Bronchopneumonia in 80yr old woman

My mother is 82. She has advanced stage Alzheimer's and is wheelchair bound. She has been having a difficult time expectorating large gelatenous phlegm stuck in her throat for a few months.

Two weeks ago she had a low fever off and on 37.3-37.8C. She was on a childrens antibiotic and a cough syrup which did not work. She was then prescribed amoxicillin 400mg children's dose for 5 days 2x/day. Everytime she had a dose she would start to shake and shut her mouth trying to breathe which caused her to hyperventilate. It would take 4hrs for things to calm down. More of the thick clear ropy phlegm would get stuck and the only way to get it out is to reach into her throat and pull it out.

She worsened and last Sunday took her to a hospital where we were told that she had an infection of the lungs that had been going on for some time and symptoms of pneumonia.

She has been in bed for the past 7 days. When we tried to feed liquids she would gag and choke not able to swallow thru phlegm. She would only get about 20ml of liquid on her own.

She has been on an antibiotic for the past 5 days 3x/day. No more fever, secretions went from clear thick/gelatenous to foamy white to now yellow green which come out of her throat into her mouth. She has not taken anything orally for the past 4 days and is beeing given liquids thru an IV.

She is weak, if I sit her up for more than 15mins she starts to shake, goes pale and sweats. If I try to feed her she chokes and can't swallow. Her hemoglobin is low and her createnine is high. There is loud gurgling in her lungs.

Please help. I keep reading about all the pneumonia homeopathic remedies but don't want ot start using without a direction. I have had great success with Ferrum Phosphoricum, but I think we are past this stage with my mother.

Thank you.
