It irritates me when they think they know the patient better than the family. You need a sit down with the dr. Make your requests (up as much as possible - more nutrition) my father was not a cancer patient but a stroke patient. They had him in bed 20 hours a day, he ended up with pneumonia as well. This along with general negligence killed him. You need to restate his history of getting pneumonia when hospitalized for extended periods. Micro aspiration could relate to small amounts going down when he's taking in food. I argued my brains out to have his diet changed they fought me at every turn- they kept saying he was aspirating - he was in bed for extended periods that was a major contributing factor. Good luck and push
