  1. Vteerror global = mean volume error including all conditions of resistance (15 cmH2O/l/s), compliance (20–50 ml/cmH2O) and PEEP (10–15 cmH2O) for both 100% FiO2 and 70% FiO2. Vteerror 100% FiO2= mean volume error including all conditions of resistance (15 cmH2O/l/s), compliance (20–50 ml/cmH2O) and PEEP (10–15 cmH2O) for 100% FiO2, Vteerror 70% FiO2= mean volume error including all conditions of resistance (15–12 cmH2O/l/s), compliance (20–50 ml/cmH2O) and PEEP (10–15 cmH2O) for 70% FiO2. Vteerror C50 = mean volume error including all conditions of 1 resistance (15 cmH2O/l/s), FiO2 (100–70%) and PEEP (10–15 cmH2O) for a compliance of 50 ml/cmH2O. teerror C20 = mean volume error including all conditions of resistance (15 cmH2O/l/s), FiO2 (100–70%) and PEEP (10–15 cmH2O) for a compliance of 20 ml/cmH2O, Mean PEEP 10 = mean PEEP measured when PEEP was set at 10 cmH2O including all conditions of resistance (15 cmH2O/l/s) and compliance (20–50 ml/cmH2O) for both 100% FiO2 and 70% FiO2. Mean PEEP 15 = mean PEEP measured when PEEP was set at 15 cmH2O including all conditions of resistance (15 cmH2O/l/s) and compliance (20–50 ml/cmH2O) for both 100% FiO2 and 70% FiO2
  2. *p < 0.005 when comparing each transport ventilator with the Engstrom ICU ventilator (ANOVA test: global F was significant)
