More curve balls

Well, we had hoped that Keith was going to be off sedation today, and the breathing machine. We got to the hospital this morning, and the doctors had thought it would be best to wait another 24hrs before taking him off equipment, and off sedation.  Keith has a partially collapsed right lung, this can be common on a vent, and with laying because fluid (mucus plugs) can settle, and the patient isn't coughing them out.  They were repositioning Keith's body today, and doing a lot of Chest PT to help "clear" it out--- and so it doesn't get larger or turn into pneumonia. Specifically, the infection growing in his lungs, causing the collapse is MRSA.  He is now on an additional antibiotic to help the infection.
The doctors say that if the collapse/infection does not get any bigger, or keith doesn't require anymore additional oxygen, or ventilator changes OR does not desat tonight, they may still go ahead and pull the breathing tube out tomorrow.  If, any of these things change, he would need to stay on it longer.
We are disappointed that he couldn't be up today, but we understand why. Hopefully, IF he does get to get off things tomorrow, it will help him because then he can cough up whatever is in the lungs by himself, which will get the infection out.
They had weened him off a bit of sedation today (in preparation of extubating him) but, by this evening we had to have them increase it.  In the morning, he was answering yes or no questions by nodding and shaking his head. It was neat to communicate with him!  We asked him if he was cold, hurting, hungry-- things like that.  By night time tho, he was beyond frustrated, began thrashing his body, crying, and just not comfortable.  At that point, it was getting dangerous, in fear that he would self extubate!  We asked the nurses/doctors to increase sedation, and they agreed, it just wasn't safe for him to be that way. They will begin to ween him again tomorrow, in preparation again for extubation. 
Things are definitely day-by-day here. We pray and hope things are in better standing tomorrow, but you just never know what will happen.
Keith is VERY strong.  I know he will be okay. It's just very stressful to have 2 kids, and have our family divided.  I'm working on child care the rest of the week, as my husband needs to go back to work, and my babysitter back to school.  I believe I have a plan lined up, but I don't want to be to dead-set on something, because there are always curve balls in life!
Thanks to everyone that is praying for us. We appreciate it, more than I could ever describe.
