International Device Assisted Controlled Sequential Elevation CPR Registry

Study Overview
=================
Brief Summary
-----------------
The purpose of this prospective observational cardiopulmonary resuscitation (CPR) registry is to track the use and clinical outcomes from emergency medical systems across the US and Europe that have implemented a system of care approach applied rapidly to cardiac arrest that includes using the combination of an impedance threshold device (ITD), and either manual active compression-decompression (ACD) CPR device or automated compression device, with a Head Up CPR device.

Detailed Description
-----------------
In 2019, a FDA approved patient positioning device capable of elevating the head and thorax in a controlled manner became commercially available. As emergency medical services are increasingly using this Head Up CPR patient positioning device as part of their standard protocol for cardiac arrest patients, in addition to Active Compression-Decompression (ACD) cardiopulmonary resuscitation with an Impedance Threshold Device (ITD) CPR or with mechanical CPR and the ITD, it is important to monitor how this device is being used, and outcomes of patients who received this Head Up CPR therapy. All of the devices used in this observational registry study have received FDA 510K clearance. Emergency medical systems (EMS) that have implemented standard cardiac arrest protocols that include the combination of manual CPR with an ITD, an automated CPR device with the ITD, or ACD+ITD CPR, with the Head Up CPR device are asked to be part of the Registry. If a system participates, they are asked for de-identified cardiac arrest data including patient demographics, details of cardiac arrest care, and patient outcomes before and after implementation of the Head Up CPR bundle. De-identified data is kept securely by the study sponsor and PI. The patient data for all systems using this approach to resuscitation are included, with a current focus on patients receiving the device combination rapidly.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Head Up CPR based bundle of care<br>All patients in the registry receive the Head Up CPR based bundle of care. | Device: Head Up CPR based bundle of care<br>* All patients in this registry receive the intervention, a Head Up Cardiopulmonary Resuscitation (CPR) based bundle of care. This bundle of care includes the use of multiple FDA approved devices. The components of the Head Up CPR bundle are 1) a single or combination of CPR methods including manual, active-compression decompression CPR, or automated suction-cup based CPR 2) An impedance threshold device 3) An automated patient positioning device capable of elevating the head and thorax<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Return of Spontaneous Circulation | Presence of cardiac activity with a perfusing blood pressure | From the start of CPR to the presence of cardiac activity. The time period in which this outcome will varies and is estimated to range from 0 minutes up to around 40 minutes. | 
| Survival | If the patient survived admission to the hospital until hospital discharge | The time period in which this outcome will occur will vary, may extend up to 60 days. | 
| Survival with Favorable Neurological Function | If the patient survived admission to the hospital until hospital discharge with favorable Cerebral Performance Category (CPC) Score as defined CPC 1 or 2. | The time period in which this outcome will occur will vary, may extend up to 60 days. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| End tidal CO2 (ETCO2) | ETCO2 is an indirect measure of perfusion during CPR | ETCO2 will be measured continuously while the patient is receiving CPR. This time period is estimated to occur up to 40 minutes. | 
| Cerebral Oximetry | Near-infrared spectroscopy (NIRS) capable of measuring regional tissue oxygenation. | If the participating EMS system in the registry uses NIRS cerebral oximetry, it will be measured continuously while the patient is receiving CPR. This time period is estimated to occur up to 40 minutes. |
