2. Fig 1
The laryngeal tube (VBM, Germany). The black lines on the tube near the connector indicate adequate depth of insertion when aligned with the teeth. The line indicates a distance of 10 cm.

3. Fig 2
The laryngeal tube in place. When inserted, the device lies along the length of the tongue and the distal tip is positioned in the hypopharynx. The cuff is inflated until the intracuff pressure reaches 60 cm H2O.

4. Fig 3
The minimum airway pressure at which gas leaked around the cuff of the test device. Symbols are displaced slightly on the Y axis if they are the same values. Lines join measurements with the two devices in the same subject.
