# Purpose of Submission
This is a new traditional 510(K) submission of a Carbon Dioxide Gas Analyzer.
# Device Description
The CO2 Mainstream module is a non-dispersive infrared gas analyzer with an autozero adjustment system and gain control.
The operation of the CO2 Mainstream module is based on CO2 energy absorption rates. CO2 molecules absorb infrared light energy of specific wavelengths, with the amount of energy absorbed being directly related to the CO2 concentration. When an IR light beam is passed through a gas sample containing CO2, the electronic signal from the infrared sensor (which measures the remaining light energy), can be obtained. This signal is then compared to the energy of the IR source, and calibrated to reflect CO2 concentration in the sample accurately. Calibration is performed using the infrared sensor's response to a known concentration of CO2 stored in the module'smemory.
The circuit module retains the atmospheric absolute pressure sensors and control of the pressure sensor. Modules can measure atmospheric pressure, and atmospheric can compensate the calculation for the concentrations of carbon dioxide, which improves the design accuracy.
{5}------------------------------------------------
The module then determines CO2 concentration in the breathing gases by measuring the amount of light absorbed by these gases. EtCO2 displays a numerical value in millimeters of mercury (mmHg), percent (%), or kilopascals (kPa). In addition, a CO2 waveform (Capnogram) may be displayed, which is a valuable clinical tool that can be used to assess patient airway integrity and proper endotracheal tube placement. Respiration rate is calculated by measuring the time interval between detected breaths.
The differences between the Capno M and M+ are only with the intended patient type. The Capno M is intended for use on intubated patients, where the Capno M+ is intended for use with intubated and non-intubated patients. The operating principles, unit of measurement, ETCO2 measurement range, accuracy, respiration rate range, and respiration rate accuracy are the same for both devices.
# Indication for use
The CO2 Mainstream Module is intended to provide carbon dioxide monitoring to a monitoring system during anesthesia/recovery in host Emergencv Medicine/Transport or Respiratory care.
# Comparison with the predicate device:
Beijing Kingst Commercial & Trade Co., Ltd. believes that the Beijing Kingst Commercial & Trade Co., Ltd. CO2 Mainstream Module is substantially equivalent to the Respironics Novametrix. Inc. CAPNOSTAT 5 Carbon Dioxide Gas Analyzer (K042601).
There are differences in the CO2 response time and the respiration rate measurement range. The response time difference is 10 ms. This does not affect the accuracy or usage. The measurement range difference is at the lowest part of the scale. The predicate devices' range is 2-150 breaths per minute, where the submitted device range is 3-150 breaths per minute. The difference at the lower end of the range does not pose any risks or hazards to patients. They have the same intended use. The minor differences in technological characteristics do not raise issues of safety and effectiveness. The subject device is identical to the predicate device. Please refer to the following pages for specific difference details.
