Abstract
Systems, methods, and apparatus for removing volatile anesthetics from an anesthesia or ventilation system to minimize the effects of malignant hyperthermia in susceptible patients. According to one aspect of the present invention, a system for removing volatile anesthetics is provided. A first filter component placed in fluid communication with an inspiratory limb of an anesthesia or ventilation system such that volatile anesthetics will pass through the first filter component during operation of the anesthesia or ventilation system. A second filter component is operably coupled to the expiration port of the anesthesia or ventilation system such that gases passing through the expiratory limb of the anesthesia or ventilation system pass through the second filter component. The first filter component and second filter component are adapted to effectively remove volatile anesthetics passing through the respective filters.
