The majority of patients with ROSC from OHCA require intubation and mechanical ventilation.
Correctly managing the ventilator in the post-arrest patient is critical for improving outcomes.
As patients are at high risk for ARDS, use lung-protective ventilation with tidal volumes between 6 to 8 ml/kg of ideal body weight and PEEP of 5 to 8 cm H2O.
There is a U-shaped relationship between neurologic outcomes and both PaO2 and PaCO2.
Target normoxia (SpO2 94% to 96%) and avoid hyperoxia and hypoxia.
Target normocapnia (PaCO2 40 to 50 mm Hg) and avoid hypercapnia and hypocapnia.
Use an analgosedation approach with short-acting analgesics and sedatives, such as fentanyl and propofol.
