4 common types of stethoscopes

You will rarely come across any physician who doesn’t carry a stethoscope with them. In fact, it is one of the most important devices of daily medical practice. A stethoscope is a medical device that every paramedic, nursing student, medical student, and the doctor should possess in person. Though the traditional stethoscope helped the doctor listen to the bodily functions like the heartbeat, the respiration, or the digestion, the modern day stethoscopes differ according to their application.

The function of a good stethoscope is to allow you to perform the fundamental tasks like auscultation with the intention of assessing the condition of the thoracic organs, abdomen, and blood vessels. However, one stethoscope cannot be used to check different conditions, which is why there are different types of stethoscopes. The different types of stethoscopes include:

Cardiology stethoscope
Though this stethoscope looks like a regular stethoscope, it has the ability to give excellent acoustic sound quality. Also, it is accompanied by the ability to hear both low- and high-frequency sounds from the diaphragm, and you wouldn’t have to use a bell, which is commonly found in dual-headed stethoscopes. Moreover, these stethoscopes have thicker earpieces that block out unwanted noise and prevent any interference with the auscultation, which is why it is used to listen to heartbeats, S2, and murmurs.

Infant stethoscope
This type of stethoscope is used for newborn babies and are the smallest of the kind. It has a very small diameter of about 2cm that ensures that the auscultation is accurate and the surrounding noise doesn’t interfere with it. These stethoscopes are available in non-latex forms to avoid allergic reaction in infants and have a non-chill ring as well.

Electronic stethoscope
These stethoscopes can help solve sound problems as they amplify the sound obtained from the chest-piece electronically and then convert it into electric waves that are transmitted through particular circuits. When the electric waves pass, they are processed for better listening. These stethoscopes are available in two categories, namely, the amplifying and the digitizing stethoscopes.

Teaching stethoscope
As the name suggests, this stethoscope is used primarily for teaching purposes. It features a single-lumen tubing that is highly durable and comes with solid stainless steel chest piece and has a dual headset. This feature allows the teacher and student to use the stethoscope at the same time and the students gain a better understanding of what’s happening to a patient.

  • 4 popular courses that teach you about human anatomy
    The study of tissue structures and organs in organisms including animals and humans is called anatomy. Although ancient civilizations studied human anatomy, the practice of human anatomy illustrations started quite late in the domain of medical science. It was mostly because cultural norms and religious beliefs prevented people from exploring and illustrating the human anatomy in depth. There were a lot of restrictions on the human body dissection, which was considered a debasement. So, there were hardly any realistic human anatomy illustrations. This changed in the fourteenth century when Andreas Vesalius put forth his seven-volume work called De corporis humani fabrica libri septem, which is roughly translated to On the Structure of the Human Body. In this volume, Vesalius incorporated human anatomy illustrations and texts based on actual dissections. After this, the study of human anatomy acquired a scientific method. Another important work of modern anatomy has been Gray's Anatomy, which was published in 1858 by Sir Henry Gray, an English surgeon.

  • Why should I invest in stocks
    While investing in stock markets is luring, it is just as risky. All the money that you could gain could just as easily be lost. So, one could very easily be convinced not to invest in stocks. However, they have their charm, their surprise elements and most importantly they don’t constitute every penny you make but only a part of it. So, here’s why you could consider investing in stocks: Growth happens with time, even in the case of stocks. One might not realize the importance of this growth in financial savings, but stock investments give meaning to it.  Money invested for a longer duration will higher the chances for it to grow. This long term growth of money is possible in many ways, one of which is investing in stocks. This stock investment could even be made by signing up for retirement plans like 401(k) which would be sponsored by your employer. Although there are constant ups and downs in the market, which could stir up quite some tension, potential growth has been seen in the case of the stock markets over the years. Money invested in stock markets has shown to give significant returns comparatively over a good length of time. While planning on a retirement plan, it is hence important to invest a part of it in stocks. It is quite common for one to worry about the losses one might incur in this field. However, if the stock market can be trusted for its erratic behavior, there are good chances you’ll come out of it. This is why stocks are long term investments. Although it could take time to recover, stocks still seem to be the better option. Another perspective would be that your losses in stocks are not losses until they are sold. Just as one wouldn’t spend their savings for future now, it would be advisable to hold on to stocks even during their losses. Finally, all your time and money doesn’t go into stocks. You’d rather invest and get the greater amount out of it than go for other less paying options.
