Monitors, Physiologic, Respiration, Respiratory/Anesthetic Gas, Intraoperative, Mass Spectrography
Definition : Monitors designed to simultaneously and continuously sample, measure, and display the concentrations of respiratory and anesthetic gases using a mass spectrograph during surgical procedures using general anesthesia (i.e., intraoperative). These monitors typically consist of a gas sampler, a mass spectrometer, electronic circuits, and a display.; tThe monitors require use of a disposable kit including tubes, adapters, and a filter for proper functioning. Mass spectrography respiratory/anesthetic gas monitors can identify and quantify simultaneously all common respiratory and anesthetic gases (e.g., oxygen, carbon dioxide, nitrous oxide, isoflurane, desflurane, and sevoflurane) and also nitrogen (N2). The quantification of nitrogen may aid in the diagnosis of intraoperative air embolism during surgery and in assessing the integrity of the delivery system. Mass spectrography monitors can be used as a dedicated single-patient monitor or as a part of a computerized system for many patients in different operating rooms on a time-sharing basis.
