ICU Advantage Rapid Reference
The critical care reference
Free · In-App Purchases · Designed for iPad
ICU Advantage: Rapid Reference is the clinical reference and resource for those caring for critically ill patients. Built to help you understand the complexity of critical care, not just look things up and forgetting.
From the team behind the ICU Advantage YouTube channel, trusted by more than 950,000 nurses and critical care professionals worldwide.
FOR THE WHOLE CRITICAL CARE TEAM
Nurses, respiratory therapists, pharmacists, residents, advanced practice providers, and anyone who takes care of critically ill patients.

BUILT TO HELP YOU UNDERSTAND, NOT JUST LOOK UP
Every topic is written to actually teach, not just summarize. Same philosophy as the ICU Advantage YouTube channel: take something genuinely complex, break it down into pieces that make sense, and leave you knowing the "why," not just the "what." When you need a quick review or refresher, the Rapid Reference for each content area surfaces the important, high-value information for quick access, with links to dive deeper into the parts you need.
DESIGNED FOR CLINICIANS
Clean, readable, and beautifully rendered. This doesn't just feel like reading a textbook on your phone. Elegantly designed to look great and stay readable in dark mode or light mode, on iPhone and iPad. Works fully offline, so it is there when the network is not. Bookmarks and favorites for the topics you come back to. No ads, no social feed, no distractions. Just the information you need, organized for quick access and the way you think.
HONEST ABOUT WHAT THIS IS
Rapid Reference is a reference and education tool. It is not medical advice, not a diagnostic device, and not a replacement for your institution's policies, procedures, the laws and regulations of your licensing governing body, or the orders of a qualified prescribing provider. Always defer to your local protocols and clinical judgment.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
This is the first update since launch and it's a big one! Built around what you all asked for!
THE BIG ONE!! By far the most requested and YES reference images for the clinical content are on the way!
- This update lays the groundwork for reference images in your content. The app is now ready to display them, and the images themselves will begin arriving through in-app content library updates. The first ones right after the update goes live. No app update needed as more images get added.
Units, your way
- A new early stage all-in-one Unit Converter in Calculators: Quickly convert from one unit to another. Tap swap to flip the direction.
- Set your lab values to US (mg/dL) or SI (mmol/L) and your measurements to metric or US once in Settings. Calculators are the first place this goes live, with more of the app to follow.
- Calculators now accept comma decimals too, so an entry like "0,5" works.
Want to see one of the in-app messages again?
- The new Notification History lets you reopen any in-app message you received, even one you dismissed too fast.
Smoother and more reliable
- You stay signed in until you choose to sign out.
- Faster startup, with no more unnecessary "building search index" loading.
- Your library downloads are more reliable across different networks.
- An expanded lab panel Info card now scrolls instead of cutting off on smaller screens.
- The in-app How It Works guide is fully refreshed with the latest changes.
- Many more little bug and content fixes that you guys found and pointed out to me!
