A 40yo male presents to the emergency department with the chief complaint of shortness of breath (SOB). His past medical history (MHx) is remarkable for hypertension (HTN) and diabetes mellitus II (DMII). On examination, his oxygen saturation on room air is 87%, blood pressure 160/100 mmHg, and pulse rate is 93/min. His arterial blood gas on room air shows pH 7.44, PCO2 35 mmHg, PO2 55 mmHg. Assume that the RQ is 0.8. Given arterial pO2 and alveolar pO2, the following disease states are plausible...
