POCUS Tips is a bedside point-of-care ultrasound reference covering the core cardiac, lung and IVC views used in acute care: how to get each view, what normal and abnormal look like, common pitfalls, and what a finding changes about management.
It's maintained as a teaching aid and quick-reference guide, built from standard bedside ultrasound teaching. More about the author and other work is at yonathan.online.
Frequently asked questions
- Is POCUS Tips a clinical decision tool?
- No. It is a teaching aid and quick reference. Nothing on the site is intended for diagnosis or treatment decisions; confirm findings with formal imaging and clinical judgment.
- Who is it for?
- Acute-care clinicians and trainees learning bedside cardiac, lung, IVC, aorta and trauma ultrasound: emergency medicine, critical care, anaesthesia, acute medicine and the students rotating through them.
- Where do the numbers and cut-offs come from?
- Chamber and vessel cut-offs follow the ASE chamber quantification guideline (2015) and the ASE right heart guideline (2010); lung ultrasound logic follows the BLUE protocol and the international lung ultrasound consensus; shock and trauma protocols follow the RUSH exam and eFAST teaching. They are starting points for learning, not thresholds for action.
- Does it work offline?
- Yes. After the first visit the pages, loops and quiz are cached by a service worker, so the site opens without a connection. Quiz progress is stored only in your browser.
- Where do the ultrasound loops come from?
- Loops are credited on each view to The POCUS Atlas, Ultrasound Idiots and Pocus 101; a few clips are used with the personal permission of contributors who prefer not to be named. Views without a licensed loop show a clearly labelled schematic diagram instead; no ultrasound images are generated or fabricated.
- How do I report an error?
- Contact the author through yonathan.online. Clinical corrections are reviewed against the source guidelines before they are published, and each page shows the date it was last reviewed.
