CO2 appears in blood as Bicarbonate HCO3). It is an alkali (basic) molecule contributing to the acid base balance of the body. HCO3 keeps the blood from becoming acidic. Acidity is defined as the negative logarithm (pH) of the hydrogene ion concentration of any fluid. pH 7 is the value which is neutral (Neither acidic nor basic). The normal pH range of the human body is between very narrow limits (7.35-7.45). This range is protected by the acid base buffer systems of the body. HCO3 is the indicator of the basic component of this system. It is also related to electrolyte panel (metabolic panel) of the body. Lungs and kidneys are the major organs involved in regulating blood pH.
Interpretation: Both high and low values of this sensitive component means that the body has turned into basic or acidic value which is fatal if not regulated. The imbalance is typically caused by some underlying condution of the disease.
