VentRef vs Critical Care Vault

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.

Critical care rewards the clinician who can reason fast: read the numbers, see the pattern, choose the next move. Critical Care Vault is built to train that, not just test recall. It pairs interactive reasoning practice with a bedside reference so you can sharpen your thinking on a slow afternoon and look something up between cases on a busy one. Built from bedside critical-care experience for the whole ICU team: nurses, NPs, PAs, residents, fellows, RTs, pharmacists finding their footing, and intensivists keeping pattern recognition sharp. Guest mode includes a limited preview of selected tools and training content. Create a free account to unlock the full app. No ads. No subscription. TRAIN THE REASONING • Question Bank — 850+ clinical questions across cardiac, pulmonary, neuro, renal, hematology/immunology, endocrine/metabolic, GI, multisystem, professional/ethical, and device topics, written to mirror real ICU decision points. Every question is cited; newer sets break down why the right answer is right, why each wrong one is wrong, and the pearl that ties it together. Spaced review brings back what you miss. • Bedside Simulation — Run a simulated ICU case on a monitor, ventilator, pacer, or Swan: make a call, watch the modeled physiology respond, then debrief what actually helped. Shock, low-flow states, bradycardia and pacing, and ventilator management. • Hemodynamics Trainer — Six progressive modes that turn pressure, volume, and resistance into reflex-level pattern recognition. Read the shock state from the profile, predict the response to an intervention, and work a deteriorating case step by step. • EKG Trainer — Conduction anatomy, 12-lead territory mapping, a clean rhythm library, and timed self-assessment. Sinus tach through VT, AV blocks, axis, and lead-by-lead infarct localization. • Study Modules — One ICU topic at a time, concepts first, then check yourself: Vasopressors, Ventilator, ABG, Labs, Fluids, Hemodynamics, and Pharmacology. Progress is tracked on each. KEEP THE REFERENCE CLOSE • Clinical Tools — ICU calculators and scores, including MAP, CI, SVR, P/F ratio, anion gap, IBW, free water deficit, Fick CO, drip rate, and more. • Protocols & Device Guides — Quick-access reference for shock, sepsis, ARDS, neuro, and surgical care, plus equipment-focused guides for ventilators, oxygen devices, pacers, PA waveforms, and CRRT. • Medications — A dedicated ICU drug reference with case-based scenarios that put pharmacology into real decisions. • Unified Search — One bar across questions, glossary, abbreviations, medications, and reference cards. Guest search respects preview limits; account mode unlocks full search coverage. BUILT FOR THE UNIT • Offline-first — bundled content available to your current access level works offline after setup. • Optional cloud sync — carry your history and progress across devices. • Dark, monitor-style interface with a light mode for shared screens. • No ads, no subscription, and no advertising tracking. INTENDED USE Critical Care Vault is an educational training and reference tool for trained healthcare professionals. It is not a medical device, does not provide patient-specific diagnostic or treatment recommendations, and is not a substitute for clinical judgment, institutional protocols, or provider orders.
