## What is Critical ABG?

Critical ABG, from the creators of Critical-Medical Guide, is the first ABG app that is not only visually appealing but also provides a full analysis of acid-base disorders. We're all afraid of acid-base imbalances. Critical ABG will not only inform clinicians whether acid-base problems are present, but will also take you through a step-by-step approach to cognitively understanding the disorder, as well as common causes and differential treatment options based on the current literature. Critical ABG covers some of the most up-to-date differentials and treatments, as well as built-in compensation mechanisms, such as expected bicarbonate, pC02, Winter's formula, and more, - which everyone dreads having to memorize. 

Not only will the user learn about common disorders, but there's also a ventilation optimization calculator for those that need to adjust ventilator settings.

This app is not only suited for physicians, respiratory therapists, nurses, and PA's but also medical, nursing, PA, and paramedic students who wish to sharpen their acid-base interpretation skills. 

Remember always to treat the patient - not the numbers and to correlate clinically.  

Get Critical ABG now and enjoy the ease of interpretation. 

Critical ABG is based on common equations in the medical realm. The information included is solely for educational purposes and doesn't constitute medical advice. Therefore, always consult a physician before any diagnosis or treatment.

### 5/5 — BEST APP FOR ICU FOLKS

I use this app daily in the ICU. It’s straight to the point, easy to use, and in seconds tells you what to do for your patient and possible underlining causes. AMAZING.
