Tired of subscriptions? After testing Acid Plus for free, you can now *unlock Acid Plus for life* with a one-time purchase.
Designed, programmed, and used by two internal medicine docs, Acid Plus is an essential tool for healthcare professionals who need quick, detailed, and easy-to-interpret acid-base results from ABGs and metabolic panels.
Ideal for MDs, PAs, NPs, RNs, RTs, EMTs, and med students, everything you need for acid-base calculations is put right in the palm of your hand. No more clunky ABG websites or guesswork.
With an intuitive design and easy-to-read display, Acid Plus makes it a breeze to answer even the most complex acid-base problems in seconds. Just turn the device to landscape view to get a colorful graph with an arrow highlighting the disorder.
*** What Others Say **************

I’ve been missing this for a while but all the extra details available and being able to set the graph manually are really useful. Great update, thanks!
So useful

Not only is it easy to use but there’s just so much detailed info available. Really helpful to be able to see how all the results are derived.
Love this ABG app

The perfect app for the wards. The picker for choosing values is great.
Fast, accurate, and useful

I'm a medical student who is going through the core medicine rotatation. I have used this app several times to analyze ABG's and it does the job quite well. You can recall previous entries with the refresh button. The graph mode that shows you were you are on the blood gas spectrum is also very helpful. A venous blood gas analysis mode (limited as it is) would also be helpful. It would also be helpful if it was possible to more explicity save prior ABG analyses. I have compared the results from Acid Plus with the results from the Mediquations Acid-Base compensation. The two are consistent but at times when the ABG are somewhat off (due to analyzer issues, etc.) or otherwise ambiguous, Mediquations provides alternative interpretations, which Acid Plus does not. However, Acid Plus has been reasonable and presented the most likely interpretation which has been consistent with clinical observations in cases that I have checked. One area of possible inaccuracy could occur in cases where the albumin is very low. From Rennke and Denker (2007), in hypoalbuminemia, the normal anion gap value must be adjusted downward. "The approximate correction factor is a reduction in the anion gap of 1.5 mEq/L for every 1.0-g/dL reduction {from 4.0 to 4.5} in the plasma albumin concentration ...." Thus, low albumin can change the interpretation of anion gap. This application does not consider this.
Thank you for using Acid Plus!
