## Critical Med Description
Critical Med is a fast, fully offline study companion and reference for critical care clinicians — nurses, paramedics, residents, and attendings. It opens in one tap with no account and no sign-in, so your study material is always ready.

ACLS & RECERTIFICATION STUDY
- Over 800 clinician-reviewed practice questions with the reasoning behind each answer
- Timed 50-question practice exams scored against the 84% pass line
- 11 megacode practice scenarios, each with a review debrief
- Adaptive review that resurfaces the topics you keep missing

STUDY LIBRARY & REFERENCE
- Reference notes on meds commonly seen in critical care
- Over 500 IV compatibility reference pairs
- ICU infusion reference entries
- Lab value references with typical ranges and study notes

RHYTHMS & MONITORING STUDY
- 30 rhythms in an interactive practice simulator to build recognition
- Study guides for CBC, CMP, coagulation, and acid-base concepts
- Reference material on ventilation, capnography, hemodynamics, pacemakers, and ECMO

PROCEDURE & SCENARIO STUDY
- Illustrated procedure study guides
- 100 clinical study playbooks for less common scenarios
- Pediatric and obstetric study references

STUDY ANYWHERE, EVEN OFFLINE
Everything works offline with no account or sign-in, plus a fresh study brief every morning.

Important: Critical Med is an educational study and reference tool. It does not provide diagnosis, treatment directives, or emergency services, and it is not a substitute for professional clinical judgment or facility protocols. ACLS study content supports personal exam preparation only; it is not AHA-accredited and does not grant a certification card.

## Critical Med Reviews in United States

### ****- "Venous Blood Gas PLEASE"
This is a great app that was introduced to me when I started flying as a flight paramedic. My only complaint is that there is a ABG calculator that is extremely useful but no VBG calculator. Our point of care labs are most commonly VBGs from an IV line so can there please be a VBG calculator added? This is the only reason I’m giving it 4 stars instead of 5.
-- Ramburn, 2024-12-27

### ***** "Most helpful app"
This is by far the best app out there to have. I’ve recommended it to A lot of people
-- Rowshambow, 2024-12-15

### ***** "Best App"
Over the years I've been through a lot of medical apps. I've now had this app for years, and it is my go to app. Over the past almost 3 decades I've been an ICU and ER nurse, currently full time flight nurse/medic for the past 13 yrs. I have gifted and recommend this app many times. Cannot recommend this app enough.
-- nonicnameavailable, 2024-11-20

### ***** "Foundational app for critical care transport"
I love this app for pharm reference on the go, the pediatric section, vent optimization. Just so many useful sections on it. 

I would add an IV drug compatability checker.
-- Goodlordt, 2024-10-08

### ***** "The best HCP app"
Excellent
-- Benyi2782, 2024-09-30

### ***-- "No updates in 2 years"
See above.
-- R. Layne, 2024-09-23

### ***** "Fantastic Reference Tool"
My only complaint is that I didn’t come across it sooner. 

Ultrasound updates?
-- syoung236, 2024-08-16

### ***** "Outstanding"
I just got this. I wish I had access to this when I was working, retired RN( active license) still like many, love to keep current. Having done so much in a long career ( like my wife) I was a Nurse before men were in the field. This has pharmacy information ( was at UConn in pharmacy school) before I dropped my 1-A, with a low draft number. Medic, changed after to Nursing with my wife. This has a wealth of information. OB-GYN( first male RN) early, decelerations) Point is I’ve never seen so much in one spot except PDR, or Taber’s.
-- Aircavmedic, 2024-07-12

### ***** "Chief of EMS"
A must have App for any paramedic or critical care service.
-- Teton Jack, 2024-07-11

### *---- "Was great now doesn’t work"
This was a great app I showed all of my students. Any more the drip section no longer calculates the mL/hr. No matter what I put in it doesn’t do the calculations. I hope this is fixed.
-- Harrison Palmer, 2024-07-08
