The patient was then weaned and able to maintain oxygen saturation of 93% on 5 L via nasal cannula. Cell counts and electrolytes were within normal limits. The patient was negative for Flu A/B and had a negative respiratory viral panel. Chest X-ray obtained showed nonspecific bibasilar airspace disease (Fig. 1 ). Of note, the patient's D-dimer was elevated to 2574 and CT imaging was ordered to evaluate for pulmonary embolism. CTA of the chest with PE protocol revealed bibasilar opacities. The patient was admitted to the progressive care unit for respiratory support and COVID-19 rule out.
