Do you have the daunting task of buying a stethoscope for the first time? Perhaps, you are just beginning to sell to healthcare clients and want to better educate yourself on which scope works best for the intended use. At Spectrum, we understand the importance of selecting the right stethoscope. Often, the accuracy of your diagnosis depends on it!

It is easy to feel overwhelmed with the range of choices available. With this beginner’s guide for nurses and other healthcare professionals, we can help guide you to pick what is best for you or your client.

First Stethoscope as a Student

The need for a stethoscope for students will vary depending on the field of study and specialization―as well as the level of training. For instance, a stethoscope required for a high school student in a HOSA or other healthcare related program will differ from what is needed in a first year nursing program. Either way, if you are not too familiar with stethoscopes, the best rule is to keep things simple.

The two most basic factors to consider before buying a stethoscope are functionality and price. You will also want to understand the parts of a stethoscope, as each of them have specific functions.

Parts of a Stethoscope

The basic parts of a stethoscope are the earpiece, tubing (along with its length and shape) and the chest piece. Nowadays, stethoscopes also come in an electric or standard form. You must know that electric scopes―despite their high-end look―are not suitable for everyone.

Earpiece

Finding the correct size of earpiece which fits you is crucial. It will determine the quality of sound you hear when you use the stethoscope and your comfort as well. Most brands provide you with a couple of choices when it comes to the earpiece, which can help ensure the right size for you. In case the stethoscope you choose doesn’t have the correct size for you, you can buy a more custom-fitted earpiece online for just a few dollars. The ideal stethoscope must have a snug fit rather than a tight fit, which might drown the internal sounds of your patient. 

Tubing and Length

Stethoscopes are available in various sizes, ranging from 22-31 inches (55-80 cm). The most popular length is 27 inches (70 cm). Some medical practitioners do not have any preference when it comes to the length of their stethoscopes. But, bear in mind, 27 inches will allow both the examiner and the patient to retain their personal space. A long tube length is also favorable for you as you will not have to lean forward each time you use your stethoscope.

If you are concerned about diminished sound quality while using a longer stethoscope, it is helpful to note that the National Institute of Health has ruled out this assumption.

You will also want to have a tube made with a thicker material. Thinner material in the tubing will wear out soon and might be prone to cracking. Check for any kinks or bends in the tubing while buying the stethoscope.

Chest piece

The chest piece of a stethoscope consists of a diaphragm and a bell. The diaphragm is designed to be flat and is used to look for high-frequency sounds made by the heart, lungs or intestine. The part of the chest piece is also functional in measuring the blood pressure when used with a sphygmomanometer (blood pressure gauge). You can find some basic stethoscopes with a diaphragm that has a single-sided chest piece.

The small curved side in the chest piece of a stethoscope is known as the bell. This part of the stethoscope is built to pick up low-frequency sounds such as heart murmurs. Pediatric practitioners often use this part of the stethoscope for their patients.

Shape

Almost all stethoscopes have two “ears” and have a single tube that connects them to the chest piece. But other options are also available, depending on your use. If you are taking a blood pressure reading, you will want an oval chest piece to fit easily under the cuff. The shape of the chest piece has no impact on the overall sound quality.

Spectrum Dual-Head Stethoscope - SM100 

(Recommended for young students and household use)

This economical Spectrum option is ideal for first-time students who are just being introduced to healthcare professions―it also makes an ideal option to have in a well-stocked home medicine cabinet. It offers a dual-sided chest piece to provide quality acoustic sensitivity for both high and low frequency noises. You can listen to, and study heart, lung, and other body sounds in children and adults.

Squeezing together or pushing apart the ear tubes adjusts the tightness of the headset for head size and convenience. Tight, soft-sealing ear-tips adjust to individual ears for a comfortable fit and acoustic isolation. Ear-tips snap firmly to the ends of the ear tubes and for safety reasons, require a little bit of effort when removing.

This workhorse of a stethoscope comes with five interchangeable chestpiece fittings to offer the most versatile diagnostic capabilities, making it a great choice for nursing students.

The Sprague stethoscope binaural is entirely adjustable, allowing for a totally tailored, angled fit. Pressure can be altered as well; ease by gently drawing the aural canals apart or near to tighten it around the eardrum. The Sprague models use a two-tube configuration.
