My mother has end-stage emphysema, takes no oxygen, smoke, have confusion and dizziness. Does she have little? Is 84 years old and have extreme fatigue after climbing just a couple of steps. He has lost a lot of weight now weighs about 88 pounds and has no appetite.

It is often difficult to estimate the life expectancy of a patient even when the family medical history , physical conditions, laboratory tests, etc. are known. People suffering hypoxia due to be in the final stages of lung disease are at risk of falling (and thus breaking a hip , have subdural hematomas , etc. . ) , Strokes, heart attacks and , of course , unemployment breathing . Any of these conditions could result in death , on the other hand, his mother may still have many months ahead. His mother 's refusal to quit and confusion ( which no doubt is compounded by low levels of oxygen in the blood) are very worrying. It is not uncommon for these individuals set fire to their environment by forgetting to turn off a cigarette or falling asleep while smoking . I suggest you talk to your mother 's doctor about your prognosis. Meanwhile, it is important that your use of flammable materials is closely monitored . Best wishes to you and your mother.
