Abstract
In order to visually monitor all aspects of a breathing circuit, a visually monitored anesthesia breathing circuit is disclosed. The circuit includes a transparent absorber having a disposable single use cartridge with particulate carbon dioxide absorbent material therein. The disposable single use cartridge is also formed of a transparent material and is removably positioned within the absorber. The circuit also includes a visual indicator associated with the disposable single use cartridge for indicating the extent of depletion of carbon dioxide absorption potential of the carbon dioxide absorbent material. The absorber includes an expiratory valve in communication with the disposable single use cartridge and an inspiratory valve in communication with the absorber. The circuit further includes fittings for delivering an anesthetic and/or oxygen to a patient in a metered flow. With this arrangement, the circuit also has a humidifier and an overflow valve in communication with the absorber for connection to an operating room scavenger system.
