I just had some questions and I hoped maybe I could find some answers here. Our daughter was recently hospitalized for some type of respitory issues. One doctor said he thought she had pneumonia, one said no pneumonia, one said pertussis(whooping cough)that came back negitive, so they decided that she must have slight pnumonia, but they were not sure.I don't know much about this but I know that her o2 sats were in the mid 80's, and they were totally paniced, we have since got them to stay as high as 95 without any oxygen, which seems to be acceptable but not desirable. She was so sick though that they said said something more serious must be going on. For a questionable pneumonia she was very sick, they were going to tansfer her if they didn't start to see improvement soon. She was on a fast track down hill. She did get better finally. Now they are going to test her for cystic fibrosis with a sweat chloride test, they say to rule it out, I guess they say because of the combination of this recent hospitalization and also some digestive problems that she has been having. I guess I have just come here to find out what exactly cystic fibrosis is, please forgive me for my ignorance on the subject, they don't really cover this anywhere so untill now I have never really thought to research it. Also I think I have come hopeing to hear that this doesn't really sound like cystic fibrosis. Mostly I just want to hear opinions from real people, the doctors always seem like they are hiding something or just not giving us all of the information. Thanks for any help.
