ARRIBAS DIAZ, Ana Begoña  e  VELA ORUS, Pilar. Doppler ultrasound exploration optimization by manipulating the controls of the equipment: knobology; part two. Angiología [online]. 2023, vol.75, n.6, pp.373-384.  Epub 29-Jan-2024. ISSN 1695-2987.  https://dx.doi.org/10.20960/angiologia.00443.

Doppler ultrasound is an operator-dependent diagnostic modality, essential due to availability, efficacy, costs and non-invasive test. In addition to anatomical and clinical knowledge, it requires a minimum knowledge of its physical and technological principles. This article attempts to review and outline how to adjust the main applications of the equipment in Doppler scanning, using the buttons and controls (knobology). It complements the first part already edited, where the adjustments in the exploration in B mode were explained.

Carrying out an examination with a suitable posture, which avoids injuries to the explorer (ergonomics), also allows us to increase our work performance.

Knowing, training and adjusting the echo Doppler functions in an orderly manner, considering the patient and the indicated study, will make our examinations easier, faster, safer and more precise.
