A novel jaw thrust device (JTD) was tested against oropharyngeal and nasopharyngeal airways in anaesthetised patients. The JTD enabled effective ventilation with less airway resistance than the traditional airways, and so provided greater tidal volumes during pressure controlled ventilation. It fits into the mouth, keeping the mouth open and the jaw thrusted forward, and has a standard sized connector for attachment to ventilation devices.
