The stethoscope is an instrument that is part of the daily life of health professionals from different specialties, such as doctors, nurses, physiotherapists, among others. There are several stethoscope models and values, so we'll help you choose the one that best suits your needs.

Before talking about the models themselves, it is important to put some points on the scale before making your purchase. One of these points concerns your experience using stethoscopes. In this article we will focus on models that facilitate the daily life of the most experienced professionals, adding the highest quality stethoscopes on the market to our list.

If you're still a student, you have two reasons to opt for a simpler model. The first one is for you to get used to the instrument. A simpler stethoscope may have a lower acoustic capacity due to its quality, which makes the person using it has more attention at the time of use. The second reason is the fact that a simpler model does not require a high amount of investment, therefore over time you can upgrade and acquire a more robust model.

Another interesting point to note is choosing a model that is suitable for your specialty and the profile of patients you will serve using this instrument. For example, if your services are intended for children and adults, you can purchase the dual-head model, where on one side there is the larger earpiece that can be used in adults, and on the other side, the smaller head for pediatric care. Otherwise, you can buy the one that best suits your needs.

The most commonly used stethoscopes today are acoustic, and they have great sound quality. However, you can also opt for electronic models, which can amplify the bass sound, thus eliminating any noise that may interfere when evaluating the patient. Another differential of electronic stethoscopes is that some of them allow the health professional to record the auscultation to listen at another time, which allows you to ask questions and make comparisons with other exams.

In terms of durability, it is important to pay attention to the material used in the instrument, such as its rods. Some stethoscopes have shafts made of stainless steel, which is a great option as it is corrosion-resistant because it has chromium in its composition, which inhibits rust. Another alternative is stethoscopes with aerospace aluminum rods, which, in addition to their strength, have the advantage of weight: they are super light.

The shape of the rods must also be evaluated at the time of purchase. Some models have a not so anatomical shape, being straighter in the region that is in the ear. This can be a problem because this format ends up not having a good fixation. In this case, the ideal is to opt for rods that have a good curvature, as this format usually has a better adaptation.

The ear olives also deserve attention, after all, they will be responsible for fixing the rods in your ear and will remain in direct contact with this part of your body. The ear olives can be made of different materials: plastic, rubber, silicone, and even latex. Plastic ear tips usually accompany the simplest stethoscope models, and compared to the others, they tend to be less comfortable. On the other hand, silicone ear tips are usually the most suitable, because, in addition to being more comfortable, They are also made of an anti-allergenic material.
