The Ambu AuraOnce features a special 70o curve that carefully replicates natural human anatomy. Molded directly into the tube for additional safety, the unique shape of the mask makes correct insertion fast and easy without putting extra stress on the upper jaw. Moreover, like all Ambu laryngeal masks, AuraOnce has a higher oropharygeal seal pressure to ensure reliable ventilation. AuraOnce has also proven to be particularly useful in establishing a clear airway during resuscitation in profoundly unconscious patients with absent glossopharyngeal and laryngeal reflexes who may need artificial ventilation.
