Breath of life: CO2 readings may predict cardiac arrest survival
NCT ID NCT07632430
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether the amount of carbon dioxide a person breathes out during CPR can help predict if they will survive a cardiac arrest that happens outside a hospital. Researchers are reviewing records from 3,500 adults who had a cardiac arrest and were treated by emergency services. The goal is to find which CO2 patterns are most strongly linked to survival and good brain function after discharge.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help paramedics better predict which patients might survive cardiac arrest, guiding more informed treatment decisions.
What could go wrong
This is an observational study, not a treatment trial. It may not find a clear link between CO2 levels and survival, and results may not apply to all settings.
