The term auscultation comes from Latin and refers to the act of hearing. The auscultation of the veins and arteries is, therefore, to listen to different noises from these blood vessels through specific devices in order to facilitate the diagnosis of different pathologies.
Ultimately, auscultation is a clinical examination method whose purpose is to appreciate different physical phenomena. It can be carried out by direct application to the ear or thanks to a stethoscope or phonendoscope.
It is possible to listen to many parts of the human body, such as the heart, respiratory or digestive systems. In this article, we are going to focus on the auscultation of the veins and arteries.
Auscultation of the veins
Veins are blood vessels responsible for conducting blood from the blood capillaries to the heart. They generally carry cell waste and CO2, although the arteries carry oxygenated blood.
The pulmonary arteries carry oxygenated blood from the lungs to the chambers on the left side of the heart. When filled, this organ pumps blood to the rest of the body through the aorta artery and umbilical veins.
In the normal state, no perceptible acoustic phenomena occur in the veins. However, in certain situations, murmur or murmur noises may be seen in the jugular veins. For example, this occurs in the case of anemia, a pathological situation in which the blood does not carry enough oxygen; or chlorosis, a disease in which there is iron deficiency in the blood.
These noises are distinguished by being continuous; when there is intermittence, it is not rhythmic and can be assessed by auscultation of the veins and arteries.
