Low carbon dioxide binding capacity cannot be treated by eating, it needs to be treated by e.g. sodium bicarbonate IV depending on the cause. Carbon dioxide binding capacity represents the level of bicarbonate in plasma, i.e., base reserve, and the normal value is 22-28 mmol/L. The patient’s carbon dioxide binding capacity is low, suggesting that the body has insufficient metabolic acidity. Low carbon dioxide binding capacity suggests that the body’s alkali reserve is insufficient, and it is considered that the patient has metabolic acidosis or respiratory alkalosis, which needs to be further perfected with other related examinations to clarify the cause of the disease and carry out etiologic treatment. At the same time, it is also necessary to correct acid symptomatic treatment, can be given 5% sodium bicarbonate intravenous drip, to maintain the body’s acid-base balance. The examination found that the carbon dioxide binding capacity is low, the doctor needs to formulate individualized diagnosis and treatment plan according to the patient’s specific condition. By eating what is ineffective to correct the acid-base balance, should actively cooperate with the doctor’s treatment, do not blindly believe in dietary therapy, prescriptions and other delays in the condition.
