Inclusion criteria

• Diagnosis of pulmonary embolism according to clinical algorithm, confirmed by thoracic angioscan or ventilation perfusion (V/P) scan,
• Non-serious pulmonary embolism, not requiring intensive care (thrombectomy or fibrinolysis not considered).

• Patients with no contraindications to chair lift testing (no O2 at the time of testing).
• Effective anticoagulation for at least 1 hour.

Exclusion criteria

• sPESI score = 0 with outpatient referral.
• Diagnostic confirmation of Pulmonia Embolism by thoracic angioscan or scintigraphy more than 24h after suspicion of diagnosis.
• Hospitalization > 24h after introduction of anticoagulation, with subsequent confirmation by scintigraphy.
• Any sign of serious Pulmonia Embolism, requiring hospitalization in an intensive care unit.
• Asymptomatic Pulmonia Embolism discovered by chance
