With bystander CPR adoption swinging from 2.3-fold higher odds of survival to hospital discharge in observational data to survival-to-discharge rates of just 0.3% without it in the ARREST trial control group, these CPR survival rate statistics make one question unavoidable which details can help you save the next life.
Key Takeaways
- 8.6% of out-of-hospital cardiac arrests in North Carolina were treated with bystander CPR (2007–2010 data).
- 6.2% of out-of-hospital cardiac arrests in North Carolina received bystander CPR (2002–2005 data).

Industry Trends
1Survival after out-of-hospital cardiac arrest in the US is 10.1% overall (AHA 2024 updates cite CARES/registry estimates).[20]
Verified2In the US, bystander CPR rates increased to 56% of out-of-hospital cardiac arrest cases (AHA 2024 reporting).[20]
Verified3In the US, public-access defibrillation (PAD) rates were estimated at 7% of out-of-hospital cardiac arrest cases (AHA 2024 reporting).[20]
Verified4EuReCa ONE reported a bystander CPR rate of about 45% in Europe (cross-country estimate).[21]
Directional5In Sweden, bystander CPR rates were reported around 60% in the Resuscitation outcomes survey.[22]
Single source6Japan’s witnessed out-of-hospital cardiac arrest survival rates are higher in systems with rapid EMS response and bystander action (reported discharge survival ~10% in national reports).[23]
Verified7China’s bystander CPR rates were reported as low (single digits) in early registry analyses; survival after OHCA varied widely (average discharge survival ~1%–2%).[24]
Verified8The AHA reported that about 356,000 out-of-hospital cardiac arrests occur annually in the US and fewer receive bystander CPR.[25]
Verified9The AHA estimated that only 39% of out-of-hospital cardiac arrest victims receive bystander CPR in the US (older national estimate referenced in AHA materials).[26]
DirectionalIndustry Trends Interpretation
Despite an overall 10.1% out-of-hospital cardiac arrest survival in the US, only about 39% receive bystander CPR while just 7% get public-access defibrillation, showing that small improvements in early public action could drive major gains.
Market Size
1The global incidence of out-of-hospital cardiac arrest is estimated around 4.5 million cases per year (systematic estimate).[27]
Verified2The global incidence of sudden cardiac arrest is estimated around 3.4 million cases per year (systematic estimate).[28]
Verified3In a US analysis using CARES data, 21.6% of OHCA cases had a witnessed arrest.[29]
Verified4In the same CARES-based analysis, 46.7% of OHCA cases were treated with bystander CPR.[29]

Single source6AHA estimated 200,000 annual cardiac arrest deaths in the US that could be prevented by improved systems (AHA policy context).[31]
VerifiedMarket 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.
Cost Analysis
1Global AED market size is projected to reach $5.6B by 2028 (relevant to public-access defibrillation and CPR outcomes).[32]

Verified4In a cost-effectiveness study, telephone CPR instructions cost about £1,000 per QALY gained (UK evaluation).[35]
Directional5In an economic model, public-access defibrillation programs can yield incremental cost-effectiveness ratios below $50,000 per QALY (US-style thresholds).[36]
Single source6In a hospital-based CPR program cost study, the cost per additional survivor was estimated at under $10,000 (economic evaluation).[37]
Verified7The cost of implementing community CPR training can be under $200 per person trained in published program budgets.[38]

Verified12In a US evaluation, CPR manikin-based training for laypersons averaged $48 per participant (program cost analysis).[43]
Verified13AHA training programs cite that skills retention after CPR training declines substantially within months, affecting program cost-benefit (retention time).[44]
Verified14Bystander CPR performance can drop after training; in a study, correct CPR performance declined from 70% immediately to 40% at 6 months (retention).[45]
Directional15When refreshed training is applied every 6–12 months, skills retention improves (policy evaluations cite improved performance).[46]
Single sourceCost Analysis Interpretation
Across multiple cost-effectiveness and training studies, CPR and dispatcher or AED support consistently look economically favorable, with cost per QALY often around £1,000 or €5,000 to €10,000 and some programs estimating the cost per additional survivor at under $10,000, while evidence also shows CPR skills can fall from 70% right after training to 40% at 6 months but improve when refreshers are repeated every 6 to 12 months.
