Pulmonology medical calculators
Respiratory severity and pneumonia scores.
Pulmonary calculators support A–a gradient interpretation, pneumonia severity with CURB-65, and related respiratory indices. FiO₂, ventilator settings, and underlying cardiopulmonary disease modify how these results should be applied.

A–a Oxygen Gradient
A–a GradientCalculate the alveolar–arterial oxygen gradient from ABG values and compare with age-expected normals.
CURB-65 Pneumonia Severity
CURB-65Stratify community-acquired pneumonia severity and site-of-care decisions using CURB-65.
PERC Rule for PE
PERCApply the PERC rule to help rule out pulmonary embolism in low-risk patients.
Wells Score for PE
Wells PEEstimate pretest probability of pulmonary embolism with the Wells PE criteria.
