Abstract
The invention resides in a respiratory sonification monitoring method and system for monitoring respiration in a subject including the use of capnometric means for measuring carbon dioxide concentrations, flowmeter means for measuring gas flow and volume of gas; means adapted to process into digital information, signal output from the capnometric means and the flowmeter means, sound synthesizer means adapted to convert the digital information into synthesised audio output, wherein, changes in respiratory flow during inhalation and exhalation, and changes in end tidal carbon dioxide concentrations (ETC02) and cumulative tidal volume (cumVt) of the subject can be represented as changes in synthesised sound heard through a loudspeaker, headphone or ear piece.
