Answer to Question 1

ANS: D
The presence of auto-PEEP results in the underestimation of mean alveolar pressure when mean airway pressure is being monitored to reflect mean alveolar pressure. An increase in mean alveolar pressure due to auto-PEEP may exacerbate the hemodynamic effects of positive pressure ventila-tion and increase the likelihood of barotrauma in a manner similar to that seen with the applica-tion of PEEP.

Answer to Question 2

ANS: B
Patients receiving mechanical ventilation for obstructive airways disease have a large degree of inhomogeneity in the emptying of lung units, and auto-PEEP can develop even at relatively low-minute ventilation. Auto-PEEP is common in mechanically ventilated patients with high-minute ventilation and thus occurs in some patients with ARDS.

Glaucoma is a leading cause of blindness. As of yet, there is no cure. Everyone is at risk, and there may be no warning signs. It is six to eight times more common in African Americans than in whites. The best and most effective way to detect glaucoma is to receive a dilated eye examination.
