Ambu® AuraFlex™ is so flexible that it can easily be taped well away from the surgical field, improving surgical access without any loss of seal. The flexible tube is also reinforced with kink-free wire, which eliminates the risk of airway tube occlusion. Furthermore, the integration of pilot tube in the airway tube makes handling and insertion easy and dramatically reduces the risk of cutting the pilot tube during surgery. . The Different Sizes are 1, 1.5, 2, 2.5, 3, 4, 5, 6.
