Can we trust resuscitation rules in asia? huge study aims to find out
NCT ID NCT05545176
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at rules doctors use to decide when to stop trying to revive someone after a cardiac arrest outside the hospital. These rules were made in Western countries, and this study checks if they work for people in Asia. Researchers will study 140,000 patients to see if the rules are accurate and may create new ones that fit Asian populations better.
