A large review of observational data looked at nearly 3 million cases of out-of-hospital cardiac arrest. The study looked at whether people who received immediate CPR from bystanders had better chances of survival compared to those who did not.
Researchers found that patients who received bystander CPR had better outcomes. Specifically, there was a 26% increase in the odds of reaching the hospital, a 44% increase in the odds of being discharged from the hospital, and a 50% increase in the odds of surviving for 30 days.
It is important to note that these results come from observational studies, not a controlled trial. The benefits were less clear in studies involving older patients or a higher number of female patients. Because this is based on observational data, it shows a link rather than a direct cause.

Common questions
Does bystander CPR improve survival after cardiac arrest?
Yes, the data shows a link between bystander CPR and better outcomes. Patients who received bystander CPR had a 26% increase in the odds of reaching the hospital and a 50% increase in the odds of surviving for 30 days compared to those who did not receive it.
Who benefits most from bystander CPR?
The study found that the benefits of bystander CPR were less clear in cases involving older patients or a higher proportion of female patients. You should speak with a medical professional to understand how these findings apply to specific situations.
How much does bystander CPR improve hospital discharge rates?
The analysis showed that patients who received bystander CPR had a 44% increase in the odds of being discharged from the hospital. These findings are based on a review of observational studies involving nearly 3 million events.
