Mainstream EtCO2 Module is a non-dispersive infrared analyzer. In Module, infrared light is generated by the Module and beamed through the sample cell to a detector on the opposite side. CO2 from the patient that is aspirated into the sample cell absorbs some of this infrared energy. The Module determines CO2 concentration in the breathing gases by measuring the amount of light absorbed by these gases. The Module contains a reference channel, used to compensate for optical changes, so that the system is in a state of calibration. EtCO2 is displayed as a numerical value in millimeters of mercury (mmHg), percent (%), or kilopascals (kPa). In addition, a CO2 waveform (capnograph) may be displayed which is a valuable clinical tool that can be used to assess patient airway integrity and proper endotracheal tube (ETT) placement.
Respiration rate is calculated by measuring the time interval between detected breaths.

Portable and Modular design

Elegant in appearance, clear in labeling and easy to operate.
