Answer to Question 1

ANS: A
Recently, CPAP units have been developed that automatically adjust the airway pressure in re-sponse to apnea, hypopnea, airflow limitation, or snoring. This auto-CPAP may result in lower effective pressures and better patient compliance, while eliminating the need for sleep-study ti-tration. Alternatively, CPAP may be titrated against pulse oximetry data (Figure 56-10). In this case, the goal is to use the lowest CPAP pressure that will prevent arterial desaturation (SpO2 < 90).

Answer to Question 2

ANS: D
Adjusting the straps (while maintaining a good mask seal) can help to prevent irritation. In addi-tion, the patient interface should be cleaned daily to remove dirt and facial oils. Even with proper care, most interfaces such as masks harden over time, causing problems with irritation and leaks. For this reason, masks and nasal pillows should be replaced approximately every 3 to 6 months, or sooner if leakage or discomfort occur.
