Lauridsen KG, et al. - Given a lack of recommendations for standardized communication to reduce chest compression (CC) pauses, researchers sought to achieve consensus and appraise feasibility and efficacy using standardized communication during cardiopulmonary resuscitation (CPR) events. They adopted the modified Delphi consensus process in order to design standardized communication elements. They tested the feasibility in 16 simulated CPR scenarios (8 scenarios with physician team leaders and 8 with chest compressors) randomized (1:1) to standardized [INTERVENTION] vs closed-loop communication [CONTROL]. For standardized communication, included consensus elements were: 1) team preparation 15−30 s before CC interruption, 2) preinterruption countdown synchronized with last 5 CCs, 3) specific action words for defibrillation, intubation, and interrupting/resuming CCs. Consensus-based standardized communication was correlated with shorter CC pauses for defibrillation, intubation, and rhythm checks without raising frustration index or mental demand compared with current best practice, closed loop communication.
