n. pl. ac·i·do·ses (-sēz')
An abnormal increase in the acidity of body fluids, caused either by accumulation of acids or by depletion of bicarbonates.
abnormally high level of acidity, or low level of alkalinity, in the body fluids, including the blood. There are two primary types of acidosis: respiratory acidosis and metabolic acidosis. Respiratory acidosis results from inadequate excretion of carbon dioxide from the lungs. This may be caused by severe acute or chronic lung disease, such as pneumonia or emphysema, or by certain medications that suppress respiration in excessive doses, such as general anesthetic agents
