Pop had another relatively tough night last night. He started having trouble oxygenating at around 10:00 PM last night, so the FiO2 on his ventilator had to be increased to 100%. Now his SpO2, or blood oxygen saturation, is in the high 90s percent-wise and his blood gas numbers have improved, but patients can't tolerate staying on 100% FiO2 for very long. The doctors feel some of his oxygenation problems are related his position on the bed. He is on a bed that automatically turns him on a regular basis and he does better in some positions than others. The doctors haven't started rounds yet, but should have a new action plan for the day later this morning. Hang in there Pop.
