Influence of different ventilation strategies during cardiopulmonary resuscitation on the return of spontaneous circulation in out-of-hospital cardiac arrest: a retrospective study from the German resuscitation registry

Respirator controlled ventilation with IPPV modestly but significantly exceeded expected ROSC rates in patients with non-traumatic OHCA. CCSV, the mode designed specifically for ventilation during CPR, does not seem to be superior to manual bag-valve ventilation. Randomized controlled trials are needed to refine mechanical ventilation strategies in CPR.
