Summary

This study looks at how much pain people feel after a cardiac arrest while they are in the intensive care unit. Researchers will track pain using special scales, even in patients who are unconscious or on a breathing machine. The goal is to understand how pain affects recovery, such as time on a ventilator or in the ICU. About 300 adults who had a cardiac arrest outside the hospital and are still unconscious will take part.
