Brief 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.
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).
Interventions
DEVICEV-CPR inside a room when the lay responder is alone (no operator for holding the phone)
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.
DEVICEV-CPR in a yard (outside environment) when the lay responder is alone (no operator for holding the phone)
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Smartphone camera placement and perspective (used objects and visible environment) | During procedure | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Smartphone camera placement time (time to the first chest compression) | During procedure | 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. |
Other
| Measure | Time frame | Description |
|---|---|---|
| General quality of the video-records (clarity, lagging, camera perspective, visibility of chest compressions; by using a Likert-scale: from 1 - very bad quality to 4 - very good quality) | During post-analysis of the video-records (within 1 week after data collection) | Measuring the general quality of the video-records (Is chest compression depth, rate and hand position visible?; clarity and lagging of the video-record) based on the assessors subjective answers by using a Likert-scale: from 1 - very bad quality to 4 - very good quality). |
