I always had to do all of my calculations in my head, or on paper. The process took about ten minutes to confirm all of my calculations. I still double check my calculations with this app, and it is perfect every time. When seconds count in Emergency and Critical Care Medicine; This is the App you need! DasBÖHLER Critical Care/Flight Paramedic ### 1/5 — No longer up to date *2026-07-11, version 33* I used to love this app but it is no longer current with aha guidelines (2015 ACLS) nor medical standards of care. A waste of money. 😢 ### 5/5 — CC Paramedic lifesaver!!!!!! *2026-05-30, version 33* This is one of my fast reference’s for the field! It’s become my workhorse when things get hairy and I need offline info NOW! ### 3/5 — No support *2026-05-12, version 33* App is great, but it is missing the built in conversion factor to calculate Os on the EC135 single or double tank set up. There hasn’t been an update for 3 years, and the website for the dev is no good. ### 5/5 — What I need *2026-02-25, version 33* I love this app! It’s so helpful in the little rural critical access hospital I work at where the nurse is also RT, pharmacist, and lab. Can it be updated to reflect 2025 ACLS guidelines? ### 1/5 — Not great *2026-01-19, version 33* I wouldn’t download this for free! Had so many good reviews I gave it a shot. It’s terrible. I’m incredibly frustrated that I wasted my money. You have many resources at your place off employment that far exceed what is available on this app. Don’t bother. ### 5/5 — Great resource *2025-06-17, version 33* Love this app for quick access to pertinent information at my fingertips ### 5/5 — I don’t write reviews, get this app! *2025-03-10, version 33* This is HANDS DOWN the best app for emergency medicine. 911 EMS, or critical care transport. Seriously, I recommend this app to ALL of my colleagues every chance I get. This is such a necessary pocket tool to take to the field. ### 4/5 — Only one thing missing *2025-01-21, version 33* I love this app and I’ve been using it for years, both in the ER and on the ambulance. The only thing I wish it had was the ability to put in the ranges for drugs for my protocols so I could just put in the patients weight and see exactly what I need to draw up for IVP meds. ### 5/5 — Awesome! *2025-01-09, version 33* Everything at your fingertips! Great app and worth the price. ## Frequently asked questions about Critical ### What is Critical- Medical Guide?
