Answer to Question 1

ANS: C
1 mm Hg = 1.36 cm H2O
1 kPa = 7.5 mm Hg
1 Torr = 1 mm Hg
1 atm = 760 mm Hg = 1034 cm H2O

Answer to Question 2

ANS: B
Use the graph to determine the PIP (34 cm H2O) and the Pplateau (20 cm H2O). Convert the flow into L/sec (70 L/min/60 = 1.2 L/sec). Then, Raw = (PIP  Pplateau)/flow.
