Under normal circumstances, blood lactate is generally 0.4 to 1.8 mmol/L. Hyperlactatemia occurs when the blood lactate concentration is greater than 1.8 mmol/L. When the blood lactate value is greater than 4 mmol/L, it is a more serious situation.
Blood lactate is an indicator used in blood tests to show the state of microcirculation in the body and whether the organs are lacking in oxygen. When the blood lactate concentration is greater than 1.8mmol/L, it is clinically called hyperlactatemia, and most of the patients are caused by insufficient oxygen supply, malignant tumors and so on.
Elevated blood lactate can be alleviated by increasing oxygen intake, avoiding the use of drugs that can increase blood lactate, such as phenelzine, and controlling the underlying disease.
When the patient’s blood lactate is greater than 4mmol/L, it is a more serious, more critical situation, indicating that the body has a severe hypoxia, and the chance of death will also increase. It is possible that at this time the patient has already occurred shock, respiratory failure, heart failure and other pathological changes, the higher the level of lactic acid, suggesting that the body’s circulation is worse, the more critical condition.
When the patient’s blood lactate is greater than 4mmol/L, his vital signs should be closely monitored, and appropriate treatment should be carried out under the guidance of the doctor to avoid serious consequences.
