Review Meta Analysis
Quality of audio-assisted versus video-assisted dispatcher-instructed bystander cardiopulmonary resuscitation: A systematic review and meta-analysis.
This study aimed to conduct a systematic review and meta-analysis comparing the effect of video-assistance and audio-assistance on quality of dispatcher-instructed cardiopulmonary resuscitation (DI-CPR) for bystanders. ⋯ Video-instructed DI-CPR significantly improved the chest compression rate compared to the audio-instructed method, and a trend for correctness of hand position was also observed. However, this method caused a delay in the commencement of bystander-initiated CPR in the simulation setting.

Review Meta Analysis
The use of end-tidal carbon dioxide (ETCO2) measurement to guide management of cardiac arrest: A systematic review.
To identify whether any level of end-tidal carbon dioxide (ETCO2) measured during cardiopulmonary resuscitation (CPR) correlates with return of spontaneous circulation (ROSC) or survival in adults experiencing cardiac arrest in any setting. ⋯ Based upon existing evidence, ETCO2 levels do seem to provide limited prognostic information for patients who have experienced cardiac arrest. Given the many potential confounders that can influence initial ETCO2 levels, extreme or trending values may be more useful than static mid-range levels. Additional well-designed studies are needed to define optimal timing for the measurement of ETCO2 for prognostic purposes.
