A 94-yeаr-оld mаle pаtient was admitted tо the intensive care unit fоr acute hypoxemic respiratory failure secondary to influenza A with superimposed Staphylococcus aureus pneumonia. The patient required norepinephrine, vasopressin, and angiotensin 2 for hemodynamic stability. The patient improved with IV antibiotics, aggressive pulmonary toilet, and supportive care and no longer required oxygen support. Given his improvement, the patient was transferred to the general medical floor for continued medical management. Later at night, a rapid response was called for hypoxemia, and increased oxygen requirement as the patient developed acute shortness of breath. He was found to have an oxygen saturation of 82%. The examination showed tachycardia of 110/min. The patient was placed on 15 liters of oxygen supplementation, but no improvement was seen in oxygen saturation levels. A chest x-ray was negative for any acute pathology, and daily labs showed the following: WBC 12.0, hemoglobin 11.2, hematocrit 27.0, platelets 250, sodium 130, chloride 100, bicarbonate 24, blood urea nitrogen 15, serum creatinine 1.3, PT/INR within a normal range. What should be the next step in the evaluation of this patient?
