My father seemed to be doing much better during the first half of last week, until early Wednesday morning when he was found wandering the hall pushing his drip tree, unable to remember why he was in the hospital. After some new testing, it was found that his C02 levels were still high and that he was not exhaling hard enough while sleeping, thus starving his bloodstream of oxygen.
A new breathing machine was rustled up and prescribed for the following night, and the change was dramatic. The other bit of good news is that the chest tube will (hopefully) be coming out today and he can heal up completely. Now, the only problem will be braving the ice storms to get him home.
