PE Classifier vs PFT Spirometry

PEClassifier is an educational reference tool designed to help medical students, residents, and clinical trainees learn and apply the 2026 AHA/ACC/ACCP/ACEP/CHEST acute pulmonary embolism classification system. LEARN THE FRAMEWORK The 2026 guideline introduced a comprehensive Category A–E classification system for acute PE severity. PEClassifier walks you through every category and sub-stage — B1/B2, C1–C3, D1–D2, and E1–E2 — with interactive diagrams that show how clinical criteria map to each classification. Understand not just the answer, but the reasoning behind it. Utilizes validated 11-item HESTIA checklist used to evaluate outpatient management eligibility — a key concept tested on boards and applied throughout clinical training. FEATURES - Full Category A–E classification with all sub-stages and R respiratory modifier - Interactive visual diagrams for every classification category - Built-in HESTIA checklist with all 11 validated criteria - Optional case log for self-study and review — saved locally on your device only, never transmitted anywhere - Direct link to the 2026 source guideline for reference and citation PRIVACY PEClassifier does not collect, transmit, or store any personally identifiable information. Any case log entries you save are stored locally on your device only, are entirely non-identifying, and are never shared with or sold to any third party. Uninstalling the app permanently removes all saved data. WHO IT'S FOR PEClassifier is intended for licensed healthcare professionals, medical students, and clinical trainees.

Make sense of pulmonary function tests—one pattern at a time. PFT Spirometry helps clinicians and medical learners practise PFT interpretation, compare the 2022 and 2005 ERS/ATS frameworks, and build clear reports for teaching and study. FROM VALUES TO A CLEAR PATTERN Enter spirometry, lung volumes, gas-transfer and bronchodilator measurements. Start with the pattern, then review relevant parameters, applicable severity grading and important gaps in the supplied data. Explore obstruction, restriction, mixed patterns and preserved-ratio abnormalities in one focused workspace. TWO FRAMEWORKS, ONE LEARNING TOOL Use PFTs 2022 for the 2022 interpretive framework or PFTs 2005 for the earlier strategy. Compare approaches while studying lung function, reviewing older reports or preparing for pulmonary medicine teaching and examinations. Enter the reference values supplied by the source laboratory. LESS TYPING WITH PHOTO IMPORT (BETA) Scan a report with the camera, choose a photo or open a PDF page. Native on-device recognition suggests values for review. Crop or rotate the table, compare suggestions with the source, correct entries and apply reviewed values before tapping Interpret. Recognition varies with image quality and layout; it may omit or misread values. Visual verification is required. REPORTS THAT KEEP THE DETAILS TOGETHER Create one-page PDF reports with raw values as entered, findings, the pattern summary, notes and educational limitations. Save, label, search and revisit reports for learning. Copy results or share a PDF using your device's sharing options. Use de-identified teaching cases. A SEARCHABLE PFT REFERENCE Open focused, collapsible Notes topics covering reference limits, spirometry quality, ventilatory patterns, bronchodilator response, lung volumes, DLCO, VA/KCO and interpretation pitfalls. Clinical context and differential considerations stay in Notes, separate from the tools' algorithmic pattern output. Follow linked primary references for further reading. MADE FOR FOCUSED STUDY A compact interface, optional slider inputs and adjustable text size help you work at your preferred pace on iPhone or iPad. Interpretation and report storage run locally; no app account is required. Imported images are not attached to saved reports or uploaded to a developer-operated recognition service. FREE AND PREMIUM Free access includes most Notes topics, reading preferences, educational-use information and previews of the tools. PFT Premium unlocks both interpretation tools, photo import (Beta), PDF export, saved report history and all Notes topics. Monthly and yearly auto-renewing plans are available. Prices and any eligible introductory trial are shown before purchase. EDUCATIONAL USE For qualified healthcare professionals and medical learners under appropriate supervision. Outputs are algorithmic educational pattern suggestions, not diagnoses or treatment advice. They may be incomplete or incorrect and require independent verification by a qualified clinician against the original report, test quality, clinical context and applicable standards. Not for patient self-diagnosis or use as the sole basis for clinical decisions. SUBSCRIPTIONS Payment is charged to your Apple Account.
