Were at Childrens hospital Los Angeles. They have a large CF center there. Shes on Pulmozyme. No Hypertonic Saline. They said they dont prescribe it until 6yrs of age due to possible irritation. Her right middle lobe has always been her problem spot. Shows up on every xray and only clears up about 50% after IV antiboics. Clinicaly she is excellent. Growing well, lots of energy, no cough, FEV 102. We meet with the dr. this wednesday to see what he suggests. Thanks 4 your replies!
