- Primary Outcome Measures
Name Time Method Cuff pressure - the air pressure in the cuff of the airway device, measured by connecting a manometer to the cuff inflation valve.[at the time of LMA placement];the seal pressure - the pressure in the lungs at which air begins to leak around the edges of the LMA, measured by occluding the airway valve, allowing airway pressures to slowly rise, and noting the pressure at which air leak is heard around the airway device[at the time of LMA placement];the fibreoptic grading - an assessment of how well the LMA is placed, gained from visual inspection of the larynx through the LMA using a camera. An image of the larynx will be recorded and later graded according to an established fibreoptic grading system.[at the time of LMA placement]
- Secondary Outcome Measures
