PESI (Pulmonary Embolism Severity Index) from Aujesky 2005

PESI (Pulmonary Embolism Severity Index) from Aujesky 2005: age in years plus male sex (+10), cancer (+30), heart failure (+10), chronic lung disease (+10), heart rate >=110 (+20), SBP <100 mm Hg (+30), respiratory rate >=30 (+20), temperature <36 C (+20), altered mental status (+60), and SpO2 <90% (+20). Classes I (<=65) through V (>125). Only for already diagnosed PE. Not a diagnosis, not an outpatient protocol, not sPESI, and not the 17-variable laboratory model.
