Pulmonary Embolism Severity Index (PESI)
Cardiology
Also known as: Pulmoner Emboli Ciddiyet İndeksi (PESI)
What it is for
Pulmonary Embolism Severity Index (PESI): prognostic score for patients with acute pulmonary embolism, built on 11 clinical variables and estimating 30-day mortality risk. The total is the age in years plus the points for each finding present:

| Chronic lung disease | +10 |
| Heart rate 110/min or more | +20 |
| Systolic blood pressure <100 mmHg | +30 |
| Respiratory rate 30/min or more | +20 |
| Temperature <36 °C | +20 |
| Altered mental status (disorientation, lethargy, stupor or coma) | +60 |
| Arterial oxygen saturation <90% | +20 |
| Risk classes | class I ≤65 points (very low risk); class II 66-85 (low); class III 86-105 (intermediate); class IV 106-125 (high); class V >125 (very high). |
