More than 1.5 million patients are diagnosed with a pleural effusion annually in the United States (1). Pointofcare ultrasound is commonly used to categorize pleural effusions radiologically as simple, complex septated, complex nonseptated, or homogeneously echogenic; however, the utility of ultraso...
