Objective: To determine whether real-time video communication between the first responder and a remote intensivist via Google Glass (GG) improves the management of a simulated inhospital pediatric cardiopulmonary arrest (pCPA) before the arrival of the intensive care unit team.Design: Randomized controlled study.Setting: Children's hospital at a tertiary care academic medical center.Subjects: 42 first-year pediatrics residents.Interventions: Pediatrics residents were evaluated during two consecutive simulated pCPAs with a high-fidelity manikin. During the second evaluation, the residents in the GG group were allowed to seek help from a remote intensivist at any time, by activating real-time video communication. The residents in the control group were asked to provide usual care.Measurements and Main Results: The main outcome measures were the proportion of time for which the manikin received no ventilation (no-blow fraction) or no compression (no-flow fraction). In the first evaluation, overall no-blow and no-flow fractions were 74% and 95%, respectively. During the second evaluation, no-blow and no-flow fractions were similar between the two groups. Insufflations were more effective (p=0.04) and the technique (p=0.02) and rate (p<0.001) of chest compression were more appropriate in the GG group than in the control group.Conclusions: Real-time video communication between the first responder and a remote intensivist through GG did not decrease no-blow and no-flow fractions during the first five minutes of a simulated pCPA, but improved the quality of the insufflations and chest compressions provided.3
