The increased work of breathing associated with auto-positive end expiratory pressure (PEEP) during mechanical ventilation is due to:

1. Hyperinflation or impaired contractility of the diaphragm. 2. Large alveolar pressure drops required to trigger breaths. 3. Increased volume of the intrathoracic airways. a. 1 and 2 only b. 1 and 3 only c. 2 and 3 only d. 1, 2, and 3
