My 87 year old Mother who has always been in good health started getting short of breath about 4 years ago just in the morning but she would exercise and walk and it would become normal. She had some other minor issues which were treated. However, three months ago the shortness became worse and worse. After three trips to ER and a 4-day stay in hospital she is home on oxygen not capable of doing anything basically. I give her breathing treatments and inhalers. She went from being totally outgoing and active to a totally inward focused person, can barely eat, cannot take any noise whatsoever, trouble with digestive system, etc. Been to several doctors including pulmonary. She is down to 94 lbs - I think she has given up. Is this the end - what am I looking at? I work full time and am her primary caregiver so I want to make plans for whatever she will need.
