My wife is a CF patient and had a bilateral pulmonary transplant 10 years ago. Recently (about 7 weeks ago) she contracted the first serious infection since the transplant procedure. She was hospitalize 10 days ago (after consistent drop of her physical ability) had a bronchoscopy done and the histologic examination determined she has Gram-negative bacteria (most probably pseudomonas). She was discharged 5 days ago with a PICC line for IV piperacillin treatment. Her peak flow went from her normal 380mL to 200-240 mL and has not improved even after she started to receive the piperacillin (it actually dropped a bit yesterday to 180-200). Besides her 4 times a day albuterol dosage she inhales distilled water in between to loosen up her sputa (I hope that's the main reason for her poor peak flow performance). She is supposed to have a check up tomorrow but because of insurance complications the hospital administration says that they won't see her until the problem is resolved (which might take up to a week). Is it normal to take so long for patients like my wife before any lung volume improvement can be seen? How long does it usually take before the lung volume starts to increase again? I hope I am stressing out for no reason and that the doctors only refuse to see her right away because they know she's out of lethal danger. But since this is America, a country with one of the most terrible medical systems I am not so sure about that and I want to make sure that her symptoms are completely normal and there's nothing to be worried about. thank you so much for any input Urban
