Long couple of days but better now

Hi everyone. After the second trial off Jackson seemed to go downhill. He would drop his oxygen saturation for no reason and it would take him a long time to recover. We also noticed that his abdominal cavity was beginning to swell. The did chest x-rays to make sure none of the tube had moved, and an ultrasound of his belly to see what was causing the swelling. The chest x-ray showed no change. The abdominal ultrasound (sonogram) showed fluid in his abdominal cavity. They are not sure whether the fluid is blood or infection. They have tested his blood for infection and it came back positive. They this does not necessarily mean Jackson has an infection but it is likely. They started him on two types of antibiotics a couple of days ago because he was dropping his oxygen saturation for no reason, just in case. The night of 3/17 he seemed to be doing worse. His abdomen was even more distended, and his oxygen saturation was very unstable. He would take a lot longer to recover after his saturation dropped. They even tried to manually bag him to get his oxygen back up, this worked a little but not great. They finally decided to change the setting on the ventilator, leaving more pressure in his lungs after each exhale. This finally started to work. His oxygen began coming back up. It took about an hour, but his oxygen went from 60% to about 80%. By 5am on the 18th his oxygen saturation was staying in the 90s. He was able to maintain his oxygen saturation all through the 18th, and so far today the 19th. He was even stable enough to change his linens. When they changed his bedding his oxygen did not drop at all. He is much pinker and looks like he feels better today. Everyone thinks that the antibiotics are starting to work and he is getting over his infection, which will make everything improve. They have been measuring his abdominal circumference and it has been fluctuating, they say that is not unexpected at this point. His abdomen looks much better though, it does not seem near as tight or shiny.
So in summation we had a very rough couple of days, and Jackson was very critical. Jackson now seems to be doing so much better, and appears more stable. All of his numbers; blood gases and oxygen saturation have all improved immensely, and have been stable for 2 days (18th and 19th). He looks much better the last couple of days. We took some pictures this afternoon, and I will post them this evening. I am so sorry for not posting for a couple of days, we were just busy. Thank you everyone for your thoughts and prayers they are greatly appreciated and I know they are helping, please keep them coming. Sorry this post is so long.
Love
Kimberly and Adam
