Pedi-STAT is a rapid reference for RNs, paramedics, physicians and other healthcare professionals caring for pediatric patients in the emergency or critical care environment. ************************************ Reviews ************************************ Among "The Best Drug Reference Apps for Emergency Physicians" - Emergency Physicians Monthly 5 STARS - "Simple interface provides rapid access to critical data needed when managing a critically ill pediatric patient" 5 Stars - "Very useful for treating kids in high pressure situations with precision." ***************************** Pedi-STAT features include: - Rapid results for airway interventions including endotracheal tube sizes, depth, intubation medication dosages, ventilator settings, and sedation - Cardiac resuscitation data including weight specific dosages for resuscitation medications, cardioversion, and defibrillation - Access to age and weight specific pediatric equipment including foley catheters, airway management, chest and NG tubes, peripheral and central line sizes, and more - Seizure medication dosages - Management of hypoglycemia including age specific dextrose concentrations - Reference of age specific normal vital signs - Procedural sedation dosages including single dose meds and infusions, as well as reversal agents - Calculated pain management medications - Medical management of allergic reactions and anaphylaxis Users can quickly access critical information accurately, without having to rely on memory or cumbersome textbooks. With just a few taps, users have access to all the necessary data to care for a pediatric patient in the emergent setting, including weight-based and age specific medication dosages and equipment sizes. Since many of the patients present with minimal known information, all the results can be calculated rapidly with only a known age, date-of-birth, weight, length, or height. Simply enter the known variable and the data is instantly calculated. Developed by an Emergency Physician, this app minimizes the risk of medical errors allowing the provider to spend more time caring for the patient, and less time looking up and calculating doses. It is a critical companion for any physician, nurse, paramedic, or medical trainee involved in the care of critically ill pediatric patients.

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.

Verdict

The call

The clearest difference is price: ABG Expert at Free against Pedi STAT's $7.99. ABG Expert also leads on rating (4.8 vs 4.5) and review sentiment (100% vs 86%). Pedi STAT's advantage is update cadence (every 2 months vs every 5 months) and chart position (#2 vs unranked). On ads, in-app purchases and device support there is nothing between them.
