They attempted to lower his FiO2 to 65% this morning, but he didn't tolerate it well so they returned it to 75%. The doctor then ordered a change to his ventilator settings (IP 38, PEEP 20) which increased the pressure pushing into his lungs and also increased the resistance on exhalation (keeping his lungs open more) and he seemed to do a bit better. His tidal volume (volume of air in each breath) increased to 550 mL (up from < 450 mL) which helped oxygenation. Late this afternoon they reduced the FiO2 to 65% and he was able to tolerate it without problems. They reduced it again to 60% at about 6:00 PM and his SpO2 was still maintaining 93% at 10:00 PM tonight. This is the process of starting to wean Stan off the ventilator. They are also starting to slightly reduce the levels of the steroids, pain medication, and paralytic agent they have been giving him.
We are encouraged, but remain cautious due to the up and down nature of his condition. Go, Pop, Go!
