Endobronchial ultrasound is feasible and safe to diagnose pulmonary embolism in non-transportable SARS-CoV-2 ARDS patients requiring extracorporeal lung support

Table 1 Patients’ characteristics and diagnostic correspondence between Endobronchial Ultrasound (EBUS) and Computed tomography pulmonary angiography (CTPA)
