Th × 100. Inspiratory trigger = 5 L/min; muscular pressure = 10 cmH2O; PEEP = 5 cmH2O; respiratory rate = 20/min. Respiratory system mechanics, normal: resistance (R) = 10 cmH2O/L/s and compliance (C) = 60 mL/cmH2O; obstructive: R = 20 cmH2O/L/s and C = 60 mL/cmH2O; restrictive: R = 10 cmH2O/L/s and C = 30 mL/cmH2O; and mixed: R = 20 cmH2O/L/s and C = 30 mL/cmH2O
