Mom took a small step in the right direction today. Still a long way from getting out of ICU, but her O2 saturation was 96-98 today without a rebreather unit. She only had one dip into the 80's today. If she holds strong through the night tonight, then they're going to try and back off the oxygen a little and see if she can keep the saturation levels up. Every day that goes by, they'll reduce the oxygen flow a little more until she gets to acceptable levels. Currently, she's at max flow, around 15-16 liters. She'll need to get all the way down to 2-3 liter pressure before they let her out of ICU.
But, she was in good spirits today and coherent for most of the day as well, which was good.
