Doppler Ultrasound Patch for Pulse Detection in Cardiac Arrest

This study is looking at whether a Doppler ultrasound patch, placed on your neck over the carotid artery, can accurately and quickly tell if your heart has started beating again (Return of Spontaneous Circulation, or ROSC) during a cardiac arrest. This is an observational study, meaning you won't receive any new treatments. Researchers will compare the ultrasound readings to information from an arterial line, which is a standard way to check for a pulse. The goal is to see if this patch is better than feeling for a pulse, which can be difficult. The study also aims to see how well blood flows through the carotid artery during chest compressions. This study plans to enroll 20 adults, aged 18-99, who are in cardiac arrest and already have an arterial line as part of their regular care. The study's status is currently unclear.

Study design
This is an observational study involving 20 adult participants. It aims to compare a Doppler ultrasound patch to an arterial line for detecting pulse during cardiac arrest.
What's involved
A Doppler ultrasound patch will be placed on your neck during resuscitation. If you have an arterial line, whether a pulse is present will also be recorded at each pulse check.
Compensation
Not stated in the trial record.
Follow-up
The primary endpoint is measured periprocedurally, meaning during the procedure itself.

Eligibility criteria

Inclusion

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

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.

What this trial measures

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

    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.
