Resuscitation Outcomes Consortium (ROC) Prehospital Resuscitation Using an Impedance Valve

Stopped early · Phase 3 · Has a placebo group

Conditions studied: Heart Arrest

In brief

The purpose of this study is to look at two different treatments during a cardiac arrest that occurs outside of the hospital and whether either or both treatments will increase the number of people who live to hospital discharge. A cardiac arrest is when the heart stops pumping blood to the body.
