ABSTRACT:
The invention relates to a device intended for monitoring the carbon dioxide output, oxygen consumption and respiration quotient of a patient connected to a respirator. The device comprises O.sub.2 (15) and CO.sub.2 (14) analyzers, a mixing chamber (6), a constant flow fan (8), a gas collector hose (2) and magnetic valves (10-13). The carbon dioxide output and oxygen consumption are directly calculated from the carbon dioxide content of gas mixed with constant air flow from said mixing chamber, from the carbon dioxide and oxygen contents of the gas in said mixing chamber, and from the oxygen content of the gas delivered into a patient by said respirator.
