Performance of dispatcher-assisted cardiopulmonary resuscitation integrating with mouth-and-nose covering instructions during the COVID-19 pandemic: a population-based retrospective study

This study demonstrated that the modified DACPR protocol incorporating infection prevention measures was associated with a statistically significant delay of approximately 15.0 s in CPR initiation. However, given the low adherence rate, the overall impact of these measures on DACPR performance was limited. These findings highlight the need to increase adherence to infection prevention measures while minimizing delays in life-saving interventions, particularly during pandemics caused by airborne pathogens.
