Elderly hemoglobin 195g / L first need to clarify the cause of the disease, such as physiological factors, true erythrocytosis, pulmonary heart disease, etc., in accordance with the doctor’s instructions to improve the use of general treatment, drug therapy and so on. 1. Physiological factors: for example, plateau residents, due to the low content of oxygen in the air, need to synthesize a large number of hemoglobin to compensate for oxygen supply, which is a normal state and does not require intervention. 2. True erythrocytosis: it is a clonal chronic myeloproliferative disease of hematopoietic stem cells, and there is often an increase in red blood cells during the proliferative phase. The blood volume can be reduced to normal in a relatively short time through intravenous bloodletting under the guidance of doctors, which will reduce the symptoms and decrease the chance of bleeding and thrombosis; chemotherapeutic drugs, such as tritiated alkaloids and hydroxyurea, etc. can also be applied to inhibit myeloproliferative process. 3. Pulmonary heart disease: due to pulmonary hypertension and other causes of heart failure, the blood oxygen level is reduced, and red blood cells need to be elevated to compensate. It is necessary to control the infection immediately, for example, cefepime; improve ventilation and so on to improve the hypoxia, and if necessary, it is necessary to apply cediran intravenous drip to improve myocardial blood supply. The increase in the amount of hemoglobin in the organism may also be due to other reasons, it is recommended to consult a doctor in time to identify the causes, standardize the treatment under the guidance of the doctor, and comply with the doctor’s instructions for the use of medication.
