Introduction
          The model  CMZ30 is a stable and reliable end-tidal CO2 module with high integrity, developed by CapnoMed Medical Co.Ltd., adopting the non-dispersive infrared technology with two wavebands, the latest microprocessor and digital signal processing technique, and proven concentration algorithm. The module can accurately measure the concentration of the end-tidal CO2, the concentration of the inhaled CO2, respiratory rate, etc. with the CO2 curve diagram in a fast and exact manner. The model CMZ30 is perfectly applicable to person at different age group, such as baby, child and adult. The sampling flow rate is setup on the upper computer, and the minimum rate can be lowered to 50ml/min. The standard RS232 communication interface can help to quickly integrate the model CMZ30 with the monitor or other medical systems which need CO2.
