Answer to Question 1

ANS: B
A malfunction of the pilot valve will cause a leak. This will not allow for the endotracheal cuff to maintain appropriate pressure to seal the airway.

ANS: C
The ASTM and the ISO recommend that manual resuscitators be capable of delivering a frac-tional inspired oxygen of 0.85 with an oxygen flow of 15 L/min.
