I cant believe i forgot to mention this. While i was in the Hospital, i requested a new nebulizer every treatment. At first the RT's said it wont go over well because everyone uses the same one for 24 hours no matter how many treatments in that 24 hour period. Then they explained how they tap them clean rather than use tap water because of the bacteria tap water can harbor. Then one of the Pulmonologists came in and asked me why i felt the need for a new nebulizer each time since all the patients in the hospital that require nebulized reatments always use the same nebulizer for a 24 hour period before throwing them away. I reminded her that she is talking about generally healthy people with generally healthy lungs that can fight off almost all germs and bacteria, but those of us with cf simply cant.I told her that even with all the tapping they are doing to get the medicine out, there will always still be some inside the chamber and if you let that just sit for a few hours it will do nothing but collect germs and bacteria and the last thing we need is new germs and bacteria introduced back into our already compromised lungs. At home we sterilize them, but in the hospital there is no way to do that. She said they never thought of it that way ( i guess not....they have healthy lungs and wouldnt need to think that way) and said ok she will tell the RT's to give me news ones each time. Well a week later 2 days before i was discharged the one RT and a nurse told me there was a staff meeting the night before, and decided that based on what i said...... from now on, the cf patients will get new nebulizers with each treatment . YAY !! I am THRILLED that my big mouth actually made a difference in this world for the better....lol
