Brian's overall condition improved yesterday. Alyssa and I drove home and slept in our own bed last night because, as the nurse said, Brian was in a better place than he was Wednesday night. His blood pressure is at an acceptable level, pulmonary hypertension is under control and his potassium level is right where it should be so his kidneys are functioning properly. The doctors also pay close attention to blood gas which is a number that seems to fluctuate often. His blood gas had dropped after his surgery but with a little adjustment to the ventilator it went right back up. We called this morning to find nothing really changed over night. We are on our way back to the hospital in a little while.
