2. Fig 1
Effect of FGF on the volume error across four anaesthesia ventilators for a set tidal volume of 500 ml (with end-inspiratory pause) and compliance of 60 ml cm−1 H2O. Resistance 5 cm−1 H2O litre−2 on ZEEP (blue bars) and PEEP (green striped bars) 10 cm H2O. For each ventilator, the left vertical bar is for low FGF, the middle vertical bar for medium FGF, and the right vertical bar for high FGF. The bars represent the mean values. †P < 0.05 vs the three other ventilators at a given FGF rate. *P < 0.05.

3. Fig 2
Effect of end-inspiratory pause on the volume error at a different FGF in three anaesthesia ventilators at compliance 60 ml cm−1 H2O and resistance 20 cm−1 H2O litre−2 for three set tidal volumes (VT). The bars represent the mean values for no pause (blue) and pause (green striped). * P < 0.05 vs pause.
