What does it mean if blood test results show high carbon dioxide levels, and what should be done?

In general, a high blood carbon dioxide level detected through laboratory testing may be caused by respiratory acidosis, metabolic alkalosis, glomerulonephritis, or other conditions, and treatment should be tailored according to the specific diagnosis. Details are as follows:

1. Respiratory Acidosis

Respiratory acidosis is a condition in which reduced breathing or impaired lung function leads to a decrease in the body's pH level, resulting in elevated carbon dioxide levels. Patients should be given low-flow oxygen therapy, and mechanical ventilation may be necessary in severe cases.

2. Metabolic Alkalosis

Metabolic alkalosis occurs when excessive alkaline substances are ingested or when the body produces too much base, which can also lead to elevated carbon dioxide levels. It is recommended that patients stop or reduce intake of alkaline substances, which usually allows symptoms to gradually improve.

3. Glomerulonephritis

Glomerulonephritis damages the kidneys, which play a key role in regulating the body's carbon dioxide levels; therefore, this condition may lead to increased carbon dioxide levels. Patients are advised to take medications such as levofloxacin tablets or moxifloxacin hydrochloride tablets as prescribed by their doctor.

Besides the above, other possible causes include pyelonephritis, acute asthma exacerbation, and acute respiratory distress syndrome. Patients should seek timely medical attention if they experience any discomfort to avoid delays in treatment. Additionally, maintaining a light diet and getting adequate rest are recommended in daily life.
