PulmTools
Evidence-informed tools and calm, practical learning for respiratory care professionals.
Quick Analyzers
Analyze a real blood gas fast
Already have values from the ICU, ED, or class? Jump straight into the ABG or VBG analyzer instead of practice mode.
ABG Analyzer
Enter pH, PaCO₂, HCO₃⁻, and PaO₂ to review acid-base status, compensation, and oxygenation classification.
VBG Analyzer
Enter pH, PvCO₂, and HCO₃⁻ to quickly interpret venous acid-base status and compensation patterns.
Available Tools
Explore PulmTools by clinical workflow: acid–base, oxygenation, ventilation, and perfusion.
Core Calculators · Acid–Base
ABGenius
Interpret the provided ABG values (pH, PaCO₂, HCO₃⁻, PaO₂) to determine the correct acid-base disorder, compensation status, and oxygenation category.
VBGenius
Practice venous blood gas interpretation using pH, PvCO₂, and HCO₃⁻ to identify acid-base disorders and compensation without oxygenation analysis.
Winters' Formula
Estimate the expected PaCO₂ in metabolic acidosis using Winter’s formula to assess respiratory compensation.
Respiratory Compensation Calculator
Estimate expected HCO₃⁻ changes in acute and chronic respiratory acidosis or alkalosis and compare measured bicarbonate to expected compensation.
Anion Gap Calculator
Calculate anion gap, corrected anion gap, and delta ratio to evaluate metabolic acidosis and mixed acid-base disorders.
Delta Gap Calculator
Compare changes in anion gap and bicarbonate to help detect mixed metabolic acid-base disorders in high anion gap acidosis.
Oxygenation & Respiratory Failure
P/F Ratio – OI Guidance
Assess oxygenation efficiency using P/F ratio and Oxygenation Index to guide escalation of respiratory support.
A–a Gradient Calculator
Estimate alveolar-arterial oxygen gradient to evaluate causes of hypoxemia and guide differential diagnosis.
ROX Index Calculator
Calculate the ROX index using SpO₂, FiO₂, and respiratory rate to help assess HFNC response and escalation risk.
Breathwork Hub
Guided coherence, box, and 4–7–8 breathing with timing cues, physiology explainers, and benefits for clinicians and patients.
