Which of the following ventilator parameters would result in the highest mean airway pressure?
a. PIP = 30 cm H2O; PEEP = 10 cm H2O; TI = 0.5 sec; TCT = 5 sec
b. PIP = 50 cm H2O; PEEP = 10 cm H2O; TI = 0.5 sec; TCT = 5 sec
c. PIP = 30 cm H2O; PEEP = 15 cm H2O; TI = 0.5 sec; TCT = 5 sec
d. PIP = 50 cm H2O; PEEP = 10 cm H2O; TI = 0.5 sec; TCT = 5 sec
ANS: C
MAP = (PIP-PEEP) ? (Inspiratory time/Total cycle time) + PEEP
