Low flow anesthesia

Abstract

Historically, rebreathing anesthesia systems were invented to reduce the consumption of volatile anesthetics and to optimize respiratory gas conditioning. However, the industry is still modifying and optimizing the rebreathing circle systems. Most of the modern anesthesia machines today use a rebreathing circle system and are constructed for the use of very low fresh gas flows during inhalational anesthesia. Here we present a practical approach to performing metabolic-flow anesthesia with newer anesthesia agents using pure oxygen as the gas carrier gas.
