All procedures that involve anesthesia require reliable anesthesia monitors to maintain patient safety. There are several types of anesthesia monitors and related medical equipment in use. The choice of appropriate monitoring equipment depends on the type of cases to be performed in a particular setting.
Anesthesia monitors can be characterized as devices that primarily monitor the delivery of substances (gases, drugs and fluids) to the patient, or instruments that measure and display the physiological state of the patient. These devices may be part of a multivariable monitor, an anesthesia machine / anesthesia workstation, or a separate console. Alarms incorporated into monitoring systems detect and alert to out-of-range variables or conditions.
