Hemoglobin, also known as hemoglobin, needs to be transfused when it is lower than 60g/L or when there are obvious symptoms such as dizziness, panic, low blood pressure, or shock.
1. Blood transfusion is needed when hemoglobin is less than 60g/L. In addition, blood transfusion is needed in acute anemia even if hemoglobin is not less than 60g/L and the patient has obvious symptoms such as dizziness, panic attacks, low blood pressure, and shock.
2. If the anemia is severe for a long time, it may lead to anemic heart disease, dizziness, headache, fainting after standing up, etc., and need active blood transfusion treatment.
3. When low hemoglobin is found, it is necessary to go to the hospital to find out the cause of anemia and further treat the cause of the anemia, and blood transfusion is only a supportive treatment.
When low hemoglobin is found, go to the hospital for further consultation and early treatment, and do not make any decision on your own to avoid delaying the condition.
