Figure 2: (a) Schematic diagram showing functioning of ventilator with area of obstruction shown. (b) Hose of the pressure monitoring line with filter occluded by an artery forceps. (c) Ventilator screen snap shot showing peak airway pressure of 16 cm H2O, with a set tidal volume of 1000 mL and pressure limiting alarm set at 15 cm H2O. (d) Ventilator screen snap shot after occluding pressure monitoring line showing a peak airway pressure of 27 cm H2O and continuous pressure alarm, with a delivered tidal volume of 378 mL against set 1000 mL
