Cardiac Arrest (CA)NCT06794398
Feasibility of Appropriate Smartphone Position During Video-assisted Cardiopulmonary Resuscitation
A study testing V-CPR inside a room when the lay responder is alone (no operator for holding the phone) and V-CPR in a yard (outside environment) when the lay responder is alone (no operator for holding the phone) in people with Cardiac Arrest (CA), run by University of Pecs at 1 site in Hungary.
Trial summary
There is a gap in our knowledge regarding whether video-assisted cardiopulmonary resuscitation (V-CPR) is feasible when a lay responder is alone at the scene. The feasibility of V-CPR was measured in a simulated cardiac arrest scenario when a lay responder was alone with the patient. Read more about this study

About this study
Official title: Feasibility of Appropriate Smartphone Position During Video-assisted Cardiopulmonary Resuscitation When the Bystander is Alone At the Scene - a Randomized Controlled Crossover Simulation Trial
There is a gap in our knowledge regarding whether video-assisted cardiopulmonary resuscitation (V-CPR) is feasible when a lay responder is alone at the scene. The feasibility of V-CPR was measured in a simulated cardiac arrest scenario when a lay responder was alone with the patient.
Read the detailed description
There is a gap in our knowledge regarding whether video-assisted cardiopulmonary resuscitation (V-CPR) is feasible when a lay responder is alone. The feasibility of V-CPR was measured in a simulated cardiac arrest scenario when a lay responder was alone with the patient. A pilot study was conducted to measure the appropriate smartphone position and placement time when a lay responder is alone. Two simulated cardiac arrest locations were prepared: a living room and yard.
The performance of the participants were recorded. After that, the quality and assessability of the videos were evaluated by five experts (experienced in CPR teaching and evaluation).
- Conditions
- Cardiac Arrest (CA)
- Being tested

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
V-CPR inside a room when the lay responder is alone (no operator for holding the phone)Device
Participants should find an appropriate smartphone position when they were able to use any objects in their environment. Participants get video-based (vocal and visual) instructions from the dispatcher during the V-CPR situation.
V-CPR in a yard (outside environment) when the lay responder is alone (no operator for holding the phone)Device
Participants should find an appropriate smartphone position when they were able to use any objects in their environment. Participants get video-based (vocal and visual) instructions from the dispatcher during the V-CPR situation.
| Study group | Role | What they receive |
|---|---|---|
| V-CPR in the room | Experimental | Participants should perform a simulated V-CPR scenario based on the European Resuscitation Council 2021 Guidelines in a prepared room (inside environment). Receives: Device: V-CPR inside a room when the lay responder is alone (no operator for holding the phone); Device: V-CPR in a yard (outside environment) when the lay responder is alone (no operator for holding the phone) |
| V-CPR outside | Experimental | Participants should perform a simulated V-CPR scenario based on the European Resuscitation Council 2021 Guidelines in a prepared yard (outside environment). Receives: Device: V-CPR inside a room when the lay responder is alone (no operator for holding the phone); Device: V-CPR in a yard (outside environment) when the lay responder is alone (no operator for holding the phone) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Smartphone camera placement and perspective (used objects and visible environment)
Evaluating the used object (chair, table, shue, etc) to stabilize the smartphone for V-CPR in the prepared environment (a photo was taken by the study operator).
Evaluating smartphone camera perspective by the dispatcher's laptop screen (smartphone camera picture was transferred via Microsoft Teams from the smartphone to the laptop during a live video-stream (to see what the dispatcher did see). Live video-stream was also recorded for post-analysis.
Measured: During procedure
Secondary outcomes (1)
Smartphone camera placement time (time to the first chest compression)
Measuring the time from the dispatcher's instructions to the first chest compression (putting the hand on the patient's chest) based on the recorded video.
Measured: During procedure

Questions about this trial
What is this clinical trial studying?
A study testing V-CPR inside a room when the lay responder is alone (no operator for holding the phone) and V-CPR in a yard (outside environment) when the lay responder is alone (no operator for holding the phone) in people with Cardiac Arrest (CA), run by University of Pecs at 1 site in Hungary.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 27 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Hungary. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Smartphone camera placement and perspective (used objects and visible environment) (time frame: During procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06794398, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jan 2025.
