Abstract
The Ambu Aura-I is a great alternative to the endotracheal tube for attaining and maintaining airway control during elective and emergency operations in patients who are candidates for a supraglottic airway or when alternative options aren’t accessible or when other attempts to insert a secure airway have failed. It offers a number of advantages: anatomically correct curve is built-in for quick and easy implantation,standard endotracheal tubes can be used through it for intubation, the reinforced tip prevents the plugging of the upper esophageal sphincter and prevents it from folding over during establishment,occlusions are prevented by the bite resistance in the connector block, depth markers make it easy to keep track of the right position, the pilot balloon determines the mask size and offers a tactile indicator of the degree of inflation as well as navigation markers for the procedure of guiding the flexible scope
