Definition of Acapnia


Acapnia: Less than the normal level of
carbon dioxide in the blood. The opposite of hypercapnia. The origin
of the word "acapnia" is curious. It comes from the Greek "a-"
meaning "without" + "kapnos" meaning "smoke" so acapnia literally
means "smokeless" referring to carbon dioxide which is a principal
part of smoke.
