Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether performing active compression decompression cardiopulmonary resuscitation (ACD-CPR) with an impedance threshold device (ITD) compared to conventional standard cardiopulmonary resuscitation (S-CPR) will impact the neurologic recovery and survival to hospital discharge following out-of-hospital cardiac arrest.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Despite receiving conventional, standard CPR (S-CPR), most patients who experience out-of-hospital cardiac arrest die prior to arriving at a hospital. At the present time, the hospital discharge rate following out-of-hospital, nontraumatic cardiac arrest in adults in the United States is estimated to be less than 5%. Many factors contribute to the current poor survival statistics, including the inefficiency of the technique itself. CPR provides only 10% to 20% of normal myocardial perfusion, and only 20% to 30% of physiologically normal cerebral perfusion.

A new method of CPR that combines ACD and an ITD (ACD-CPR+ITD) has been shown in animal models and in clinical trials conducted in Europe to provide significantly more blood flow to the vital organs and to improve survival rates when compared to S-CPR or ACD-CPR alone.

ACD-CPR+ITD works by decreasing intrathoracic pressure during the chest wall recoil (or decompression) phase of CPR, creating a vacuum within the thorax relative to the rest of the body. When compared with controls, use of ACD-CPR+ITD (a) enhances blood return to the thorax during the chest wall recoil phase, (b) enhances blood flow to the heart and brain, (c) provides real-time feedback to rescuers to maintain high-quality CPR, (d) improves overall CPR efficiency and, as a result of the forgoing, (e) improves short-term survival rates.

The sponsor and others recently evaluated the effectiveness of the combination of conventional, manual standard CPR±ITD in animals and humans. The ITD increased short-term survival rates in these studies as well. Two clinical trials were performed in Milwaukee, Wisconsin, under IDE (#G980125). Both compared S-CPR with either a sham (nonfunctional or placebo) or active (functional) ITD. The results from the hemodynamic study demonstrated that systolic blood pressure, the primary end point, increased from approximately 45 mmHg with the sham ITD to approximately 85 mmHg with the active ITD (P less than 0.05). Intensive care unit admission rate was the primary end point of the clinical outcome study.

Comparisons: The objective of this two-arm, multisite, randomized, pivotal IDE clinical trial is to compare survival to hospital discharge with neurologic recovery rates in subjects receiving S-CPR compared to ACD-CPR+ITD following out-of-hospital cardiac arrest in well-established American emergency medical services systems.

Intervention Type DEVICE

The ITD selectively prevents the influx of unnecessary respiratory gases into the patient during the chest wall recoil phase of CPR.

The ResQPump, a hand-held device containing a suction cup, attaches to the chest and actively compresses and actively re-expands the chest during the performance of CPR.
