(15) Diagnosis is made by following the classical physical diagnostic procedures of inspection, palpation, and auscultation.
(16) The ability of the auscultated acceleration test to predict nonstress test results after selected variables were controlled for was as follows: sensitivity, 75%; specificity, 97.6%; false-positive results, 14.3%; and false-negative results, 4.7%.
(17) As regards auscultation, a plea is made for differentiation between obstructed and non-obstructed consolidation of lobes, a point recognized by some clinicians, but not enunciated with clarity by teachers.
(18) The forceps delivery rate was 8.2% in the electronic fetal heart monitoring group compared with 6.3% in the intermittent auscultation group, and this excess was explained by more instrumental deliveries prompted by fetal heart rate abnormalities.

(20) Twenty-seven of these 30 joints were treated with the appliance until the joints were silent to auscultation.
Stethoscope
Definition:
(n.) An instrument used in auscultation for examining the organs of the chest, as the heart and lungs, by conveying to the ear of the examiner the sounds produced in the thorax.
(v. t.) To auscultate, or examine, with a stethoscope.
Example Sentences:
(1) A specially designed acoustic stethoscope electronic-computer-analysis system has repeatedly detected and identified angiographically demonstrated anteriorly located intracranial aneurysms by their characteristic signals.
(2) The response of stethoscopes and chest microphones depends on the impedance of the sound source, which must therefore have the same impedance as the body, and must emit a signal related to the sound intensity in the body when no instrument is applied.

(6) Selective use of the open-bell and diaphragm sound chambers is assured with this new stethoscope.
(7) With the help of a child's stethoscope and a tuning fork of 128 Hz, the sound conducted by an injured limb was compared with that by the uninjured limb.
(8) The importance of frequency components outside the bandpass of the stethoscope is stressed, especially in terms of the possibility of yielding more clinical information and, perhaps, additional clues above the origin of the Korotkoff sounds themselves.
(9) Twenty-one anesthesia clinicians evaluated the stethoscope and responded to a multiple-choice preference questionnaire.
(10) Three readings by two observers using a double stethoscope were first compared to each other to determine a standard and then averaged and compared to readings obtained using the P4.
