Ventilatory parameters during emergency department–based CPR and exploratory associations with return of spontaneous circulation

Ventilation practices during ED-based CPR showed substantial variability and frequently deviated from guideline-recommended targets. While exploratory analyses suggested a potential association between moderate minute ventilation and ROSC, these findings are descriptive and hypothesis-generating. Further studies with predefined ventilation targets and time-dependent analyses are required to clarify optimal ventilation strategies during CPR.
