If you notice agonal breaths in an unresponsive patient, treat them as not breathing normally and act as if they are in cardiac arrest.

Quick Scoop: What To Do Immediately

Agonal breaths are abnormal, gasping, occasional breaths that often happen during sudden cardiac arrest, not “normal” breathing that can keep someone alive.

  1. Check quickly for responsiveness and breathing
    • Shake or tap the person and shout.
    • Look for normal breathing, not occasional gasps or snoring‐like breaths.
 * If they are unresponsive and only gasping, you must assume cardiac arrest.
  1. Call emergency services right away
    • Call 911 (or your local emergency number), or tell someone else to call while you stay with the patient.
    • Tell the dispatcher: “They are unresponsive and gasping / breathing abnormally.” This helps them recognize agonal breathing and coach you through CPR.
  1. Start CPR without delay
    • Place the person flat on their back on a firm surface.
    • Put the heel of one hand in the center of the chest, other hand on top.
    • Push hard and fast (about 100–120 compressions per minute, around 2 inches/5 cm deep in an adult), allowing the chest to fully recoil between compressions.
 * If you are not trained or are unsure, do **hands‑only CPR** (compressions only).

 * If trained, you can add 2 rescue breaths after every 30 compressions, but do not delay compressions to figure this out.
  1. Use an AED as soon as it’s available
    • Send someone to get an AED if one may be nearby (office, gym, airport, school, mall).
 * Turn it on, follow the voice prompts, attach pads, and **deliver a shock if advised**.
 * Resume chest compressions immediately after each shock or “no shock” message.
  1. Keep going until help takes over
    • Continue CPR and AED use until:
      • Emergency responders arrive and take over, or
      • The person starts to move, wake up, or breathe normally again.
 * Even if agonal gasps continue, do not stop CPR unless instructed by professionals or the person clearly recovers.

Why Agonal Breathing Is So Dangerous

  • Agonal breathing usually means severe lack of oxygen to the brain , often from cardiac arrest or stroke.
  • People frequently misinterpret these gasps as “they’re still breathing, so they don’t need CPR,” which can fatally delay life‑saving treatment.
  • Studies and training organizations emphasize that patients in cardiac arrest who show agonal breathing may actually have a better chance of survival if CPR and defibrillation start quickly.

A simple mental rule used in many modern CPR courses:

“Unresponsive + abnormal / gasping breaths = start CPR and call for help. ”

Mini Scenario (To Fix It In Your Mind)

You’re at work and a coworker suddenly collapses.
You find them on the floor, eyes open but not responding. Every 15–20 seconds, they give a strange gasping breath that sounds like someone gulping for air. They don’t answer when you shout their name, and the breathing looks wrong.

  • You shout for help and tell a colleague to call 911 and bring the AED.
  • You tell the dispatcher: “They are unresponsive and gasping ; it doesn’t look like normal breathing.”
  • You immediately start hard and fast chest compressions in the center of the chest.
  • When the AED arrives, you attach the pads and follow its instructions, continuing CPR until EMS takes over.

That sequence—Call, Push, Shock —is exactly what many current resuscitation campaigns teach for this situation.

Key Takeaway (TL;DR)

If you notice agonal breaths in an unresponsive patient, do not assume they are okay or “still breathing.”
Treat it as cardiac arrest: call emergency services, start CPR immediately, use an AED if available, and continue until help arrives or normal breathing returns.
