I care for my 84 mom with emphysema and afib. Began supp.o2at night and with excursion in jan this year.
2L used at night but now with more breathlessness,some wheezing. This has progressed in last few days with no ability to move about with out o2 dropping 80s.
Heart rate drops low.
She was very active at least around house but now sleeps all time. A significant amount of change quickly. Is this lung or heart related. Looking for direction
Any thoughts.
