Algorithm reflecting the clinical features of a patient with COPD presenting with increased respiratory symptoms and suspected pulmonary embolism (PE). Recommendations are on the basis of Konstantinides and colleagues (35) and Couturaud and colleagues (36). *PE probability assessed using Geneva or Wells scores. COPD = chronic obstructive pulmonary disease; CRP = C-reactive protein; CTPA = computed tomography pulmonary angiogram; DVT = deep-vein thrombosis; ECOPD = exacerbation of chronic obstructive pulmonary disease; GDMT = guideline-directed medical treatment; WBC = white blood cell count.
