WHAT'S INSIDE

Six modules, fully built out.

Each module of Critical Care Vault is shaped around how that domain actually gets used at the bedside. Below is the full breakdown.

Hemodynamics

Hemodynamics, six ways to learn it.

The hemodynamics module is the deepest in the app, with six distinct learning modes — each shaped around a different way real ICU clinicians develop hemodynamic intuition.

Shock Profile No numbers — only directional arrows. Learn the hemodynamic signature of each shock family before you work with values.
Shock Recognition Read real ICU values. Name the shock. Broad family, then specific subtype.
Clinical Decisions You have the profile. Choose the intervention. Twelve options across fluids, pressors, inotropes, and more.
Recognize + Treat Two steps, one patient. Identify the shock first, then choose the intervention. The full clinical chain in one session.
Build Profile Mastery mode — given only the shock type name, reconstruct the entire hemodynamic profile from memory. All six parameters, no hints.
Simulate Choose an intervention; watch the parameters respond. Pure cause-and-effect physiology.
3 Step Escalation Capstone mode — one patient, three clinical turning points, the full deterioration arc from recognition to escalation.

EKG

EKG that teaches you to read, not memorize.

Anatomy → strips → lead-by-lead infarct localization. Each layer reinforces the previous one so rhythm reasoning becomes automatic instead of recalled.

Conduction Anatomy How the signal moves through the heart, mapped onto the surface EKG so you read with mental geography.
Rhythm Reference A clean, scrollable rhythm library — sinus tach to torsades, with the distinguishing features pulled out.
12-Lead Territory Lead-by-lead infarct localization: which artery feeds which territory, which leads cover which wall.
Test Yourself Self-graded practice with focused feedback on what you missed and why.

Question Bank

Hundreds of clinical questions. Every answer, explained.

The question bank spans cardiovascular, respiratory, neuro, renal, metabolic, and multisystem categories. Every question has a full rationale; correct AND incorrect choices get explanations. Spaced repetition surfaces what you missed.

Full Rationales Not just an answer key — a paragraph explaining the reasoning, often with a clinical pearl.
Category Tracking See your accuracy by category over time. Find the gap, then close it.
Spaced Repetition Missed questions return on the right day. Easy ones space out. The system optimizes your time.
Per-Session Shuffle Answer letters shuffle every session, so you actually learn the content — not the position.
Flag for Review Flag any question to come back to it later, separate from the spaced-repetition queue.
Advanced Practice Sets Curated sets covering CMC-tier topics: balloon pumps, ECMO, complex hemodynamic scenarios.

Drills

Six focused drills. Pattern recognition under mild pressure.

Drills are short sessions on a specific clinical domain. They run a little faster than the question bank, with tighter feedback loops — designed to build reflexes, not just knowledge.

Vasopressor Drill Match the shock state to the right pressor. Recognize when to add an inotrope. Recognize when fluids come first.
Vent Drill Mode selection, troubleshooting alarms, weaning, dyssynchrony recognition.
ABG Drill Acid-base interpretation under mild time pressure. Mixed disorders included.
Labs Drill Critical values, electrolyte derangements, what to act on now.
Fluid Drill Resuscitation, maintenance, replacement — when to pick which, and why.
Med Quiz Indication, dose, mechanism, key adverse effects. Ranked by clinical relevance.

Clinical Tools

Reference, calculators, protocols. One tap from home.

The tools section is built for the moments you need a reference between cases — not when you have time to crack open a textbook. Calculators do the math. Protocols stay close. Drug refs are organized by indication, not alphabetically.

Calculators MAP, CI, SVR, P/F ratio, anion gap, IBW (Devine), free water deficit, Fick CO. Educational implementations of standard published equations.
ICU Protocols Sepsis bundle, ARDS, post-cardiac arrest, DKA, withdrawal scales — organized by category and color-coded by domain.
Drug References Indication-first organization. What you reach for, not the alphabetical position.
Ventilator Modes Pressure vs volume, control modes, weaning modes, troubleshooting flowcharts.
Device Guides Pacers, IABP, CRRT — the basics you need before the conversation starts.

Progress

Your reasoning, tracked over time.

A live picture of how your clinical reasoning is improving. What you missed, what slowed you down, where you're strongest, what to study next. Optional cloud sync across devices.

Daily Activity Streaks and a calendar of which days you trained. No guilt-tripping — just visibility.
Category Accuracy Your accuracy in cardiovascular vs respiratory vs neuro etc., over time.
Spaced Repetition Queue A unified review queue across all modules — surfaces the right concept on the right day.
Session Log Every session you ran, when, with what score. Audit your own learning.
Cloud Sync (optional) Email + password account → progress syncs across devices. Or stay fully offline as a guest. Your call, no pressure.

Progress screen with streak count, daily activity, and category accuracy breakdowns.
