EchoRef vs Checklist Navigator

Echocardiography and point-of-care ultrasound organized for the bedside. EchoRef is a comprehensive echocardiography and ultrasound reference for physicians, nurses, advanced practice clinicians, sonographers, medical students, and other healthcare learners. Review TEE, TTE, and POCUS videos, check cardiac measurements and diagnostic criteria, evaluate native and prosthetic valves, and perform commonly used ultrasound and hemodynamic calculations, all in one focused reference. FEATURES • Educational video library covering 2D and 3D TEE, interventional echocardiography, mechanical circulatory support, and clinical cases • POCUS instruction for cardiac, lung, abdominal, vascular, and peripheral nerve block examinations • Cardiac anatomy measurements and reference values for chamber size, ventricular function, diastology, and vascular structures • Native valve assessment for aortic, mitral, tricuspid, and pulmonic stenosis and regurgitation • Prosthetic valve reference for surgical valves, TAVR, and prosthesis evaluation • Ultrasound and hemodynamic calculators for valve area, cardiac output, ventricular function, filling pressures, vascular resistance, shunts, fluid responsiveness, and more • Cardiac equations, hemodynamic reference values, and ultrasound physics • Clinical protocols, focused examination guidance, findings atlas, and reporting documentation • Acquisition guidance, measurement tips, common pitfalls, and related clinical content • Global search, favorites, related links, and personal notes EchoRef connects ultrasound physics, image acquisition, echocardiographic interpretation, and bedside decision-making. Whether you are learning standard views, reviewing an unfamiliar finding, evaluating valve disease, or checking a calculation, the app makes relevant information easy to find.

Surgical safety and anesthesia safety checklists have been proven to reduce mishaps and improve outcomes. Checklists haves also been used to improve the conduct of handoffs and to guide treatment during crises. However, executing checklists in a uniform, reproducible and reliable manner can be difficult. Checklist posters on the procedure room wall can be challenging or impossible to read at a distance, and paper checklists get misplaced. Checklists incorporated into electronic health records are often simple lists, without “smart” functionality. Computerized checklists are widely used in commercial aviation, either built in to the avionics systems, or carried onto the flight deck by the pilots on their ubiquitous computer tablets. The format and function of these computerized checklists have been carefully considered, designed and refined by aircraft manufacturing companies, airlines and test pilots. The authors of this app are anesthesiologists, software engineers, and a commercial airliner test pilot. They have incorporated aviation checklist design principles into this convenient app. Key design elements include ease of navigation, the ability to quickly identify the checklist that is required for a particular situation, a place keeper that automatically highlights the next checklist item, a change in color when checklist items are completed, a change in color of checklist items that are skipped, helping to prevent missed checklists items, which can be a cause of mishaps, and confirmation that a checklist has been completed. In addition to a brief and easily recognized description of each checklist item, a more detailed explanation of each item is also available for reference. In this inaugural version of the app, a limited library of checklists is provided, that will eventually be expanded to include many more checklists, including a full suite of crisis checklists (known as “non-normal checklists” in aviation). Current checklists include— -> Surgical safety checklists (derived from the WHO surgical safety checklists, also known as the procedural“time out”) -> Preanesthesia safety checklist (derived from the APSF preanesthesia checklist) -> Handoff checklist for safe patient handoff between care providers
