Theory of Operation The module is designed to work specifically with the DASH 3000/4000 monitor. It is an infra red CO2 analyzer utilizing on the mainstream Capnostat technology. It contains a sampling pump for pulling a gas sample into the analyzer. It mounts to the side of the DASH and connects to the existing CO2 connector. The supporting electronics and software in the DASH common to both the main stream sensor and the DASH CapnoFlex LF module. The sampling flow rate is fixed and internally regulated to 50 ± ml/min. A differential sensor pressure in the sampling circuit provides the signal for regulation. An occlusion can be detected by way of another pressure sensor constantly monitoring the pressure the sampling system for increased pressure. If the preset pressure is exceeded for 15 seconds the pump is turned off. The inlet to the analyzer is mechanically unique and only accepts an approved sampling line containing the water protection trap. The sampling cell and water trap is integral to the disposable sampling assembly. A reflective optical sensor provides a signal for enabling the pump. The analyzer has all calibration factors stored in an EEPROM. This allows for the use of the analyzer with any DASH as the calibration factors are read into the DASH each time a module is connected. Below is a block diagram of the module.

Verify Accuracy 1.
Return to MORE MENUS and select CO2 to open the menu.
2.
Select UNITS: and set to MMHg.
3.
Select CAL SENSOR TO ZERO CELL, then select READY. The on-screen message reads CALIBRATING.

Turn on the tank regulator for several seconds, then turn it off. If the NO BREATH DETECTED message appears, simulate breathing by turning the regulator on for several seconds, then off for several seconds.
6.
Read the EXP number. _________ EXP mmHg = CO2 value on tank X Barometric Pressure as noted above. Tolerance = ± 8%
If the module tolerance is outside the above range, return the module for repair.
