ABG Expert vs PulmTools

ABG Expert™ is simply the best acid-base analysis tool with features available in no other app. Designed and tested by practicing physicians, ABG Expert is trusted by medical professionals for unparalleled accuracy, flexibility, and power while remaining completely intuitive to use. Whether you are a physician, nurse, respiratory therapist, paramedic, or student, ABG Expert is your ideal acid base analysis app. Accuracy- • ABG Expert has been validated using extensive testing under real-world conditions. • No need to worry about entering physiologically impossible data by mistake. Data is checked for plausibility and for internal consistency using the Henderson-Hasselbalch equation. • An accurate analysis depends on an accurate anion gap. ABG Expert has you covered with automatic correction of the anion gap when albumin is provided. • Never again wonder about how a result was obtained. Detailed explanations include easy-to-understand equations so you can be sure the calculations are correct. Flexibility- • Need the arterial blood gas analysis, but not the anion gap or A-a gradient? No problem. ABG Expert can analyze the data for all three results separately or together. • Set the normal anion gap range based on the normal range at your institution. Or, use your patient’s own baseline anion gap to maximize your sensitivity to detect disorders. • Caring for an 80-year-old patient in Denver? Provide age and barometric pressure, and ABG Expert automatically adjusts interpretation of the A-a gradient. • Need more specificity? Adjust the normal delta gap range based on the literature you follow in your practice. • ABG Expert works as well in Bangkok as it does in Boston with full support for SI and non-SI units. Power- • Color-coded results allow for rapid analysis in critical situations. One additional click gives you a detailed differential diagnosis and additional recommendations. • Concerned about a new problem in your patient with advanced COPD? ABG Expert can adjust its calculations for chronic respiratory conditions so you can detect additional disorders that are missed by other apps. • Detailed explanations of disorders integrate ABG, anion gap, and A-a gradient results providing individualized answers like no textbook can. • Refine your differential diagnosis even further with the included osmolal gap and urine anion gap calculators. • ABG Expert combines beauty and brains with optimization for iOS devices running iOS 13 and later.

PulmTools is a focused respiratory and critical care toolkit for clinicians and learners. Interpret ABGs and VBGs, use clinical calculators and references, practice realistic cases, and follow learning or de-identified results over time. Start without registration. Core calculators and educational content are available in guest mode, while a free account enables synchronized progress and saved trends. INTERPRET ABGs & VBGs • Enter arterial or venous blood gas values through focused workflows. • Review pH status, likely primary patterns, expected compensation, and applicable oxygenation context. • See measured values alongside a structured interpretation. • Review methodology, limitations, and linked references within applicable tools. EXPLORE RESPIRATORY & CRITICAL CARE TOOLS Use focused calculators and references for: • Ventilator mechanics, minute ventilation, and static compliance • P/F ratio, A–a gradient, ROX index, oxygenation, and ARDS context • Fick cardiac output, hemodynamics, MAP, and shock index • Oxygen tank duration and respiratory support • Umbilical cord and capillary blood gases • Asthma and pulmonology references • Pulmonary risk and clinical-reference workflows • ECMO referral context and additional critical care tools LEARN THROUGH REALISTIC CASES • Build arterial blood gas interpretation skills with ABGenius. • Practice venous blood gas patterns with VBGenius. • Receive immediate feedback and clear explanations. • Use adaptive review and spaced repetition to revisit concepts that need more practice. • Follow accuracy, streaks, review readiness, and learning progress. SAVE & COMPARE TRENDS With a free account, you can: • Save calculator snapshots using non-identifying case aliases. • Compare measurements over time while retaining relevant clinical context. • Open focused trend analyses for supported tools. • Sync learning progress and saved trends across devices. RESET & REFOCUS Use PulmReset and guided Box Breathing for breathing practice and personal reflection between demanding moments. WHO PULMTOOLS IS FOR Designed for respiratory therapists, nurses, physicians, physician assistants, nurse practitioners, students, residents, fellows, and other respiratory and critical care learners.
