The respiratory gas monitoring device 100 includes a pump 110 connected to draw a flow of respiratory air, pressure sensors 150, 160 connected to measure an air pressure signal in response to the flow of respiratory air, and a pressure transducer 180c. .. Electrical circuits 170, 180 are operably connected to measure the flow through the pressure sensor. Gas component sensors 190, 192, 194 are arranged to monitor the target gas in the flow of breathing air. |
