Answer to Question 1

ANS: C
Most clinicians consider small leaks (<20) acceptable and even desirable as an added safety pressure-release site and as assurance that no significant inflammation is present around the tube.

Answer to Question 2

ANS: C
Nearly complete equilibrium of alveolar pressures occurs in 3-5 time constants in infant lungs with normal mechanics.
