title: Storage capacities of the laryngeal mask and laryngeal tube compared and their relevance to aspiration risk during positive pressure ventilation.
abstract: Supraglottic airways used for positive pressure ventilation run the occasional risk of regurgitated liquid entering the lungs (aspiration). A dynamic model described here shows that the laryngeal tube has a larger liquid storage capacity between the two cuffs than the bowl of the laryngeal mask, with a consequent smaller aspiration risk.
