PY - 2014 T2 - Anesthesiology Core Review: Part One Basic Exam AB - As gas is supplied from a central supply or a cylinder, it passes through a fail-safe valve while traveling toward the flowmeters located in the anesthesia machine. The meters are equipped with a proportioning system and specially designed to prohibit a hypoxic gas mixture from being delivered to the patient. After the meters, the gas enters a manifold or mixing chamber, where it passes through vaporizers and continues to the common gas outlet, and eventually to the patient. Several safety features in the anesthesia breathing system ensure that the patient receives adequate oxygen supply: (1) fail-safe valve; (2) rotameter; and (3) proportioning device.
