ETCO2 in Emergency Prognosis

End-tidal carbon dioxide has great clinical value in the field of emergency. End-tidal carbon dioxide monitoring is non-invasive, real-time, and convenient. In the emergency department where every second counts, it is an indispensable monitoring method. It is an essential monitoring tool in emergency departments where every second counts. Emergency prognosis can predict the possible course or outcome in advance, improve the efficiency of emergency treatment, and reduce unnecessary waste of medical resources.

The clinical value of end-tidal carbon dioxide monitoring in predicting the prognosis of patients in the emergency room is that it is a non-invasive, reliable and quickly reflective monitoring index that endangers the life of patients for emergency medical staff. Non-invasive end-tidal carbon dioxide refers to the maximum instantaneous CO2 concentration exhaled at the end of the breath, reflecting a series of physiological processes in which the metabolized CO2 is excreted through the lungs. The normal value of the human body is 35-45mmHg. Studies have pointed out that end-tidal carbon dioxide is the "sixth major vital sign" for pre-hospital evaluation of patients' in-hospital death and metabolic disorders, and it can reflect the prognosis of critically ill patients to a certain extent. Here, we recommend you Ekingst end tidal carbon dioxide detector.

End-tidal carbon dioxide is an essential monitoring method in clinical anesthesia. Since 1997, ETCO2 has been included in the routine detection items during anesthesia by ASA. ETCO2 has important value in post-anesthesia recovery room, intensive care unit, emergency department, and surgery. End-tidal carbon dioxide can not only reflect the abnormal conditions of the human body in respiration, circulation and metabolism to a certain extent. The Capnograph monitor produced by Kingst is small in size, easy to measure, and can quickly obtain measurement results without causing any damage to the patient. In the case of normal ventilation/blood flow ratio, it can accurately reflect the blood carbon dioxide partial pressure, and can effectively replace blood gas analysis in certain occasions. Using ETCO2 for initial condition assessment provides the possibility to quickly predict the prognosis of spontaneously breathing patients. Moreover, the correlation between arterial blood carbon dioxide and end-tidal carbon dioxide is high. When the pulmonary blood flow and pulmonary ventilation are stable, V/Q tends to be stable. The value and waveform of end-tidal carbon dioxide can effectively represent the arterial blood carbon dioxide.

End-tidal carbon dioxide monitoring is beneficial to improve the ability to predict the prognosis of emergency patients and the quality of care. At present, many studies have shown that end-tidal carbon dioxide has a certain predictive effect on the death risk of patients. The leading causes of death in emergency department patients are hypoperfusion, hypoventilation, and metabolic disturbances. There was a significant negative correlation between end-tidal carbon dioxide and LAC level, and the value of end-tidal carbon dioxide decreased with the increase of LAC, but was positively correlated with HCO3 level.

The end-tidal partial pressure of carbon dioxide can effectively predict the quality of cardiopulmonary resuscitation and rescue prognosis of patients with cardiac arrest, and can accurately evaluate the prognosis of patients. The main factors of end-tidal partial pressure of carbon dioxide are aerobic metabolic rate, alveolar ventilation, lung perfusion, and cardiac output. When the patient's lung ventilation and perfusion are abnormal (such as in cardiac arrest or pulmonary embolism), the difference between the end-tidal partial pressure of carbon dioxide and the partial pressure of carbon dioxide in the arterial blood increases. In view of this, in theory, monitoring end-tidal partial pressure of carbon dioxide can determine whether CPR is effective in patients with cardiac arrest.
