My father he had his fist aspiration pneumonia. We had to do the PEG, since he failed the swallowing test. Now he is in the rehab center. But he has a lot of secretion. How do we clear it? He can't cough it out. Can anyone help? His breathing is very hard. That's I think due to the phlegm. How can we help him? He's been given naubulizer to help him, but I think he got some allergic reaction. Can anybody give some advice please? I am new to the forum. But he posts I am reading are so helpful. How often are the aspiration pneumonia coming back?
