Limb-O Circuit



Limb-O is a single tube anesthesia breathing circuit. Unlike coaxial systems, the Limb-O is a divided tube, utilizing a flexible septum running the length of the tube. There are many advantages to this design, which combines reduced weight per meter and lower compressible volume loss, with a supple feel and drape. There is also the possible added benefit of less torque on the patient interface. Estimates suggest patients can lose up to 15% of their heat because of cold, dry anesthetic gases. Limb-O effectively transfers heat from the expiratory to inspiratory side of the circuit, helping to reduce the patients energy demands and aiding in their ability to remain normothermic. Limb-O's innovative tubing design supports clinicians' efforts in the delivery of a general anesthetic.
