PulmCrit Wee- Oxygen-ICU trial: 100% isn’t an A+

Among intubated patients, we can often control the pO2, pCO2, and pH. Sounds great. Unfortunately, we also have no idea which numbers we should be targeting. Should we target a normal pH, or permissive hypercapnia? Should we shoot for a normoxia, try to maximize the oxygen delivery (hyperoxia), or allow for permissive hypoxemia? Nobody knows. We check ABGs and tweak the ventilator, but it's often dubious whether this helps our patients.
