Acute cardiac care & resuscitation

Higher ventilation rate is associated with increased return of spontaneous circulation in in-hospital cardiac arrest patients with advanced airways

Authors' conclusion

Ventilation rates above guideline recommendations were common. Rates between 12 and 26 breaths/min were associated with improved ROSC, potentially due to enhanced perfusion.

Study context

Participants
222 patients
