(Hgb) is the major substance in red blood cells, and its level indicates the blood's ability to carry oxygen
throughout the body. Studies have shown that low hemoglobin, which may result in anemia
, is more common among patients with heart failure
than it is among people in the general population. As many as 25 percent to 60 percent of heart failure patients have anemia, defined as hemoglobin less than 12 grams/deciliter in women and 13g/dL in men. Studies have shown that if you have anemia and heart failure, your risk of death and complications are increased appreciably with as much as 30 percent to 60 percent additional risk of death and hospitalization from heart failure.
When hemoglobin is below 8 g/dl, death is not far from occurring thus a transfusion is required.
I suggest your father takes 2 unit of packed red blood cell transfusion immediately as his heamoglobin is already 8.2 g/dl so it is maintained above 8 g/dl.
1 unit PRBC transfusion increases haemoglobin
level by 1 g/dl.
Regards and take care
