Introduction: The PERC (Pulmonary Embolism Rule-out Criteria) Rule is utilized by physicians to avoid further testing for pulmonary embolism in patients deemed to be at low risk.

In patients with a low probability of PE who fullfil all eight criteria, the likelihood of PE is low and no further testing is required. All other patients should be considered for further testing with
