This device can be inserted blindly through the oropharynx into the hypopharynx to create an airway during anaesthesia and cardiopulmonary resuscitation so as to enable mechanical ventilation of the lungs.

[2] Various studies have shown that insertion and use of the standard tracheal tube is easy, providing a clear airway in the majority of cases.

[2] Several studies describe the usefulness of the device in securing a difficult airway, even in cases where insertion of the laryngeal mask had failed.

[13][14] The double-lumen laryngeal tube-Suction II, with the possibility of placing a gastric tube, has been found to have distinct advantages over the standard laryngeal tube and has been recommended as a first-line device to secure the airway in emergency situations when direct laryngoscopy fails in neonates and infants.

[19] The European Resuscitation Council, in its 2005 guidelines for advanced life support (ALS), accepts its use as an alternate airway device for medical personnel who are not experienced in tracheal intubation.
