Which of the following complications has been associated with the use of PEEP in patients with ARDS?

a. Lung infection
b. Reduced cardiac output
c. Hepatic failure
d. Myocardial infarction

Question 2

What mode of mechanical ventilation is designed to optimize ventilation by reducing alveolar collapse while using small tidal volumes in patients with ARDS?

a. Inverse ratio ventilation
b. High-frequency ventilation (HFV)
c. Intermittent mandatory ventilation
d. Airway pressure-release ventilation

Answer to Question 1

ANS: B
Because the primary goal of mechanical ventilation is to provide adequate oxygenation at safe levels of FiO2 while maintaining adequate DO2 to the body, the inverse relation between PEEP and cardiac output must be considered.

Answer to Question 2

ANS: B
HFV was designed to simultaneously maintain adequate ventilation and reduce alveolar collapse through ventilation with high expiratory lung volumes and rapid (up to 300 breaths/min), small tidal volumes (3 to 5 ml/kg).
