Could Hands-Only CPR be just as good as standard CPR?
NCT ID NCT03981107
First seen May 11, 2026 · Last updated Jun 22, 2026 · Updated 5 times
Summary
This study compares two types of CPR for people who have a cardiac arrest outside a hospital: hands-only CPR (chest compressions without rescue breaths) versus standard CPR (compressions plus rescue breaths). The trial will include over 3,000 adults whose cardiac arrest is witnessed and who have a bystander with prior CPR training. The goal is to see if hands-only CPR is at least as effective as standard CPR at helping people survive for 30 days.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Chest compression only CPR (hands-only CPR)
What this could lead to
If hands-only CPR works as well as standard CPR, it could simplify training and encourage more bystanders to act, potentially saving more lives from cardiac arrest.
What could go wrong
This is a large trial, but it only includes trained bystanders and witnessed arrests. Results may not apply to all situations, and hands-only CPR might be less effective for certain causes of cardiac arrest.
