Abstract
Transducers, regulators, and medical gas cylinders are ubiquitous in anesthesia, and this chapter examines their principles and most common uses. Transduction is the conversion of a signal from one form of energy to another, a principle which underlies many of the commonly used monitoring devices in anesthesiology. Multiple safety features exist as various points in the anesthesia machine to ensure that gases are administered to the patient in a safe and manageable way. Among these are various pressure regulators that ensure that gases, from either a master supply or a gas cylinder, enter the patient circuit at physiologically safe pressures. Gas cylinders themselves contain many safeguards, including unique attachments to the anesthesia machine, and distinct color codes unique to each gas.
