Well, Dad had to go back to the hospital last night. He went to bed and seemed to be feeling good, but his breathing got bad again. Not as bad as the night before so Mom was able to drive him to Emergency. A male nurse saw her come in with Dad and said she looked familiar, she explained why and he whisked Dad away. His oxygen level was at 81, which is not good and he (the nurse) said when it's below 90 i think, they can make more decisions and he took him and admitted him right away to ICU. He is still in ICU, I just spoke to his nurse, she said he is doing okay.
