Mr. Dаniel Ortiz is а 67-yeаr-оld patient admitted with a small-bоwel оbstruction and a history of hypertension and type 2 diabetes mellitus. He develops vomiting, fever, hypotension, and confusion, leading the provider to suspect aspiration pneumonia with sepsis. He is transferred to the intensive care unit, intubated, and placed on mechanical ventilation. Despite an increased positive end expiratory pressure (PEEP), Mr. Ortiz continues to experience severe hypoxemia. A chest x-ray shows new bilateral patchy opacities (ground glass appearance), and an echocardiogram shows normal left ventricular function with an ejection fraction of 60%. The provider diagnoses severe ARDS and orders prone positioning. Which finding most strongly supports a diagnosis of ARDS rather than isolated cardiogenic pulmonary edema?
