Abstract

See full text

The capnometer of the invention is an equipment which detects a signal which time-varies in accordance with a carbon dioxide concentration from a respiration gas, thereby calculating the carbon dioxide concentration. The capnometer has: carbon dioxide concentration calculating device for detecting the maximum value for each expiration from a concentration signal corresponding to the calculated carbon dioxide concentration, for comparing the maximum value with concentration signals respectively corresponding to a plurality of predetermined concentration ranges, and for outputting one of different control signals for the concentration ranges; and reporting device for outputting a sound corresponding to the carbon dioxide concentration, in accordance with the control signal.
