Background

Anesthesia is effected by administering drugs via veins, intramuscular injection, inhalation, etc. which act on the central nervous system. In general, intravenous anesthesia is performed by inputting an anesthetic into a human body through an injector, and the pain of a patient can be increased by performing anesthesia in an injection mode; patients who fear injection also often feel fear due to injection and then generate mental stress, and the serious syncope can be caused. In the anesthetic injection process, the phenomenon of patient incompatibility often appears, leads to medical personnel's work difficulty, and inefficiency, and then influences the normal clear of follow-up operation.

Inhalation anesthesia is an anesthesia mode of using gas anesthetic to be inhaled into a human body from a respiratory tract, and has the characteristics of no wound and no pain; the safety is high, the controllability is strong, and the fear of patients can be reduced, so that the medicine is welcomed. However, inhalation anesthesia, which is currently performed by inhalation through an oral nasal mask similar to an oxygen mask, is not effective for oral surgery requiring continuous anesthesia. In this case, most of the inhalational anesthesia is inhaled by using an oxygen tube or a nasal catheter. In many cases, the movement and leakage of anesthetic may occur due to the unfirm fixation caused by too shallow depth, or the nasal cavity may be uncomfortable due to too deep depth, and the desired anesthetic effect may not be achieved.

In addition, it is often necessary to keep the respiratory state of the patient after the start of anesthesia, i.e., whether the patient is in a normal state for gas exchange in the body during anesthesia, to prevent respiratory depression during anesthesia and surgery, which can have serious consequences. End tidal carbon dioxide concentration monitoring is the gold standard for intraoperative ventilatory monitoring.
