You are caring for a patient with an IBW of 50kg on the following settings, SIMV/VC, tidal volume 475ml, RR 15bpm, PEEP 5cmH2O, FIO2 0.50. You obtain a blood gas with the following results: ph 7.29, PaCO2 56, PaO2 70, HCO3 26. The physician asks you to make one single change, if needed. What would you do?

Thirty minutes after intubation and initiation of mechanical ventilation, a patient’s PaO2 = 55 mm Hg and the FIO2 = 0.5. To what should the FIO2 be set to obtain to best get a PaO2 of 80 mm Hg?
