What is a cardiological stethoscope?
Cardiological stethoscope is a specially designed stethoscope for the use of doctors and nurses in the field of cardiology and cardiovascular surgery. Its construction allows greater ability to hear both low -frequency sounds, necessary, because they study the heart in this discipline and have to hear liquid blood pumping over four chambers and four heart valves. The regular stethoscope is designed to allow the user to listen to the inner functioning of the body such as heart rhythm, pulse in the limb, intestinal sound or liquid in the lungs. The cardiological stethoscope allows the user to listen and identify specific sounds of the heart, such as clicks, mutters and friction. Compared to a conventional stethoscope, the cardiological stethoscope has a stronger and much shorter tube between the headphones and the membrane, the round button at the end of this tool. This shorter distance for sound to travel and thicker enhanced hoses enable the user auscultate or listens to a wider variety of body sounds. A shorter pipe of cardiologicalThe stethoscope also avoids the problem common to regular stethoscopes of longer lengths: the interference of a clear auscultation caused by friction of the undulating tube against each other because it does not slide unless it is pulled out.
Cardiological stethoscope also has a heavier and better designed headset, which is usually more comfortable than a conventional stethoscope. The groups of ears are larger and stronger for sealing the ambient noise during auscultation. The round diaphragm is usually made of stainless steel, unlike the plastic membrane of a conventional stethoscope. These design functions also work to improve the audio transmission and quality of cardiology acoustics.
Cardiology acoustics is often gentle and takes a lot of tij and I can handle. In addition to the Daum of every heart rhythm-formally referred to as s1 and s2 -other sounds such as mummarks, clicks and friction. Commonly known term heart murmur The tangent sound of the heard when the valves do not work properly and blood leakage is audible using a cardiological stethoscope. The degree of auscultation capable of a trained healthcare professional using this type of facility allows sorting of murmurs along the continuum from one to four.
cardiological stethoscopes are expensive. The purchase price for one diameter is around $ 160 (USD), while a cheap stethoscope can be purchased for only $ 10. The name of the engraving on the stainless steel membrane is often offered for a cardiological stethoscope to avoid deliberate theft or even unintentional mixing between similar looking tools.
