Comparing Doppler Ultrasound and Manual Pulse Checks in Cardiac Arrest

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

Observational Northwell Health · NCT05558228

This study is testing a new device that uses ultrasound to check blood flow in the neck of cardiac arrest patients to see if it can accurately tell when their heart starts beating again.

What this trial studies

This study evaluates the accuracy of the FloPatch FP120 device, which uses Doppler ultrasound to assess blood flow in the carotid artery, in cardiac arrest patients. The device will be applied to the neck of patients in the emergency department, and its data will be compared to arterial line blood pressure measurements. The goal is to determine the peak systolic velocity that correlates with a systolic blood pressure of ≥60 mmHg, assessing the device's accuracy, sensitivity, and specificity in detecting return of spontaneous circulation.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are in cardiac arrest and have an arterial line placed during resuscitation.

Not a fit: Patients with traumatic cardiac arrest or those without bilateral lower extremities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of pulse checks in cardiac arrest patients, potentially leading to better outcomes.

How similar studies have performed: While the use of Doppler ultrasound in this context is innovative, similar studies have shown promise in improving noninvasive assessments of blood flow.
