Answer to Question 1

ANS: B
The PaO2/FIO2 for answer A is 317, which shows no ALI or ARDS. The PaO2/FIO2 for answer B is 125; this is an indication for PEEP therapy (PaO2/FIO2 < 200 for ARDS). The compliance for answers C and D is 50 mL/cm H2O and 53 mL/cm H2O, respectively. These compliances are normal for intubated patients.

Answer to Question 2

ANS: B
Approximately 15 minutes after an increase in PEEP, all ventilatory and available hemodynamic parameters are measured and calculated.
