I have a question about PEG tubes. My PALS was diagnosed 18 months ago and has been on a BiPAP 24/7 for over 1 year. I don't know what his FVC (I think that's the correct term) is but I expect it is not good. Is he still eligible to get a feeding tube? His speech and ability to swallow had declined dramatically over the past 4 weeks but I'm afraid we may have missed our opportunity for a PEG tube. Do you need to go under general anesthesia? He couldn't handle that I'm sure. Any information would be greatly appreciated.
