This paper presents the results of the calibration process of a capnometer fully developed in Cuba.The device measures the partial pressure of CO2 in the exhaled air by the patient being treated,processes the acquired data and calculates the concentration of CO2 as a time function during the breathing process as well as the End-tidal CO2 value,extremely useful for the anesthesiologist to assess the patient status.The calibration method is described and the corresponding results are presented and discussed,complying with the safety requirements established in the IEC 60601-1:1988 and the ISO 21647:2004 medical equipment safety standards.Results are presented that support the criterion of evaluating the design as a good piece of work,since the accuracy of measurements agrees with the values specified in the ISO 21647 particular standard.
