The PERC Rule for Pulmonary Embolism Rules out PE if no criteria are present and pre-test probability is ≤15%.

Mar 10, 2014 · However, your PE prevalence must be 7% or less (essentially a Wells < 2) before the PERC rule can be applied to patients presenting to ED with suspected PE in conjunction with clinical judgment to identify patients with a prevalence of PE that is below the 1.8% test threshold proposed by Kline.

Does use of the pulmonary embolism rule-out criteria (PERC) in emergency department patients with low clinical probability of pulmonary embolism (PE) safely exclude the diagnosis of PE? In this cluster-randomized crossover noninferiority trial that ...

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 sensitive D-dimer or imaging.

Jun 15, 2014 · PERC (Pulmonary Embolism Rule-Out Criteria) is a set of criteria established for patients with chest pain or dyspnea in outpatient settings (ie. primary care settings or emergency departments). PERC Criteria are defined as the following: Age <50 years; HR <100 BPM; Oxygen Saturation ≥ 95%; No hemoptysis; No estrogen use; No prior DVT or PE

This PERC calculator (Pulmonary Embolism Rule-out Criteria) gives you a quick look at the PERC criteria, which can help you determine if the patient is likely to have a pulmonary embolism.

if clinical suspicion of PE is low[1], consider using the pulmonary embolism rule-out criteria (PERC) to help determine whether any further investigations for PE are needed [1] The clinician estimates the likelihood of PE to be less than 15% based on the overall clinical impression and other diagnoses are feasible.

The PERC rule criteria are used to help the clinician to do a bedside assessment to determine if a patient is at "low risk" for pulmonary embolism and does not warrant additional diagnostic evaluation, including a D-dimer.

Jan 19, 2024 · The pulmonary embolism rule-out criteria (PERC) may be utilised to negate the need for further pulmonary embolism (PE) workup in patients who are deemed low risk for PE but in whom the diagnosis is being considered 1.

The PERC rule is used to rule out pulmonary embolism in those patients where the clinical gestalt is that they are low risk (ie <15% risk of pulmonary embolism). Pulmonary embolism can be ruled out if none of the following features are identified: Age ≥50 years; Heart rate ≥100 bpm; Oxygen saturation <95%; Hemoptysis; Estrogen use; Prior ...
