Hemoglobin is the fluid that transports blood cells. If you get a transfusion of red blood cells, they would be in the hemoglobin even if it is low.
blood transfusion and low iron
If you have a low blood pressure, low hematocrit and hemoglobin, you need to have a blood transfusion.
I recently had an ulcer in the duodenal wall, the hemoglobin dropped to 3.8 before a transfusion began. I had loss 5 pints and unresponsive due to lack of blood to the brain. They added 7 units. I was unconscious for about 30 hours and on a ventilator until my body could function again. Another 2 units were added later to bring the count up to 9.
normal hemoglobin level is between 12-18 g/dL. elderly patient's may be slightly less.
If your hemoglobin level is low, you need to do something about it. The question is how low? If it is below 8, you may need a blood transfusion. If it is above that, you need to start eating red meat, green vegetables, and taking an iron supplement.
This isn't really a question, but yes, a hemoglobin level of 7.5 is considered anemic. If you are feeling symptomatic (short of breath, fatigued/tired, dizzy, etc.) you should probably go to the emergency department. If your hemoglobin drops below 7 or you're having symptoms, it's recommended that you get a blood transfusion to prevent your hemoglobin from dropping too low. Your hemoglobin is important because it is responsible for your red blood cells' ability to provide all of the tissues in your body with oxygen.
Anemia is a deficiency in the amount of hemoglobin in the blood.
An abnormally low quantity of hemoglobin in the blood is called anemia. Anemia also refers to a low red blood cell count.

Low BPG levels indicate a low hemoglobin level in the red blood cells.
Iron
Eat bannannas for potasium and eat red meat for red cells or get a blood transfusion.
