Resuscitation Outcomes Consortium (ROC) Prehospital Resuscitation Using an Impedance Valve and Early Versus Delayed Analysis
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.
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.
The first treatment involves using a device called the Impedance Threshold Device (ITD). The
ITD is a small hard plastic device about the size of a fist that is attached to the face mask
or airway tube used during CPR (cardiopulmonary resuscitation). The ITD provides increased
blood flow back to the heart during chest compressions until the heart starts beating on its
own again.
The other treatment involves the amount of CPR given before the emergency medical services
(EMS) providers first look at the heart rhythm to determine if a shock is needed. A person
would receive either about 30 seconds of chest compressions or about 3 minutes of
compressions before checking the heart rhythm. Giving some compressions before checking the
heart rhythm increases the blood being circulated to the body. Researchers do not know how
many compressions before the rhythm check are necessary to save more lives.
Depending on the circumstances of the cardiac arrest a person may receive only one of these
treatments or both of these treatments. The purpose of the research study is to determine if
more people live when either the real ITD is used or if additional CPR is given before
looking at the heart rhythm the first time. This study is being conducted in 9 different
areas throughout the United States and Canada by the Resuscitation Outcomes Consortium (ROC).
About 15,000 patients will be enrolled in this research study.

Inclusion Criteria:
- All persons of local age of consent or older who suffer non-traumatic cardiopulmonary
arrest outside of the hospital in the study communities with defibrillation and/or
delivery of chest compressions provided by emergency medical service (EMS) providers
dispatched to the scene and do not meet any of the exclusion criteria.
Exclusion Criteria:
Common:
- Do not attempt resuscitation (DNAR) orders
- Blunt, penetrating, or burn-related injury
- Patients with exsanguinations
- Known prisoners
- Known pregnancy
- Non-ROC EMS agency/provider
For Analyzing Late versus Early
- EMS-witnessed arrests
- Non-EMS rhythm analysis (AED placed by police or lay responder is an exclusion but CPR
by lay or other non-EMS responders is not)
For ITD:
- Tracheostomy present
- CPR performed with the mechanical compression "Autopulse" device.
