Ambu AuraOnce Disposable Laryngeal Mask - Available in eight convenient sizes, AuraOnce from Ambu is the ideal alternative to a traditional face mask for achieving and maintaining control of the airway during routine and emergency anaesthetic procedures in fasted patients. It is also an excellent option when unexpected difficulties arise in connection with airway management. The Ambu AuraOnce features a special 70 degree 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.
