High Quality Content by WIKIPEDIA articles The stethoscope is an acoustic medical device for auscultation, or listening to the internal sounds of an animal body. It is often used to listen to lung and heart sounds. It is also used to listen to intestines and blood flow in arteries and veins. In combination with a sphygmomanometer, it is commonly used for measurements of blood pressure. Less commonly, mechanics stethoscopes are used to listen to internal sounds made by machines, such as diagnosing a malfunctioning automobile engine by listening to the sounds of its internal parts. Stethoscopes can also be used to check scientific vacuum chambers for leaks, and for various other smallscale acoustic monitoring tasks. A stethoscope that intensifies auscultatory sounds is called phonendoscope.

Nasco KERi Auscultation Manikin

$3995

Features of the Nasco KERi Auscultation Manikin: For auscultation training, the instructor selects from a menu of heart and lung conditions by wireless remote control. The manikin presents itself as a real patient without visible auscultation sites. The student must palpate to identify correct auscultation locations, and will hear different heart and lung sounds as the SmartScope™ is moved to different locations on the manikin. A diagnosis of the condition selected by the instructor can be made by comparing the variations in sounds occurring at different sites - just like a real patient! Lung sounds can be detected at five anterior and 12 posterior locations and students can practice auscultation at six anterior heart sites. The remote control does not have to be pointed directly at the manikin or SmartScope™ to operate. One remote control will operate multiple sets of SmartScopes™ and manikins simultaneously. Great for group instruction. Listen to the sounds by using either the single- or dual-user headpieces on the SmartScope™ or connecting to an amplified speaker (not included, see SB20146U). Range on the unit is up to 100 ft. of remote access. Each trainer includes manikin, one remote control with LCD display, and one SmartScope™ with single- and dual-user headpiece. Requires two “AA” and two “AA” batteries (included). Three-year warranty.Has all the same features as the Complete KERi™ Manikin (LF04020U) and:Heart Conditions:* Normal* Aortic Regurgitation* Mitral Stenosis* Pulmonary Stenosis* Holosystolic* Mid Systolic* S3 Gallup* S4 Gallup* Systolic Click* Atrial Septal Defect* PDA* VSDLung Conditions:* Normal* Wheeze* Mono Wheeze* Fine Crackle* Rhonchi* Stridor* Bronchial* Coarse Crackle* Cavernous* Pulmonary Edema* Friction Rub* Pectoriloquy
