Inhalation can be confirmed by one or more tests such as using a stethoscope to listen for abnormal lung sounds ( diffuse crackles and rhonchi ), performing blood gas tests to confirm a severe loss of lung function, and using chest X-rays to look for patchy or streaked areas on the lungs.

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.

Cammann also wrote a major treatise on diagnosis by auscultation, which the refined binaural stethoscope made possible.

Most murmurs can only be heard with the assistance of a stethoscope (" on auscultation ").

** 2: The murmur is faint but immediately audible on placing the stethoscope on the chest.

On physical examination, breath sounds ( audible using a stethoscope ) may be diminished on the affected side, partly because air in the pleural space dampens the transmission of sound.

They resurfaced the mirror on 3 February and worked out a way of pointing the telescope using a stethoscope, stopwatch, and the noises the moving mirror made in its casing.

PPS with respiratory involvement requires special management such as breathing exercises, chest percussion with a stethoscope on regular occasions for observation of the disease and management of secretions.

He also gained a greater reputation after winning Harvard Medical School's prestigious Boylston Prize, for which he submitted a paper on the benefits of using the stethoscope, a device with which many American doctors were not familiar.

Auscultation ( based on the Latin verb auscultare " to listen ") is the term for listening to the internal sounds of the body, usually using a stethoscope.

I came into the office with a stethoscope and surgical greens I had left over from The Human Factor series on which he'd previously performed.

For centuries, physicians have employed many simple non-invasive methods based on physical parameters in order to assess body function in health and disease ( physical examination and inspection ), such as pulse-taking, the auscultation of heart sounds and lung sounds ( using the stethoscope ), temperature examination ( using thermometers ), respiratory examination, peripheral vascular examination, oral examination, abdominal examination, external percussion and palpation, blood pressure measurement ( using the sphygmomanometer ), change in body volumes ( using plethysmograph ), audiometry, eye examination and many others.

* auscultation ( with stethoscope )-bruit (" rushing " sound ) on affected side, inferior of the costal margin

The diagnosis is based on the sound heard by listening through a stethoscope placed outside the abdominal cavity.

2004, along with Philips ' brand ( manufactured by Andromed, of Montreal, Canada ) electronic stethoscope model.

Conversely, restricting excursion of the diaphragm by pressing the stethoscope diaphragm surface firmly against the anatomical area overlying the physiological sounds of interest, the acoustic surround could also be used to dampen excursion of the diaphragm in response to " z "- axis pressure against a concentric fret.

An electronic stethoscope ( or stethophone ) overcomes the low sound levels by electronically amplifying body sounds.

However, amplification of stethoscope contact artifacts, and component cutoffs ( frequency response thresholds of electronic stethoscope microphones, pre-amps, amps, and speakers ) limit electronically amplified stethoscopes ' overall utility by amplifying mid-range sounds, while simultaneously attenuating high-and low-frequency range sounds.

Moulded earpieces can be cast by an audiologist or made by the stethoscope user from a kit.

The pulse can also be measured by listening to the heart beat directly ( auscultation ), traditionally using a stethoscope.

That perception might be either with the unaided human sense or with the aid of an instrument, e. g., microscope or stethoscope, or by other scientific means, e. g., a chemical reagent which changes color in the presence of a particular substance.
