Anaesthetic machine

Anaesthetic Machine

The Anaesthetic Machine (pronounced: an-uh-sthet-ik muh-sheen) is a complex device used primarily in the medical field to deliver a mixture of anaesthesia and oxygen to patients undergoing surgical procedures.

Etymology

The term "Anaesthetic Machine" is derived from the word "anaesthesia", which comes from the Greek words "an" (without) and "aesthesis" (sensation), and the word "machine", which originates from the Latin word "machina", meaning a structure or device.

Function

The primary function of an Anaesthetic Machine is to provide a continuous and accurate supply of medical gases (like oxygen and nitrous oxide), mixed with a precise concentration of anaesthetic vapour. This allows the anaesthesiologist to maintain the patient in the desired level of anaesthesia.

Components

The Anaesthetic Machine consists of various components, including:

Gas Supply: This includes cylinders or pipelines that supply oxygen, nitrous oxide, and other medical gases.
Vaporizer: This device converts liquid anaesthetic into its vapour state.
Flowmeter: This measures the flow rate of gases.
Breathing System: This delivers the anaesthetic gases to the patient.
Ventilator: This mechanical device supports or replaces spontaneous breathing.
Monitoring Equipment: This monitors the patient's vital signs and the concentration of gases.

Related Terms

Anaesthesiologist: A medical professional trained in anaesthesia and perioperative medicine.
