The X66 Anesthesia System administers inhalation anesthesia and monitors patients’ vital signs. It integrates seven vital-sign-monitoring modules: anesthesia depth monitoring, EEG monitoring, various anesthetic-gas monitoring, blood-oxygen detection, ECG monitoring, blood-oxygen monitoring, and pulse-rate monitoring. It can automatically provide anesthesiologists with alarms and suggestions for the next steps according to the patient’s ventilation parameters and vital-sign parameters. The X66 supports anesthesiologists by providing them recommendations and reducing the intensity of their work.
