A 57-year-old man is admitted to the hospital because of respiratory failure due to an exacerbation of chronic obstructive pulmonary disease. Thirty-six hours after intubation and initiation of mechanical ventilation, his oxygen saturation suddenly decreases from 96%
to 78% without changing any ventilator settings. His FIO 2 is 40%, ventilatory rate is 12/min, and tidal volume is 800 mL. There is no positive end-expiratory pressure. He is conscious and in mild respiratory distress. His temperature is 39.2°C (102.6°F), blood pressure is 110/70 mm Hg, pulse is 1201min, and respirations are 381min. Examination shows no inflammation at the skin site where the central catheter was inserted. Breath sounds on the left are present, but decreased in volume. Breath sounds on the right are absent, and there is hyperresonance over the right hemithorax. There is no dullness to percussion on either side. Cardiac examination shows distant heart sounds but no rubs, murmurs, or gallops. An ECG shows sinus tachycardia and diffuse low voltage. Which of the following is the most likely explanation for these findings?
p A) Hemothorax
O B) Improper placement of the endotracheal tube
O C) Mucous plug
O D) Pericardial tamponade
p E) Pneumothorax
0 F) Sepsis
