The device working theory is NON-DISPERSIVE INFRA GAS ANALYZER. The device has an AUTO ZERO ADJUSTMENT SYSTEM and GAIN CONTROL The principle is based on the fact that 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 a 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 accurately reflect CO2 concentration in the sample. To calibrated, the infrared sensor’s response to a known concentration of CO2 is stored in the monitor’s memory.
End tidal carbon dioxide (ETCO2) monitoring is a non-invasive, convenient, real-time and continuous functional monitoring indicator. With the miniaturization of monitoring equipment, the diversification of sampling methods, and the accuracy of monitoring results, ETCO2 has been used more and more widely in the clinical work of the emergency department.
PETCO2 (End-tidal carbon dioxide partial pressure) reflects the complex physiological process of carbon dioxide generated by metabolism discharged from the lungs. It is considered as a non-invasive indicator of Alveolar ventilation, which can reflect the status of the body's ventilation and respiration; It can also reflect the changes of metabolic function and circulatory function.

EtCO2 has been recognized as the sixth basic vital sign besides blood pressure, SPO2, heart rate, respiration and body temperature. Under normal physiological conditions, PETCO2 has a good correlation with arterial partial pressure of carbon dioxide (PaCO2). Compared with EtCO2, PaCO2 has the disadvantages such as requiring arterial puncture, interrupting measurement and high cost. PETCO2 monitoring is non-invasive, continuous, simple and real-time. EtCO2 can timely and effectively guide doctors to quickly find and deal with abnormal conditions, and help judge the patient's condition and prognosis.
In addition, ETCO2 also has advantages in emergency prognosis, specifically, it can reflect the abnormal situation of human body in respiration, circulation and metabolism to a certain extent, and the portable instrument is small in size, convenient in measurement, able to quickly obtain measurement results without causing any damage to patients. Portable etco2 monitoring devices by Kingst can help you deal with these situations. Under the condition of normal ventilation and blood flow ratio, it can accurately reflect the partial pressure of bleeding carbon dioxide, which has the potential to replace the blood gas analysis, providing a possibility to quickly predict the prognosis of patients with spontaneous respiration.
Applying PETCO2 monitoring to emergency and critical patients can effectively guide the treatment of emergency and critical patients, improve the efficiency of medical equipment and the quality of medical care services, thus improving the success rate of patients' rescue and improving the prognosis of patients. In the course of treatment of cardiac arrest, it is very necessary to dynamically monitor the effectiveness of cardiopulmonary resuscitation. PETCO2 is the only noninvasive, rapid and accurate evaluation measure, which has been proved by many studies to be an important indicator that can reflect the effectiveness of cardiopulmonary resuscitation in patients with cardiac arrest.
