What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether a Doppler ultrasound patch placed on the neck can quickly and accurately detect when a cardiac arrest patient's heart starts beating again during emergency resuscitation. The patch's readings are compared to those from an arterial line, the gold standard for pulse detection. The study also explores whether the patch can assess blood flow from chest compressions to gauge CPR quality. If successful, this device could help medical teams recognize return of spontaneous circulation more reliably than manual pulse checks.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Doppler ultrasound patch placed on the carotid artery
What this could lead to
If it works, this could give emergency teams a faster, more reliable way to detect a restarting heart during cardiac arrest, potentially improving resuscitation outcomes.
What could go wrong
This is a small early-stage study with only 20 participants, so results may not apply broadly. The patch's accuracy in real-world chaotic settings remains unproven.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Any patient that comes into the University Hospital's Emergency Department displaying signs and symptoms of cardiac arrest may be considered for this effort. Only those patients that receive an arterial line as part of standard of care will be enrolled into the effort.

Ages

18 to 99 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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.
