What is the target PETCO2 range after ROSC?

After ROSC, the goal is to maintain normal ventilation in a way that keeps CO2 at normal levels. PETCO2 serves as a noninvasive stand-in for PaCO2, guiding how you ventilate the patient. Keeping PETCO2 in the mid-normal range, about 35-45 mm Hg, helps ensure cerebral blood flow is adequate without pushing pressures too high. If CO2 drops too low, cerebral vessels constrict and blood flow to the brain can drop, risking ischemia. If CO2 climbs too high, cerebral vessels dilate and intracranial pressure can rise, worsening brain injury. So targeting normocapnia around 35-45 mm Hg balances cerebral perfusion and intracranial dynamics after ROSC.
