I-gel is a truly unique, single use, supraglottic airway management device. Made from a medical grade thermoplastic elastomer, i-gel has been designed to create a non-inflatable, anatomical seal of the pharyngeal, laryngeal and perilaryngeal structures whilst avoiding compression trauma. I-gel is indicated for use in securing and maintaining a patient airway in routine and emergency anaesthetics of fasted patients, during spontaneous or intermittent positive pressure ventilation, and during resuscitation of the unconscious patient, by personnel who are suitably trained and experienced in the use of airway management techniques and devices i-gel is currently available in three adult sizes and is supplied in an innovative, colour-coded polypropylene 'protective cradle'. The i-gel supraglottic airway comes in a size 4 which is a size medium.
