Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will be multi-centre and prospectively planned. All patients who undergo contrast-enhanced computed tomography in the emergency department with a preliminary diagnosis of pulmonary embolism and who do not meet the exclusion criteria will be included in the study. Informed consent will be obtained from all patients prior to the study. Patients included in the study will undergo bedside ultrasound to assess bubble time, right ventricle-left ventricle ratio, presence of a septal defect, and tricuspid insufficiency, and the diagnostic value of these findings will be evaluated. The bedside ultrasound will be part of the emergency department critical care examination, will not incur any costs for the institution, and will be performed and evaluated by an emergency medicine specialist and assistant.
