Answer to Question 1

ANS: A
With mixed apnea, there is cessation of airflow at the nose and mouth. Initially, there is an ab-sence of respiratory effort, which is the central component, followed by at least 2 cycles of res-piratory effort with continued absence of airflow, which is the obstructive component.

Answer to Question 2

ANS: C
The polysomnographic tracing of a patient exhibiting obstructive sleep apnea shows paradoxical movement of the chest and abdomen and recurrent complete airway obstructions, leading to ox-ygen desaturation.
