How can i-gel create a satisfactory perilaryngeal seal when it doesn have an inflatable cuff?
The i-gel is a truly anatomical device. The soft, non-inflatable cuff fits snugly onto the perilaryngeal framework, mirroring the shape of the epiglottis, aryepiglottic folds, piriform fossae, peri-thyroid, peri-cricoid, posterior cartilages and spaces. Each receives an impression fit, thus supporting the seal by enveloping the laryngeal inlet. The seal created is sufficient for both spontaneously breathing patients and for IPPV.
