Elevated bicarbonate is mainly seen in metabolic alkalosis. It is recommended to improve the body’s electrolyte balance, respiratory pattern, and the body’s acidity and alkalinity under the guidance of a physician. When patients have high bicarbonate, they should be actively examined to clarify the original disease and treat the symptoms. 1. Balance electrolytes:When patients have electrolyte disorders, they need to actively replenish electrolytes, such as saline infusion or potassium supplementation, and bicarbonate will decrease when electrolytes return to normal. 2. Change the respiratory pattern:It is necessary to treat for the original disease, such as chronic obstructive pulmonary disease, respiratory failure, etc., and if necessary, a ventilator can be used. Bicarbonate will gradually decrease as the condition improves. 3. Correct the acid-base level: arginine can be infused to regulate the acid-base level of the body. Patients should consult the doctor in time to clarify the diagnosis and follow the doctor’s instructions for treatment.
