OEM Capnography Products


Capnography is the measurement of carbon dioxide (CO2) in respiratory gas.  A capnograph displays a waveform of CO2 (measured in millimeters of mercury, kilopascals, millibars, or volume percent).  It may also display the value of CO2 at the end of exhalation (etCO2), the minimum value of CO2 during inspiration (fiCO2), and the respiration rate (RR).  Capnography is rapidly becoming a standard of care in anesthesia and respiratory therapy.  In 1986, the American Society of Anesthesiologists (ASA) formally encouraged the use of capnography in clinical anesthesia.



TreyMed offers OEM products to assist medical device manufacturers in a broad range of applications.


Capnography has been shown to be an effective monitoring tool for:

  • Intubation verification (trachea versus esophagus)

  • Monitoring adequacy of ventilation

  • Detecting disconnection of breathing system or ventilator

  • Monitoring conscious sedation

  • Detecting effective cardiopulmonary resuscitation

  • Monitoring ventilation of closed head trauma

  • Assessing seizure conditions

  • Evaluating bronchospasm and asthma

  • Monitoring malignant hyperthermia

  • Metabolic assessments

Our capnography products can be incorporated into various medical devices which address these clinical indications.
