ABG Expert vs VentilO

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.

The VentilO application is a mobile educational application that allows healthcare professionals in charge of patients with mechanical ventilation: (i) to learn how to set the initial ventilatory settings in volume-controlled ventilation mode based on several parameters, (ii) to reason about the influence of different parameters on ventilatory needs in adult patients, (iii) to learn about optimization of ventilator settings for oxygenation, lung protection and CO2 elimination (iv) to learn about the impact of dead space on ventilation efficiency. The initial settings for minute ventilation (tidal volume (VT) and respiratory rate (RR)) will be proposed. The VT will be determined according to the predicted body weight, the body temperature and the type of patient (medical or surgical). VT/RR combinations for different targets of VT (3 to 10 mL / kg PBW will be provided, settings from 6 to 8 mL/kg PBW will be preferred). Educational texts are proposed to help other settings (PEEP and FiO2) in the different care contexts. ‘’Optimizing settings’’ is covered in another separate tab. Will provide calculation of several parameters (alveolar ventilation, dead space…) based on the patient’s data, ventilator settings and arterial blood gases results. In addition interpretations will be provided for Oxygenation, Ventilation (CO2) and Lung protection. In another separate tab ‘’Tools&Calculators’’, several tools are provided: -Impact of the instrumental is explained in details. Minute ventilation and alveolar ventilation (minute ventilation - dead space ventilation) are calculated. The physiological dead space is calculated according to published formulas linked to the predicted body weight of the patients, the instrumental dead space (linked to the volumes of the endotracheal tubes, connections, heat and moisture exchangers) is calculated. The impact of reducing dead space on several parameters is calculated (gain in alveolar ventilation, gain in reduction in tidal volume (and associated reduction in plateau pressure),or respiratory rate with constant alveolar ventilation) - Different Calculators (P/F ratio from SpO2, PBW…) -Links to several additional tools (Quick Reference Respiratory Care Card; O2 demand calculator, Recruitment to Inflation Ratio…) In addition to the measurements of these different parameters, several educational texts are accessible in the application to understand what dead space is during mechanical ventilation, what is instrumental dead space, what is the impact of dead space in function of ventilation settings and possible gains. These calculations and descriptions concern ventilated adult patients, in the emergency room, intensive care units and in the operating room. The VentilO application was developed with the help of several mechanical ventilation experts. The mobile application is trilingual (English, French and Spanish), based on the users settings.
