Red blood cell hemoglobin hematocrit is high

The relationship between red blood cells and hemoglobin is very close. Hemoglobin is needed to complete the function of red blood cells. A high hemoglobin hematocrit generally means a high red blood cell count, which has a certain impact on the human body. Shock in the body can also lead to a high red blood cell count.

1. High hematocrit

Cardiogenic shock Cardiogenic shock in a narrow sense refers to the severe stage of pump failure that occurs in acute myocardial infarction (see acute myocardial infarction). In acute myocardial infarction, if the clinical symptoms are accompanied by low blood pressure, insufficient skin perfusion, decreased renal blood flow, central nervous system dysfunction and other manifestations of microcirculatory failure of important organs, and if hypotension caused by drugs (such as analgesics, vasodilators, diuretics), poor food intake, fluid loss or insufficient fluid replacement causing decreased blood volume can be ruled out, the diagnosis of cardiogenic shock can be considered.

2. Hemoglobin

The relative increase is due to the large loss of water, such as continuous vomiting, repeated diarrhea, sweating, polyuria, large-area burns, etc., which leads to a decrease in plasma volume and blood concentration, resulting in a relative increase in the concentration of red blood cells and hemoglobin. This is a temporary increase and will return to normal with proper hydration.

2) Absolute increase is usually due to pathological factors that cause long-term hypoxia of the body, stimulating the secretion of erythropoietin, thereby causing compensatory proliferation of red blood cells and the occurrence of secondary erythrocytosis. It is seen in severe chronic cardiopulmonary diseases, chronic carbon monoxide poisoning and mountain sickness. When suffering from primary erythrocytosis, the red blood cell count also increases significantly, up to (7~10)*10^12|L.

3. Others

The number of red blood cells is affected by many physiological factors, but compared with the reference value of the same age and gender, it is generally within ±20%, mainly seen in hypoxia such as newborns (increased by 35%), mountain dwellers (increased by 14%), mountaineers, strenuous exercise and physical labor; increased androgen in adult males than in females; increased adrenal cortex hormones such as mood swings; long-term heavy smoking; venous compression time > 2min (increased by 10%); capillary blood is higher than venous blood measurement results (increased by 10%~15%); intraday differences (highest at 7 am); use of epinephrine, glucocorticoid drugs, etc. Pathological changes of polycythemia can be seen in relative increase, such as temporary blood concentration, vomiting, high fever, diarrhea, polyuria, sweating, large area burns, etc.
