Anaesthesia Machine | How Its Works

An anesthesia machine is a system of components that together control and manage the delivery of gasses to the patient. Gasses such as oxygen and nitrous oxide are delivered in cylinders. The machine then uses a system of flow control valves and flow meters to regulate the supply.

As with many systems, anaesthesia machines are modular. Each component of the machine is joined to the next by a series of pipes and tubing. These can be of different materials. For example, anesthesia machines may use high-density nylon tubing, or copper piping. A push fit metal ‘T’ junction is used to connect the two tubings. This tubing is less prone to breakage.
