Answer to Question 1

ANS: B
The figure shows a low-compliant unit, which has a short time constant. This means it takes less time to fill and empty and will require more pressure to achieve a normal volume. Lung units that require more time to fill are high-resistance units. Lung units that require more volume to fill than normal are high-compliance units.

Answer to Question 2

ANS: B
Raw = (PIP  Pplateau)/flow and flow is in L/sec.
