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
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 This study
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 Results may not be published yet.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.

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.

Summary

This study tested whether video calls with emergency dispatchers help bystanders perform CPR better than phone-only instructions, especially in tough conditions like darkness. 157 healthy volunteers managed a simulated cardiac arrest alone, with some using video and others just a phone. Researchers measured chest compression depth, rate, and hand position to see if video guidance improves quality.

What this could mean

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

What this could lead to
If video-assisted CPR proves better than phone-only instructions, it could improve survival from cardiac arrest by helping bystanders perform higher-quality chest compressions.
What could go wrong
This was a simulation study with healthy volunteers, not real emergencies. Real-world distractions and stress may change results, and video calls could delay starting CPR.
