Accuracy of Doppler Ultrasound Versus Manual Palpation of Pulse in Cardiac Arrest

Study Overview
=================
Brief Summary
-----------------
The FloPatch FP120 device is indicated for use for the noninvasive assessment of blood flow in the carotid artery. The FloPatch FP120 device uses ultrasound and the Doppler effect to non-invasively assess the flow of flood. In this study, the FloPatch FP120 will be applied to the neck at the location of the carotid artery on cardiac arrest patients in the emergency department. FloPatch FP120 data will be compared with arterial line blood pressure to assess for accuracy of pulse checks among cardiac arrest patients in the emergency department.

Detailed Description

The FloPatch FP120 device is indicated for use for the noninvasive assessment of blood flow in the carotid artery. The FloPatch FP120 device uses ultrasound and the Doppler effect to non-invasively assess the flow of flood. In this study, the FloPatch FP120 will be applied to the neck at the location of the carotid artery on cardiac arrest patients in the emergency department. This study will determine the peak systolic velocity, as measured by the FLoPatch FP120 device, that is associated with a systolic blood pressure of ≥60 mmHg on a femoral arterial line in cardiac arrest patients during a pulse check. The associated accuracy, sensitivity, and specificity of the calculated pulse systolic velocity to detect return of spontaneous circulation with a systolic blood pressure ≥60 mmHg in cardiac arrest.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Patients with Return of Spontaneous Circulation | Any patient achieving any episode of return of spontaneous circulation during a pulse check will be considered as having the outcome. Cardiac arrest resuscitations are typically not longer than 30 minutes. | 30 minutes |
