This compares PaCO2-sedation≤60 mm Hg and >60 mm Hg (201 total patients); PaCO2-%increase from baseline of ≤50% and >50% (194 total patients); and pH≤7.2 and >7.2 (201 total patients).
ICU, intensive care unit; LOS, length of stay; PaCO2, arterial partial pressure of carbon dioxide; ValveDepl, valve deployment.
