Pulmonary Embolism Severity Index (PESI) -- Full Version

Full PESI score predicts 30-day mortality in acute pulmonary embolism. Classifies patients into 5 risk classes (I-V) based on age, sex, cancer, heart failure, COPD, heart rate, systolic BP, respiratory rate, temperature, mental status, and O2 saturation. Risk Class I-II (very low/low) may be suitable for outpatient treatment with DOAC. Validated in 11,000+ patients. Note: simplified PESI (sPESI) also available in this app.

Patient age (years) -- age is added directly to the score*(years)

Sex*

Cancer (history of or active cancer)*

Heart failure (known chronic heart failure)*

Chronic lung disease (COPD, asthma, pulmonary fibrosis)*

Heart rate above 110 bpm*

Systolic blood pressure below 100 mmHg*

Respiratory rate at or above 30/min*

Temperature below 36 degrees Celsius*

Altered mental status (disorientation, lethargy, stupor, or coma)*

SpO2 below 90% on room air*
