Well done on the highlighted emergency drug section on the front page.

Incredible, comprehensive resource for SRNA’s and CRNA’s alike.

I am an SRNA and utilize this app daily at clinical. It has helped me to feel more confident in room set and generally know what to expect with each case (especially as I am still learning). Additionally, their customer service and family-owned values make this such a worthwhile purchase: originally I bought this app on the Play Store but my phone broke less than a month after buying it. I was able to get in contact with them and they reimbursed my payment for the App Store after switching phones. Thanks for empowering SRNAs and helping so many learn about the amazing science of anesthesia!

Uses throughout school and clinical rotations. has been very reliable with up-to-date information from the most notable anesthesia textbooks

It has everything I needed for anesthesia school! In-depth adult & peds. case tips, weight based med tables, epidurals, regional blocks, all these apps combined into a huge app! I also like that the app contains input from various CRNAs and anesthesiologists that practice in specialized areas…so many resources. This is my go-to anesthesia app and I highly recommend this app to all anesthesia providers!

I bought this app several years ago as an anesthesia resident during Vargo’s annual sale and it was so worth every penny! I purchased several apps in preparation for anesthesia school, but the Vargo app was used everyday in preparation for clinical and when faced with unfamiliar cases. It is still the app I turn to as a nurse anesthesiologist.

Is missing a ton of different cases, and some of the cases it does have only have a couple sentences of information. Not a thorough or detailed app and definitely not worth 100$

Can we get an update with a tidal volume calculator??
rusny • Dec 1, 2022 ★ 5
My favorite anesthesia app. Would be great if you could add few more things such as:
1) regional/ blocks section
2) local anesthetic mixture max dose
3) ERAS protocols

Thank you for all your hard work

I’ve been using this app since I was a SRNA in 2016. It’s a must have as a student but I still find myself using it when I’m in cases I don’t do very often. I love the pediatrics dosages by weight when I’m in a pinch. The OB section and the calculations section are super helpful. It’s basically anything you need to know about anesthesia in the palm of your hand. I would rate higher than 5 stars if it would let me! Thanks Vargo!

This App is wonderful for both anesthesia residents and practicing anesthesia providers.

It has pertinent calculators, quick references for rarely used drugs, specific case tips, and refreshers for obstetric and cardiac anesthesia topics.

Worth the buy, especially for students.

I have been using this app since I was in anesthesia school. I graduated 2018 and still use it when I need clarification on dosages, procedures etc.. very helpful! I had an issue with the app matt responded in minutes and fixed the issue promptly. Highly Recommend!

There’s no other Anesthesia related app that compares. Regardless of being a SRNA, CRNA, AA, or Anesthesiologist; this app is the gold standard for utilization. Drug dosing and case set up have helped me enormously as a student and further prepared me once I was working independently. An absolute must have.

The app is great!! Worth every penny and should be on everyone’s phone in the field! Great resource with tons of updates often!!
ICU RN22 • Oct 6, 2022 ★ 5
Very easy to use. It is a great resource and I even used it as a bedside nurse to double check standard drug dosages when traveling to facilities that used different NMBs. It is quick and easy to access and has loads of information. They also recently added case tips which is awesome. Would recommend to any SRNA/CRNA and even bedside nurses who are travelers or switch types of units frequently who need to easily refresh on drug dosages and/or classes. It is a one time purchase. Some of the best money I have ever spent.

This app is like a gold mine for SRNAs. It is the best resource you will use as a student and probably for the rest of your career as a CRNA.

It has everything you could possibly want to look up whether that is to review information, learn new anesthesia stuff, or get insight on how you might want to perform a new case. All information included also has APA- cited references at the bottom, too.

The user interface is clean, neat, and organized. It has a search feature that is quick to display results, and it has tabs that allow for ease of finding what you want.

If you look at past reviews for anything less than 5 stars, it’s for things people want changed, updated, or improved. Each time, Vargo added the request in an update. For example, you can add your own notes which is extremely helpful. The app is frequently updated with new information or other features to make a continuously better experience for you. Plus, no additional monthly subscription fee and no data tracking. What more could you ask for?

Overall, it is an amazing little tool on your phone that you can take wherever you go. It’s something you will use in school and something you will use for the rest of your career, so it is 100% worth it. I would highly suggest this app for any SRNA!

This is an amazing app for any anesthesia provider. I have been using it for years, and it is very helpful.Furthermore, the customer service is excellent. I highly recommend this for any anesthesia provider.
Lee CRNA • Jul 1, 2022 ★ 5
This app has been great to have as a backup resource if there is a case I haven’t done in awhile and would like to review. Customer service has always been very prompt and helpful. Highly recommend!
SleeplessRN • Jun 10, 2022 ★ 5
This app is a necessity as an anesthesia professional. Really like how easy it is to use and covers almost every case I’ve tried to look up. They also have the greatest customer service I have ever dealt with! All around really amazing app, you won’t be disappointed!
