Romanian term (edited): frecatura bazala

Sau "basal friction rub".

În lipsa unui context mai detaliat, presupun că e vorba de frecătură pleurală la baza plămânului. Sunetul poate fi ascultat la http://medikal.ro/sunete.html

"Pleural friction rubs are low-pitched, grating, or creaking sounds that occur when inflamed pleural surfaces rub together during respiration. More often heard on inspiration than expiration, the pleural friction rub is easy to confuse with a pericardial friction rub. To determine whether the sound is a pleural friction rub or a pericardial friction rub, ask the patient to hold his breath briefly. If the rubbing sound continues, its a pericardial friction rub because the inflamed pericardial layers continue rubbing together with each heart beat - a pleural rub stops when breathing stops.

"Clinical examination was normal, except for a dullness on percussion, diminished breath sounds, and pleural friction at the right base of the thorax. " http://erj.ersjournals.com/cgi/reprint/10/9/2171.pdf
