End-of-breath carbon dioxide is considered the sixth essential vital sign in addition to body temperature, respiration, pulse, blood pressure, and arterial oxygen saturation. In painless examination and short operation, anesthesia is mostly non-intubation, general anesthesia. In this type of anesthesia, a traditional mask or oxygen tube can only provide oxygen, not carbon dioxide monitoring. As a result, doctors may not be able to detect when an anesthetic drug causes respiratory depression, or when a patient is unable to ventilate due to an obstruction of the airway after anesthesia. Expiratory carbon dioxide monitoring] is the standard for monitoring ventilation, so we need to routinely collect and monitor carbon dioxide in this anesthesia mode to avoid serious complications.
Clinical application: Clinical end-expiratory carbon dioxide monitoring is mainly used in clinical environments such as dry anesthesia machine and ventilator application, various respiratory insufficiency, cardiopulmonary resuscitation, severe shock, heart failure and pulmonary infarction, and determination of the position of endotracheal intubation under general anesthesia.
Clinical value of end-exhalation Co2 monitoring :0 For patients with resuscitation tube under general anesthesia, especially critically ill patients, young children and elderly patients, exhalation CO2 monitoring can reduce the rate of respiratory brown hair cows and reduce the rate of secondary gastric tube. @ For patients with intravenous combined anesthesia, carbon dioxide monitoring at the end of breath can detect insufficient ventilation, airway obstruction and respiratory depression earlier than oxygen saturation, so as to reduce the risk of anesthesia and reduce the incidence of negative anesthesia reactions.
Applicable departments: operating room, anesthesiology department, intensive care unit, respiratory department, general surgery, gastroscopy room, obstetrics and gynecology, emergency, etc.
