Wells Score Calculator

Calculate the Wells Score to estimate probability of Pulmonary Embolism (PE) or Deep Vein Thrombosis (DVT).

📋

Input Parameters

Enter details for calculation.

Wells Score

0
PE Unlikely
💡

Expert Tip

A Wells score ≤ 4 indicates PE is unlikely. Combine with a negative D-dimer test to safely rule out PE without CT imaging.

Calculation Methodology & Details

📐

Formula

Score = Sum of active clinical findings (max 12.5)

Points assigned based on clinical signs, history, and heart rate parameters.

FAQ

How is Mean Arterial Pressure (MAP) calculated?
MAP reflects average arterial pressure during a cardiac cycle. It is calculated as DP + 1/3(SP - DP), where DP is diastolic pressure and SP is systolic pressure.
What is the clinical significance of a prolonged QTc interval?
A QTc interval above 450 ms in men or 460 ms in women increases the risk of ventricular arrhythmias, specifically Torsades de Pointes.
Can risk scores replace acute clinical evaluation?
No. Risk calculators like HEART, TIMI, or GRACE assist emergency clinicians, but should never replace clinical judgment or urgent medical intervention in acute coronary syndromes.
