i-gel supraglottic airway

Created: 23/4/2010
Updated: 7/9/2021
The i-gel is a single use, supraglottic airway management device.

Made from a medical grade thermoplastic elastomer, the i-gel has been designed to create a non-inflatable, anatomical seal of the pharyngeal, laryngeal and perilaryngeal structures while avoiding compression trauma.

The i-gel is currently available in seven sizes.

Size 5, large adult
Size 4, medium adult
Size 3, small adult
Size 2.5, large paediatric
Size 2, small paediatric
Size 1.5, infant
Size 1.0, neonate

Benefits of i-gel

•Made from a unique, soft, gel-like material to allow ease of insertion and reduced trauma.
•Gastric channel designed to improve and enhance patient safety.
•Integral bite-block reduces the possibility of airway channel occlusion.
•Virtually eliminates rotation.
•Reduces the possibility of epiglottis downfolding and obstructing the airway.
•Unique packaging protects the i-gel in transit and ensures that it maintains its anatomical shape.
