mediate auscultation การใช้

• Originally, there was a distinction between immediate auscultation ( unaided ) and mediate auscultation ( using an instrument ).
• Professor Benjamin Ward Richardson stated in " Disciples of Aesculapius " that " the true student of medicine reads Laennec's treatise on mediate auscultation and the use of the stethoscope once in two years at least as long as he is in practice.
• Laennec called his device the " stethoscope " ( " mediate auscultation ", because it was auscultation with a tool intermediate between the patient's body and the physician's ear . ( Today the word " auscultation " denotes all such listening, mediate or not . ) The first flexible stethoscope of any sort may have been a binaural instrument with articulated joints not very clearly described in 1829 . In 1840, Golding Bird described a stethoscope he had been using with a flexible tube.
