Fig 1 Proximal (dotted line) and distal (solid line) airway pressure (Paw) in patient no. 6 during increasing obstruction of the airway: Period A: apnoea during zeroing of both pressure sensors; period B: beginning of expansion of endosonography probe balloon; period C: complete occlusion of the airway.

Fig 2 Proximal and distal Paw during 0%, 50% and 90% obstruction of the airway and a driving pressure of 2.0 atm (upper segment) and 3.0 atm (lower segment). Values are expressed as mean±sd; *Significantly different from Paw without obstruction (P<0.025), †Pressure amplitude significantly different from that without obstruction (P<0.025).
