VentRef vs PulmTools

VentRef is a focused clinical reference for clinicians managing invasive and noninvasive mechanical ventilation and oxygen therapy, grounded in core respiratory physiology and evidence-based critical care practice. This application is intended for educational and informational purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment. Calculations and reference values are derived from published peer-reviewed medical literature and textbooks cited in the Sources section of the app. Always seek the guidance of a qualified healthcare professional with any questions regarding medical conditions or clinical decisions, and do not disregard or delay seeking professional advice because of information provided by this app. About Rishi Kumar, MD, FACC ("RK.MD") I'm an adult cardiothoracic anesthesiologist and cardiovascular ICU intensivist practicing in academic medicine.

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. IMPORTANT INFORMATION PulmTools is intended for educational, informational, and clinical-reference purposes. It does not diagnose, recommend treatment, or replace professional medical judgment, institutional protocols, validated equipment measurements, or bedside assessment. Independently verify calculations, source inputs, and clinical decisions. Consult an appropriately qualified healthcare professional before making medical decisions. Do not enter patient names, medical record numbers, dates of birth, or other directly identifying information when saving cases.
