The description details a standard non-dispersive infrared gas analyzer and its operation based on physical principles of light absorption. There is no mention of AI or ML algorithms for data processing, interpretation, or decision-making. The calculations are based on direct measurements and calibration against known values.
No
The device is a monitoring system that measures carbon dioxide in breathing gases and displays CO2 concentration and respiration rate. It does not provide any therapeutic intervention.
Yes
This device monitors carbon dioxide levels in breathing gases and displays a CO2 waveform (capnogram), which is used by medical professionals to assess patient airway integrity and endotracheal tube placement. These measurements provide information that aids in diagnosing or assessing patient conditions related to respiratory function.
No
The device description clearly outlines hardware components like an infrared gas analyzer, infrared sensor, and pressure sensors, indicating it is not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The CO2 Mainstream Module analyzes the concentration of carbon dioxide in the breathing gases of a patient. This is a measurement of a physiological process (respiration) occurring in vivo (within the living body), not a test performed on a sample in vitro (outside the living body).
- Intended Use: The intended use clearly states monitoring during anesthesia/recovery, Emergency Medicine/Transport, or Respiratory care, all of which involve monitoring the patient directly.
- Device Description: The description details the analysis of gases in the breathing pathway, not analysis of bodily fluids or tissues.
Therefore, the CO2 Mainstream Module is a physiological monitoring device, not an in vitro diagnostic device.

Intended Use / Indications for Use

Device Description
The CO2 Mainstream module is a non-dispersive infrared gas analyzer with an auto-zero adjustment systemand 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 theenergy 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's memory.
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.
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.
