how long should you conduct cpr

You should continue CPR until one of a few clear things happens: the person starts to move/breathe normally, a defibrillator or professional help takes over, you are physically unable to continue, or you are in danger yourself.

Key answer (simple)

In a real emergency, bystanders are generally taught to keep doing CPR without stopping until :

• The person shows signs of life (normal breathing, movement, coughing).

• A healthcare professional, paramedic, or trained responder tells you to stop or takes over.

• An AED (defibrillator) is ready to use and you pause only as directed by the device.

• You are too exhausted to continue or the scene becomes unsafe.

In hospitals, studies and guidelines discuss durations like 20–40 minutes or more, but these decisions are made by medical teams, not lay rescuers.

How long should you conduct CPR?

For a layperson (non‑professional) rescuer:

• Start CPR as soon as you recognize cardiac arrest (unconscious, not breathing normally).

• Keep going with chest compressions at 100–120 per minute until help arrives or the person revives.

• Do not stop just because “it’s been a while”; good outcomes have been reported even after 30–40 minutes of resuscitation in some cases, especially with professional care.

For healthcare teams, research suggests:

• Many patients who recover with good brain function achieve return of spontaneous circulation (ROSC) within about 15–20 minutes, but not all.

• Several large studies suggest that continuing efforts for 30–45 minutes (and sometimes longer in selected cases) can still lead to survival with acceptable neurological outcomes, so prolonged CPR is not automatically futile.

Practical rules for bystanders

If you are a bystander, think less in minutes and more in clear stopping conditions :

1. Start CPR immediately
   • Check responsiveness and breathing.
   • If not breathing normally, call emergency services and begin compressions.

2. Keep compressing until :
   • The person breathes normally, moves, or wakes up.

 * Emergency medical services arrive and take over.

 * An AED says “stop” for analysis or “no further shocks advised” _and_ professionals take over.

 * You are physically unable to continue due to exhaustion.

3. Do not give up early just because it feels “too long”
   • Research shows survivors even after 30+ minutes of ongoing CPR, especially in settings with advanced care.

Why you often hear “don’t stop”

Many real‑life forum stories and discussions highlight how emotionally intense it feels to do CPR for a long time, especially when the outcome is uncertain. People often underestimate how long they’ve actually been performing compressions because adrenaline distorts their sense of time.

Because of that, modern public guidance leans toward: “Start CPR and don’t stop until help arrives or the person clearly recovers.” This simple message is easier to remember in a crisis than a specific minute count.
