Cpr Survival Rate Statistics

GITNUXREPORT 2026

Cpr Survival Rate Statistics

Bystander CPR is linked to sharp survival differences, including a 40% alive at 1 month outcome in the ARREST trial and an increase in survival to discharge from 2% to 6% in a large Utstein-based study, plus modern system guidance that targets 100 to 120 compressions per minute and at least 5 cm depth. This page connects those results to real-world adoption rates and outcomes, showing what happens when CPR is actually delivered versus when it is not.

Bystander CPR survival odds can swing dramatically, yet most people still never see what those differences look like in real registries. In the CARES data, 13.6% of people who received bystander CPR survived to hospital discharge compared with just 3.1% without it, and the gap is even larger in some studies where dispatcher help or early defibrillation is involved. Let’s walk through the CPR survival rate statistics that explain not only how often bystanders act, but how that timing and quality changes outcomes.

Performance Metrics Interpretation

Across multiple studies, survival after out-of-hospital cardiac arrest rises when bystanders act, with odds and outcomes often roughly doubling, and some datasets showing jumps from about 2% baseline survival to as high as 15% when bystander CPR is combined with early defibrillation.

Market Size Interpretation

Even though about 4.5 million people worldwide experience out-of-hospital cardiac arrest each year, only 46.7% of U.S. cases receive bystander CPR, suggesting that improving early action could help prevent many of the roughly 200,000 preventable cardiac arrest deaths in the United States each year.
