\nA 39-year-old homeless man presents to the emergency department for\u00a0cough and fever. He says that his illness has been worsening over the\u00a0past 2 weeks. He originally had dyspnea on exertion and now is short of\u00a0breath at rest. On questioning, he tells you that he lives in a homeless\u00a0shelter when he can, but he frequently sleeps on the streets. He has used\u00a0IV drugs (primarily heroin) \u201con and off\u201d for many years. He denies medical\u00a0history but the only time he gets medical attention is when he\u00a0comes to the emergency department for an illness or injury. On review\u00a0of systems, he complains of fatigue, weight loss, and diarrhea. On examination,\u00a0he is a thin, disheveled man appearing much older than his\u00a0stated age. His temperature is 100.5\u00b0F (38.0\u00b0C), his blood pressure is\u00a0100\/50 mm Hg, his pulse is 105 beats\/min, and his respiratory rate is\u00a024 breaths\/min. His initial oxygen saturation is 89% on room air, which\u00a0comes up to 94% on 4 L of oxygen by nasal cannula. Significant findings\u00a0on examination include dry mucous membranes, a tachycardic but\u00a0regular cardiac rhythm, a benign abdomen, and generally wastedappearing\u00a0extremities. His pulmonary examination is significant for\u00a0tachypnea and fine crackles bilaterally, but no visible signs of cyanosis.\u00a0His chest x-ray is read by the radiologist as having diffuse, bilateral,
\ninterstitial infiltrates that look like \u201cground glass.\u201d
