Tidal Volume delivery in volume control ventilation in static conditions. a The histogram represents the mean expired volumes measured for each ventilator according to the three Vt set in 100% FiO2. The average was computed over the four conditions of resistance (15 cmH2O/l/s), compliance (20–50 ml/cmH2O) and PEEP (10–15 cmH2O). The three tidal volumes tested were chosen to cover 6 ml/kg PBW, with 350, 450 and 550 ml corresponding to 6 ml/kg PBW for respectively 58, 75 and 92 kg PBW. Limits of acceptable ventilation are displayed with dotted lines and defined as a volume change within ± 0.5 ml/kg PBW, which corresponds to a Vt between 5.5 and 6.5 ml/kg PBW. b The histogram represents the mean expired volumes measured for each ventilator according to the three Vt set in 70% FiO2. The average was computed over the four conditions of resistance (15 cmH2O/l/s), compliance (20–50 ml/cmH2O) and PEEP (10–15 cmH2O)
