Brief Summary

The aim of the study is to analyse if live video as a supplement to emergency calls can improve medical dispatchers' situation awareness and enhance the assistance they provide including provision of pre-hospital resources. Focus will also be on evaluating the unconscious patient and improve CPR quality. The general experience from the medical dispatcher and the person calling the emergency number regarding the feasibility of adding live video will also be analysed.

Outcome Measures

Primary Outcomes (9)

• Changed emergency response after adding live video to the emergency call

  Did the medical dispatcher change emergency response more often after live video was added to the emergency call compared to emergency calls without video.

  From the beginning of the emergency call to the end of the call. Approx. 6-7 minutes

• The medical dispatcher's evaluations of the patient after adding live video footage to the emergency call.

  Did the medical dispatcher's evaluation of the patient change because of the live video footage? (ANSWER: Yes, patient more critical ill/ Yes, less critical ill/ or no change) Did the patient suffer another trauma/disease compared to what the medical dispatcher thought before the live video footage? (ANSWER: No/Yes (describe)).

  From the beginning of the emergency call to the end of the call. Approx. 6-7 minutes

• The medical dispatcher's evaluations of the patient's level of consciousness before and after adding live video footage to the emergency call.

  The medical dispatcher evaluate the patient's level of consciousness before and after the live video footage; AVPU scale (an acronym from "alert, verbal, pain, unresponsive") /or inaccessible.

  From the beginning of the emergency call to the end of the call. Approx. 6-7 minutes.

• The medical dispatcher's evaluations of the surroundings and bystander response after adding live video footage to the emergency call.

  Did the medical dispatcher situation's awareness regarding the surroundings or bystander response change after video footage? (ANSWER: No/ Yes, Less bystanders present/ Yes, more bystanders present/ Yes, bystander response were more sufficient/ Yes, bystander response were less sufficient/Yes, surroundings were different(describe)/ other (describe)).

  From the beginning of the emergency call to the end of the call. Approx. 6-7 minutes.

• The medical dispatcher's evaluations of the usefulness of adding live video footage to the emergency call.

  Was the live video footage useful for the medical dispatcher"? (ANSWER: Extremely useful/ very useful/ moderately useful/ slightly useful/ not at all useful).

  From the beginning of the emergency call to the end of the call. Approx. 6-7 minutes.

• Change in emergency level after adding live video footage to the emergency call.

  Did the medical dispatcher change emergency priority level because of the live video footage?" (ANSWER: No, Yes (upgrade, downgrade))

  Evaluated at the end of the emergency call.

• Change in the CPR quality (hand position) before the medical dispatcher assist in CPR using the video footage (video-DA-CPR) and after the medical dispatcher has assisted .

  Correct hand position before and after video-DA-CPR? (Outcome: yes / no / inaccessible evaluated before and after video-DA-CPR)

  From the medical dispatcher receive video footage until the end of video-DA-CPR.

• Change in the CPR quality (compressions rate) before and after video-DA-CPR.

  Correct compressions rate (100-120 compressions/min) before and after video-DA-CPR (Outcome: yes / no / inaccessible evaluated before and after video-DA-CPR)

  From the medical dispatcher receive video footage until the end of video-DA-CPR.

• Change in the CPR quality (compressions depth) before and after video-DA-CPR

  Correct compressions depth before and after video-DA-CPR (approximately one third of the anterior-posterior diameter). (Outcome: yes / no / inaccessible evaluated before and after video-DA-CPR)

  From the medical dispatcher receive video footage until the end of video-DA-CPR.

Secondary Outcomes (6)

• "Hands-of-time" during CPR

  From the medical dispatcher receive video footage until the end of the call. Approx. 5-6 minutes.

• Ventilations performed by bystanders?

  From the medical dispatcher receive video footage until the end of video-DA-CPR.

• Shift of persons during CPR

  From the medical dispatcher receive video footage until the end of the call. Approx. 5-6 minutes.

• Use of AED

  From the medical dispatcher receive video footage until the end of the call. Approx. 5-6 minutes.

• Other aspects of bystander CPR

  From the medical dispatcher receive video footage until the end of the call. Approx. 5-6 minutes.
