Two-way video calling improves the confidence of bystanders attempting to perform CPR in a medical emergency, according to new research.
The Norwegian study examined whether video phones in the hands of members of the public could be used to assess the condition of patients in an emergency and whether lay rescuers were more confident when they were instructed by video calling rather than audio alone.
The researchers conducted a series of 10-minute simulated emergencies involving 180 students in their late teens to assess whether visual contact and supervision improved their confidence.
Nurses at an emergency medical dispatch centre instructed the rescuers on how to proceed, using the video-link to remotely assess the patients’ condition and provide guidance.
The majority of rescuers confirmed that video calls were superior to audio calls alone, although some complained of poor sound quality.
