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.

Features
Read full description

"Hypernatremia Correction Rate: Sodium Tracker" app is designed to treat hypernatremia. Hypernatremia is a condition that occurs when serum sodium level is high (>145 mmol/L). Elevated sodium level is often caused by dehydration. Acute symptomatic hypernatremia should be corrected rapidly while chronic hypernatremia should be corrected more slowly. Why should you choose "Hypernatremia Correction Rate: Sodium Tracker"? - Simple and very easy to use. - Precise calculation with Adrogue formula. - Selection of most used fluids in treating hypernatremia. - Correction rate can be adjusted based on clinical judgment. - The result is showing the amount of selected fluids per hour. - The result is also showing infusion rate of selected fluids in drops per minute. - It is totally free. Download now! "Hypernatremia Correction Rate: Sodium Tracker" app will help doctor to adjust the correction rate to avoid over or under correction of the sodium level. Rapid sodium correction could cause cerebral edema. The calculation in this application is based on Adrogue formula. In "Hypernatremia Correction Rate: Sodium Tracker" app, the result of the calculation will be shown in the amount of selected fluids per hour. This application is also showing infusion rate of selected fluid with drops factors of 20 drops/ml and 15 drops/ml. Therefore, the calculation result is also applicable in a hospital without infusion pump. Correction rate also can be adjusted manually based on clinical judgment. Disclaimer: all calculations must be re-checked and should not be used alone to guide patient care, nor should they substitute for clinical judgment.
