Resumen

With the growing use of point-of-care ultrasound (POCUS) in various clinical settings, it is essential for users of ultrasound to have a thorough understanding of the basics of ultrasound physics, including sound wave properties, its interaction with various tissues, common artifacts, and knobology. The authors introduce and discuss these concepts in this article, with a focus on clinical implications.
