Respiratory Study Buddy is a study companion for respiratory therapy students preparing for board exams. It is built around one idea: you learn respiratory therapy by working through it, not by rereading it. Every flashcard carries the reasoning on the back, every quiz question explains why the wrong answers are wrong, and the simulators let you change one thing and watch what happens. WHAT IS INSIDE 1,030 flashcards across 13 decks Patient assessment, airway management, oxygen therapy, mechanical ventilation, pharmacology, blood gases, imaging, pulmonary function, infection control, pathology, equipment, neonatal and pediatrics, and calculations. Every card carries an explanation, a registry tip and a clinical pearl. Quiz Yourself Multiple choice drawn from the card bank, plus 28 authored patient scenario questions and 42 select-all-that-apply items. Nothing is revealed until you check your answer, you can skip a question and come back to it, and anything you miss is queued for review. Full-length mock exam 185 questions in one timed sitting: 100 recall items, 60 clinical judgment items and 25 unscored pretest questions, reported by domain rather than as a single score. CSE Practice Nine branching clinical simulation cases where what you choose changes what happens next. ABG Practice Interpret gases, sharpen the calculations, and check your reasoning against a worked explanation. Vent Lab A ventilator simulator with a free practice sandbox and nine patient cases, from COPD and severe asthma to ARDS, chest trauma, a child in status asthmaticus and a premature newborn. Change a setting and watch the waveforms, pressures and gas exchange respond, then ask for feedback when you are ready. Reference worth keeping RT Notes across ten illustrated categories, 28 chest X-rays with described findings, lung sound recordings, 100 vocabulary terms, 25 board buzzwords, and 22 study tool pages covering test strategy, formulas, normal values and mnemonics. Study calendar and spaced repetition Add your exams, check-offs and clinical dates. Cards you have seen come back on a schedule, and the ones you missed come back sooner. Question of the Day widget One question on your home screen, new every day. FOR EDUCATION, NOT CLINICAL PRACTICE This app is a study aid. It is not medical advice, it does not provide diagnosis or treatment recommendations, and nothing in it should be used to guide the care of an actual patient. It is not intended for use during medical emergencies or as a clinical decision support system. Real clinical decisions follow your institution's protocols and the judgment of licensed clinicians. Respiratory Study Buddy is an independent educational application. It is not affiliated with, endorsed by or sponsored by the National Board for Respiratory Care or any other credentialing body. TRY IT FIRST Free to download with a sampler across every deck, and one purchase unlocks the whole app for good. No subscription and no ads.
