Interactive videoconferencing versus audio telephone calls for dispatcher-assisted cardiopulmonary resuscitation using the ALERT algorithm: a randomized trial

Objectives: The ALERT algorithm, a telephone cardiopulmonary resuscitation (CPR) protocol, has been shown to help bystanders initiate CPR. Mobile phone communications may play a role in emergency calls and improve dispatchers’ understanding of the rescuer’s situation. However, there is currently no validated protocol for videoconference-assisted CPR (v-CPR). We initiated this study to validate an original protocol of v-CPR and to evaluate the potential benefit in comparison with classical telephone-CPR (t-CPR). Materials and methods: We developed an algorithm for v-CPR, adapted from the ALERT t-CPR protocol. A total of 180 students were recruited from secondary school and assigned randomly either to t-CPR or to v-CPR. A manikin was used to evaluate CPR performance. Results: The mean chest compression rate was higher in the v-CPR group (v-CPR: 110±16 vs. t-CPR: 86±28; P
