The Traditional Circle Breathing System
{"Image DocumentName": "The Traditional Circle Breathing System", "Image ImageDescription": "The traditional circle system, referred to as either a universal F or a single-limb circuit. The circle system prevents rebreathing of carbon dioxide by use of carbon dioxide absorbents but allows partial rebreathing of other exhaled gases. The extent of rebreathing of the other exhaled gases depends on the arrangement of the breathing circuit components and the fresh gas flow rate. A circle system can be semiopen, semiclosed, or closed, depending on the amount of fresh gas inflow. A semiopen system has no rebreathing and requires a very high flow of fresh gas. A semiclosed system is associated with some rebreathing of exhaled gases and is the most commonly used application in anesthesia.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
