anesthesia machine is a piece of medical equipment used in the
administration of anesthesia. The machine delivers calibrated
mixtures of anesthesia gases and oxygen to the patient to
sustain anesthesia, while also providing patient monitoring
capabilities to allow the anesthesiologist or technician caring
for the patient to make adjustments as necessary during the
procedure. The cost of the equipment varies depending on the
available features and the manufacturer, but they tend to be
quite expensive as they are delicate and critical devices for
the operating room setting. The anesthesia machine can hook up
to wall supplies of oxygen and other gases, as well as reserve
cylinders kept for emergencies. When an anesthesiologist
develops an anesthesia plan after meeting with the patient and
the surgeon, the parameters of the plan are entered into the
machine and the anesthesiologist makes the appropriate
connections to supply the machine with the needed gases.
