Example:
Patient with ARDS, ideal bodyweight (IBW) 80 kg, protective tidal volume 6 ml/kgBW
Fresh Gas O2 Concentration 40%, Fresh Gas Flow 150% of Minute Volume
Expected Minute Volume = IBW x 6 ml/kg x Respiratory Rate
Expected Minute Volume = 80 kg x 6 ml/kg x 14/min = 480 ml x 14 /min = 6.7 L/min
Fresh Gas Flow = Expected Minute Volume x 150%
Fresh Gas Flow = 6.7 L/min x 1.5 = 10.1 L/min  rounded to 10 L/min
Settings on devices with electronic gas mixer:
Fresh Gas Flow = 10 L/min
Fresh Gas O2 Concentration = 40%
Settings on devices with mechanic gas mixer:
O2-Flow = 2.4 L/min
AIR-Flow = 7.6 L/min
