Answer to Question 1

ANS: D
Decreases in cardiac output can occur in normovolemic patients with levels of PEEP >15 cm H2O.

Answer to Question 2

ANS: A
Patients with stiff lungs (as in ARDS or pulmonary fibrosis) are less likely to experience hemo-dynamic changes with high pressures, because less of the alveolar pressure is transmitted to the intrapleural space. Patients with compliant lungs (as in emphysema) or with stiff, noncompliant chest walls (as in kyphoscoliosis and extensive chest wall burns) are more likely to have higher intrapleural pressures with PPV and experience more pronounced cardiovascular effects.
