Pulse Detection in Cardiac Arrest Patients Using a Doppler Ultrasound Patch on the Carotid Artery

Heartstream US LLC20 enrolled

Overview

The purpose of this study is to find out if a Doppler ultrasound patch placed on the neck can accurately and quickly detect when a cardiac arrest patient's heart starts beating again (return of spontaneous circulation, or ROSC) during resuscitation in the emergency department. The study compares the ultrasound readings to data from an arterial line, which is considered the most reliable way to check for a pulse. The main question the study is trying to answer is whether using Doppler ultrasound is better than the traditional method of feeling for a pulse, which can be unreliable, especially in stressful situations. Secondarily, this study aims to assess blood flow through the carotid artery from chest compressions during resuscitative events to determine overall effectiveness. This research hopes to show that Doppler ultrasound can help medical teams recognize when a patient's heart has restarted more accurately and quickly, leading to better care during cardiac arrest.

Conditions

Cardiac Arrest (CA)Return of Spontaneous Circulation CPR Quality Assessment

Interventions

A Doppler ultrasound patch will be placed on the patient's neck over the carotid artery to continuously record blood flow during resuscitation. For patients who already have an arterial line as part of their regular care, whether a pulse is present or not will also be recorded at each pulse check. No arterial lines will be inserted just for this study. There is no change to patient care.

Medical Language ↔ Plain English

Inclusion Criteria: * Any adult patient aged \> 18 to 99 years old * Intact skin on their neck * In cardiac arrest with an arterial line placed during the resuscitation event as part of the standard of care. Exclusion Criteria: * Patients in cardiac arrest with a Do Not Resuscitate/Do Not Intubate (DNR/DNI) order. * Patients without an arterial line in place as part of the standard of care. * \*Pregnant women * \*Prisoners * Any data from these two populations (pregnant/prisoner) will not be downloaded at all if it is discovered post-resuscitation event that the patient is pregnant and/or a prisoner.

Outcomes

Primary Outcomes

Accuracy of Doppler Ultrasound Patch for Detecting Return of Spontaneous Circulation During Cardiac Arrest

Evaluate how well the Doppler ultrasound patch can detect when a cardiac arrest patient's heart starts adequately beating again, by comparing its results to blood pressure readings from an arterial line.

Time frame: Periprocedural

Secondary Outcomes

Association Between Doppler Ultrasound Patch Waveforms and Chest Compression Quality During Cardiac Arrest

Determine if the Doppler ultrasound patch readings on the neck during chest compressions match up with measures of chest compression quality, using data from the cardiac monitors.
