PFT & SPIROMETRY TOOL — EDUCATIONAL PATTERN REFERENCE FOR TRAINED CLINICIANS Built for pulmonary medicine residents, fellows, pulmonologists, and advanced medical learners who want a structured, guideline-aligned way to practice PFT pattern recognition—not a substitute for independent clinical judgment. Apply ERS/ATS interpretive strategies in one app: • ERS 2022+ interpretation (Z-score–forward, current ATS/ERS standard) • ERS pre-2022 interpretation (2005-era strategy for comparison and teaching) WHAT YOU CAN DO ▸ Discern physiologic patterns Enter spirometry, lung volumes, diffusion, and bronchodilator data. The app suggests obstructive, restrictive, mixed, and atypical patterns with severity grading—using transparent, guideline-based logic. ▸ Professional PDF outputs Generate clean, shareable PDF reports with findings, pattern summary, educational disclaimers, and a physician sign-off field—ideal for teaching conferences, case logs, and personal study records. Email directly from your device when Mail is configured. ▸ Dual-guideline learning Compare how the same data may be framed under current vs. prior ERS/ATS strategies—valuable for boards review, fellowship teaching, and understanding evolving standards. ▸ Educational differential reference (Premium) The Notes tab maps classic PFT patterns to commonly associated differential diagnoses (obstruction, restriction, mixed disorders, ILD, and more)—for manual study only. Pattern outputs do not auto-generate disease names; differentials are separated for educational clarity. ▸ Report library (Premium) Save, search, and re-export prior interpretations. De-identified labels only—do not enter patient identifiers. FREE VS PREMIUM Free: Disclaimers, regulatory information, subscription management, some content under Notes, and scroll preview of tools. Premium (7-day free trial, then auto-renewing subscription): • Full interpretation on both guideline tools • PDF generation and email send • Saved report history • Educational Notes & pattern-to-differential reference WHO THIS IS FOR Pulmonary & critical care fellows and residents Respirologists / pulmonologists refreshing pattern skills IM physicians with PFT interest Medical educators teaching spirometry interpretation NOT FOR patient self-diagnosis or unsupervised clinical decision-making.
