Mom says that Dad is fairly alert and talking today, although he's taken a number of naps. This afternoon the nurses have gotten him up from the bed to sit in a reclining chair for awhile, despite his protests. It is uncomfortable for him to move, but it is beneficial for both his lungs and his muscles.
Last night Dad had several episodes of irregular heartbeat, but today that seems to be under control. Mom did get home to sleep last night, but she wasn't able to get back as early as she wanted to this morning, so she may sleep on the couch in the ICU waiting room tonight.
Thank you all so much for caring and praying.
