Mechanical Ventilation Expert vs ABG Calculator

Caution! This app is intended for intensive care physicians. If you are NOT a physician and would like to use it anyway, please consult your physician before using this app or making any medical decisions. This app has endorsement for usage in the Russian Federation. Many doctors deal with the treatment of patients with varying degrees of acute respiratory failure (ARF). But the choice of the optimal method and, especially, the timely correction of the parameters of invasive and non-invasive mechanical lung ventilation often cause difficulties, especially for young doctors. Unfortunately, expensive ventilation machines, without their skillful use, are not a guarantee of an improvement in the mortality rate in ARF. This has been especially evident during the COVID-19 pandemic. In international clinical practice, it is customary to determine the degree of ARF by the oxygenation index (the ratio of the partial pressure of oxygen in arterial blood (PaO2) to the fraction of inspired oxygen (FiO2)). This indicator is also included in most "severity of illness" scoring systems (SOFA, APACHE II-III, etc.). However PaO2 estimation is only possible after collecting the arterial blood for laboratory monitoring of blood gases, making it costly and invasive. In 2020-2021 a multicenter research was carried out at five clinical hospitals in Volgograd, Russia, which included 1038 patients with acute lung injury and acute respiratory distress syndrome against the background of viral (COVID-19) and bacterial pneumonia. The goals of the research were firstly, to develop a non-invasive method for determining the oxygenation index (PaO2 / FiO2) based on oxygen saturation (SpO2), and secondly, to define general criteria for correcting the parameters of invasive and non-invasive mechanical ventilation. This application is based on the results of the research. The relationship between SpO2 and PaO2 index values was determined for various FiO2 and types of respiratory support. The app also implements the general principle of oxygen therapy - from less to more invasive. The app allows the user not only to choose the most effective method of respiratory support, but also timely learn about the need for its correction. Every clinician knows that the mortality rate in patients with ARF is greatly influenced by the validity of the beginning and end of Invasive Mechanical Ventilation treatment - and this app solves this problem. The educational effect of this app should also be noted. It will help doctors to quickly master and more competently use expensive ventilation machines, which, of course, will have a beneficial effect on the results of treatment of patients with ARF.

Pulmoro is a clinical decision support app built for healthcare professionals managing patients with respiratory conditions, especially those requiring mechanical ventilation. It brings evidence based calculations, guided interpretations, and educational context into a single, intuitive platform designed for real time bedside care. Pulmoro was also selected as a 2025 Swift Student Challenge Winner, recognized by Apple for its creativity, technical skill, and meaningful impact in healthcare education. At the center of Pulmoro is arterial blood gas (ABG) interpretations with integrated oxygenation analysis. Clinicians receive immediate insight into acid-base status, compensation, and oxygenation, paired with concise explanations that connect physiology to practice. These interpretations are structured to deepen understanding, not just present simplified answers. Alongside ABG analysis, Pulmoro includes a comprehensive suite of respiratory and ventilator focused calculators. Users can quickly determine tidal volume, compliance, cardiac output, anion gap, the A-a gradient, and other essential values used daily in intensive care and emergency settings. Each calculator displays the underlying formula and reference ranges, allowing clinicians to see exactly how results are derived and reinforcing the physiology behind every number. Case studies woven throughout the app help users apply these calculations to realistic scenarios, bridging the gap between theory and bedside practice. Pulmoro functions as both a reference and a learning companion for clinicians strengthening their clinical reasoning skills. Pulmoro was created by a Respiratory Therapist with experience in intensive care, emergency medicine, and ECMO support. The app grew out of firsthand exposure to the complexities of respiratory care during the COVID-19 pandemic and beyond, inspiring a tool that simplifies critical decisions without sacrificing depth or accuracy. Accessibility and usability guided every design choice. Pulmoro adapts seamlessly to light and dark modes, emphasizes readable typography and contrast, and supports dynamic text sizing for varied clinical environments. It also functions fully offline, ensuring reliability in settings where connectivity may be limited. Pulmoro is not a replacement for clinical judgment, but a tool built to enhance it. By unifying ABG interpretation, oxygenation assessment, and essential ventilator calculations, it provides clinicians with a clear, reliable, and educational resource at the bedside. Whether used by respiratory therapists, physicians, nurses, or students, Pulmoro turns complex respiratory concepts into meaningful, actionable insights, helping clinicians deliver safer, more confident care.
