UAE

  • St John Ambulance notes AEDs are often found in workplaces, schools, gyms and other public areas.
  • Dubai's 'Heart Safe City' initiative (launched in 2022 by the Dubai Health Authority, Dubai Police and DCAS) reported 3,200 AEDs already provided, in places such as malls, airports and community centres.
  • That plan aimed to provide 10,000 AEDs and train over 100,000 people in CPR over five years.
  • If you do not know where the nearest AED is, the 998 call handler can help direct you.
  • Notice where the AED boxes are at your school, gym and local mall so you know before you need one.

When to stop

  • Keep going until emergency help arrives and takes over.
  • Stop if the person starts breathing normally.
  • Pause when the defibrillator is ready to analyse or shock.
  • CPR is exhausting: if there is a helper, swap every one to two minutes to keep compressions effective.

Practise in real life

Tick each one off when you have done it.

  • Find the AED nearest to your home, school and gym, and note exactly where it is kept.
  • Practise the rhythm: compress a firm cushion at 100 to 120 per minute using a metronome app for two minutes, and notice how tiring it is.
  • Look up a certified CPR or basic life support course you could join in the next few months, and book it if you can.

Remember

  • No response and not breathing normally: call 998, start CPR, send for an AED.
  • Middle of the chest, 5 to 6 cm deep, 100 to 120 per minute.
  • Hands-only CPR is fine if you are not trained in rescue breaths.
  • Switch on the AED and follow its voice; nobody touches during analysis or shock.
  • Swap rescuers every one to two minutes if you can.
Note: This lesson is general information, not a substitute for a certified first aid course with hands-on practice. In the UAE, the Emirates Red Crescent runs first aid training (for example with universities), and in 2022 Abu Dhabi Police's Directorate of Emergency and Public Safety offered CPR, basic life support and AED courses through the TAMM portal for people over 16; check current dates and fees directly, or look for an accredited provider near you. Most step-by-step guidance here comes from UK bodies (St John Ambulance, NHS, British Red Cross), which say 'call 999 or 112'. In the UAE, 999 is police: for a medical emergency call 998 (ambulance), as listed on the UAE Government Portal. Numbers follow Resuscitation Council UK and St John Ambulance. The American Heart Association teaches Hands-Only CPR as two steps, 'call 911 and push hard and fast'; its exact depth and rate figures could not be fetched for this lesson, so UK figures are used throughout. Children and babies need different CPR techniques, which a course will teach. Dubai AED figures are from a January 2022 announcement and may have changed.

Check yourself

1. What compression rate do St John Ambulance and Resuscitation Council UK recommend for adult CPR?

2. How deep should adult chest compressions be?

3. If you are trained and willing to give rescue breaths, what is the ratio?

4. You are alone with a person in cardiac arrest and have no helper. What does St John Ambulance advise about the AED?

5. Where does one adult AED pad go?
