ABG Acid vs ABG Expert

ABG Acid-Base eval walks a clinician through a stepwise approach to analyse ABG's and electrolytes in order to arrive at acid-base disorders and diagnostic ideas about ill patients. It is based mainly upon a worksheet developed by Dr. Erik Rupard from the medical literature. This tool not only yields answers, but just as importantly teaches the stepwise thinking process and the necessary concepts along the way. A clinician or learner will wind up with good information that assists patient care and should wind up a little smarter and more able to do it with less assistance the next time. It is a great support for those of us clinicians who use these tests only occasionally and don't have it memorized. The differential diagnoses include the classic mnemonics like MUDPILERS, CHAMPS, CLEVER PD, and HARDUPS, with explanations and examples. The app addresses such common questions as: * What are common causes of metabolic acidosis? respiratory alkalosis? * How do I calculate predicted pCO2? corrected bicarbonate? * What is the primary acid-base disorder? * Are additional acid-base disorders present, and if so, what are they? This app is written and intended for practicing clinicians like internists, family physicians, ER docs, cardiologists, pulmonologists, intensivists, and hospitalists; for resident physician trainees; for medical students; and of course for other clinician colleagues like NP's and PA's. As an educator and clinician, I am interested in feedback and I would be grateful for guidance on improving the tool. Notes of importance: - many thresholds and cutoffs are arbitrary and debatable, so you will have to use judgment to interpret which disorders are present and to what extent when suggested by the app - the app facilitates you to evaluate the data. If you make a mistake, the app will not argue with you. It will, at the end, offer to compare your work to the disorders that the app finds using the same algorithm - patients are more than the sums of their numbers and data, and they are often unique individuals. Use this information as a starting point in the evaluation of your patient and always do your own thinking!

ABG Expert™ is simply the best acid-base analysis tool with features available in no other app. Designed and tested by practicing physicians, ABG Expert is trusted by medical professionals for unparalleled accuracy, flexibility, and power while remaining completely intuitive to use. Whether you are a physician, nurse, respiratory therapist, paramedic, or student, ABG Expert is your ideal acid base analysis app. Accuracy- • ABG Expert has been validated using extensive testing under real-world conditions. • No need to worry about entering physiologically impossible data by mistake. Data is checked for plausibility and for internal consistency using the Henderson-Hasselbalch equation. • An accurate analysis depends on an accurate anion gap. ABG Expert has you covered with automatic correction of the anion gap when albumin is provided. • Never again wonder about how a result was obtained. Detailed explanations include easy-to-understand equations so you can be sure the calculations are correct. Flexibility- • Need the arterial blood gas analysis, but not the anion gap or A-a gradient? No problem. ABG Expert can analyze the data for all three results separately or together. • Set the normal anion gap range based on the normal range at your institution. Or, use your patient’s own baseline anion gap to maximize your sensitivity to detect disorders. • Caring for an 80-year-old patient in Denver? Provide age and barometric pressure, and ABG Expert automatically adjusts interpretation of the A-a gradient. • Need more specificity? Adjust the normal delta gap range based on the literature you follow in your practice. • ABG Expert works as well in Bangkok as it does in Boston with full support for SI and non-SI units. Power- • Color-coded results allow for rapid analysis in critical situations. One additional click gives you a detailed differential diagnosis and additional recommendations. • Concerned about a new problem in your patient with advanced COPD? ABG Expert can adjust its calculations for chronic respiratory conditions so you can detect additional disorders that are missed by other apps. • Detailed explanations of disorders integrate ABG, anion gap, and A-a gradient results providing individualized answers like no textbook can. • Refine your differential diagnosis even further with the included osmolal gap and urine anion gap calculators. • ABG Expert combines beauty and brains with optimization for iOS devices running iOS 13 and later.
