Evaluation of Efficacy of the Prototype RPC (Rapid Pulse Confirmation)

Status Completed

Clinical Trial Summary

Effective chest compressions are essential to survival in an arrest patient receiving CPR (cardiopulmonary resuscitation). A challenge in providing effective chest compressions is frequent interruption of compressions. A major cause of a recurrent interruption of chest compressions is pulse checks. Pulse checks are difficult to quickly and accurately perform in the AHA recommended time interval of under 10 seconds for reasons ranging from inexperience to body habitus. Unnecessarily long pulse checks often delay reinitiating chest compressions leading to a fall in perfusion pressure to the coronary arteries lowering the chances of return of spontaneous circulation (ROSC). To potentially solve the issues of evaluating the chest compression effectiveness and minimize the time interval of pulse checks, the authors have constructed a novel device that can be rapidly applied to an arresting patient and evaluate the current state of the circulatory system. The device is called the Rapid Pulse Confirmation (RPC) device. It is designed to applied over a major artery (radial, ulnar, brachial, carotid, and femoral) and detect Doppler shift of red blood cells to gauge red blood cell velocity and rate of pulsation. Feasibility testing on the device was carried out using patients requiring cardiopulmonary bypass. Arrest and return of spontaneous circulation during cardiopulmonary bypass is predictable and provided an ideal environment to test the initial performance of a device meant to detect return of spontaneous circulation. The primary working hypothesis was that there would be no significant difference in time of detection of ROSC between the arterial line catheter and the RPC device at the end of cardiopulmonary bypass. The secondary hypothesis was that there would be no difference in pulse rate reading between the arterial line catheter and the RPC device.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
