Comparison of Efficacy of Two Supraglottic Airway Devices: I-gel and the Self-pressurized Air-q in Elderly Patients

"The i-gel airway is a supraglottic airway management device made of thermoplastic elastomer, which is soft, gel-like, and transparent.~The i-gel has evolved as a device that accurately positions itself over the laryngeal framework, providing a reliable perilaryngeal seal, and therefore no cuff inflation is necessary."

The self-pressured air-Q is a supraglottic airway management device The intracuff pressure of air-Q dynamically equilibrates with the airway pressure and adjusts to the patient's pharyngeal and periglottic anatomy, potentially providing improved airway fit and seal.
