About

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.

Full 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.

Trial design

35 participants in 2 patient groups

Patients achieving return of spontaneous circulation

Description:

All patients in cardiac arrest with an arterial line in place in the emergency department will be a potential subject. The FloPatch FP120 device will be placed on patients and the carotid artery peak systolic velocity associated with a systolic blood pressure ≥60 mmHg on a femoral arterial line during a pulse check will be determined.

Treatment:

Device: FloPatch FP120

Patients not achieving return of spontaneous circulation

Description:

All patients in cardiac arrest with an arterial line in place in the emergency department will be a potential subject. The FloPatch FP120 device will be placed on patients and the carotid artery peak systolic velocity associated with a systolic blood pressure ≥60 mmHg on a femoral arterial line during a pulse check will be determined.
