## Critical 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

### ***** "International fixed wing medevac and Critical"
Easily and hands gown the best app to have at hand. I use this app on every trip whether to calculate O2 cylinder times or to pre calculate RSI doses in the event they may be needed. There is a lot to be said for removing cognitive load on the provider, specifically in emergency situations. The fact that the app is not dependent upon WiFi availability makes it my first go to for a ton of out of hospital uses
-- Jed Deep, 2024-05-01

### ****- "Can’t edit med doses"
Great app, but can’t edit med doses to reflect my specific protocols
-- jetman, 2024-04-14

### ***-- "Was great.  Drip function calculator stopped working"
Hoping to get the devs attention, the drip rate and other tools have stopped working.  Otherwise a 5 star product.
-- Vantastic skadoosh, 2023-12-15

### *---- "Review"
Not worth the money. Very little information in app.
-- Smhq4882, 2023-12-06

### ***** "My go to app"
This is tge one tge  I use 99% of the time.
-- Jdgito253, 2023-08-26

### ***** "Great app for flights clinicians/critical care"
This app is excellent!! I use it as a flight nurse and it gives me everything I need as a quick reference. I love the clinical calculators and pediatric reference as well. The design is easy to use, aesthetically pleasing, and works without Wi-Fi.
-- Heavenly072, 2023-08-14

### ***** "LOVE IT!"
I’ve been using the app forever and it gets better all the time. I recommend it to everyone and wish it was shown to me many years ago! Started using it the heaviest when I first started working as a flight paramedic. Saved my bacon more than once.

Single elements of Critical are done better than apps that revolve around just 1 of the dozens of things it can be used for. 

Keep making it great! Thanks for all you do.
-- Alejandrones, 2023-05-20

### ***** "Great CCRN, CFRN, CCP, & FPC"
This app is easy to use. Company puts out updates & backed by a critical care team.
-- Keith's iPhone 2022, 2023-05-18

### ***** "Critical"
Use this app routinely in flight and on the rig. Great app to use in conjunction with our protocols!
-- Jessop Bawek, 2023-04-26

### ***** "I don’t write reviews, get this app!"
This is HANDS DOWN the best app for emergency medicine. 911 EMS, or critical care transport.
-- Dgray251, 2023-02-26
