Confirmed acute PE · adults ≥18

Start with the patient.

Record symptoms and calculate validated clinical scores without leaving the guide.

Clinical safety

For trained clinicians. Not for diagnosis, dosing, or autonomous care. Resuscitation and local emergency pathways take priority.

Clinical assessment

Symptoms and validated scores determine low versus elevated clinical severity.

Symptoms attributable to acute PE?

Common symptoms are dyspnea and pleuritic chest pain; hemoptysis and syncope are less common. Tachypnea and hypoxemia may be present. Category A is reserved for incidentally diagnosed, asymptomatic PE.

Risk score calculators

Complete one or more. The score marked “Drives category” determines B versus C; the guideline does not define an automatic tie-break when completed scores disagree.
