What is hco3 in abg

HCO3 = calculated concentration of bicarbonate in arterial blood. Base excess/deficit = calculated relative excess or deficit of base in arterial blood. SaO2 = calculated arterial oxygen saturation unless a co-oximetry is obtained, in which case it is measured.

What does high ABG HCO3 mean?

A bicarbonate level that is higher or lower than normal may mean that the body is having trouble maintaining its acid-base balance, either by failing to remove carbon dioxide through the lungs or the kidneys or perhaps because of an electrolyte imbalance, particularly a deficiency of potassium.

What do HCO3 levels indicate?

This test measures the amount of bicarbonate, a form of carbon dioxide, in your blood. Bicarbonate is also known as HCO3. It's a byproduct of your body's metabolism. Your blood brings bicarbonate to your lungs, and then it is exhaled as carbon dioxide.

What does high pH and HCO3 mean?

An ele- vation of HCO3 (over 26 mEq/L), along with elevated pH, indicates metabolic alkalosis.

What makes HCO3 high?

Metabolic alkalosis is primary increase in bicarbonate (HCO₃⁻) with or without compensatory increase in carbon dioxide partial pressure (Pco₂); pH may be high or nearly normal. Common causes include prolonged vomiting, hypovolemia, diuretic use, and hypokalemia.
