6 Best Stethoscopes For Nurses & Emts – 2017 | ResearchCore

What Exactly Is a Stethoscope?

Stethoscopes are undoubtedly one of the most important pieces of equipment for medical professionals. Using a stethoscope, nurses and EMTs can diagnose heart malfunction and detect pulmonary issues before they become serious.

Among diagnostic tools, stethoscopes are most frequently used, and you rarely see a medical professional without a stethoscope. A recent study has also indicated that stethoscopes evoke patients’ trust and confidence.

This article reviews the best stethoscope for nurses, doctors and EMTs, but before taking a look at the best models available, let’s briefly recap the history of stethoscopes and go over the different types of stethoscopes available.

Brief History of Stethoscopes

The very first stethoscope was made by a French doctor, nearly 200 years ago. He used paper and wood to make what was in essence, a listening device. The word stethoscope comes from the two Greek words “stethos” meaning “chest”, and “skopein” meaning “view”. The process of using the stethoscope became known as “auscultation”.

More and more doctors started using this rather rudimentary tool. Only just over 50 years ago, DrLittmann, a Harvard School of Medicine professor, patented a much more sophisticated stethoscope. Today, Littmann stethoscopes are among the most popular.

Stethoscope Types

There are many different types of stethoscopes including acoustic, electronic, fetal, Doppler, cardiology, and pediatric stethoscopes. The vast majority of nurses and EMTs use acoustic stethoscopes, though some may also use electronic stethoscopes.

Acoustic Stethoscopes

Acoustic stethoscopes are the most popular stethoscopes among nurses and EMTs and are considered to be the most reliable. All you need is a good pair of ears, no other equipment is required.

Acoustic stethoscopes work on the principle of sound waves traveling from the chest piece along the tubes and eventually reaching the medical professional’s ears. The bell or diaphragm is placed on the patient’s chest. The chest vibrations are picked up by one or two membranes that transmit the resulting sound along the tube to the medical professional’s ears. The two eartips, or olives, are designed to keep out interfering outside noise and maximize the quality of the transmitted sounds. 

Traditional acoustic stethoscopes have two sides of differing sizes. While the larger side, called the diaphragm, picks up higher frequencies, the smaller side, or bell, is designed to pick up lower frequencies.

Littmann stethoscopes or stethoscopes of similar design are slightly different because they feature dual frequency membranes on the diaphragm and the bell. If a medic wants to listen to higher frequencies, she/he applies a little more pressure and when listening to lower frequencies, the bell or diaphragm is simply placed on the patient.

Medics can use the larger side, the diaphragm, when examining an adult and the smaller side, the bell, for kids or infants.

Most acoustic stethoscopes are specifically designed to maximize the sound quality, while minimizing interference and background noise.

Electronic Stethoscopes

Electronic stethoscopes appeared on the market a few years ago. In essence, the sound quality is superior to acoustic stethoscopes and the accompanying software allows medics to record and analyze the collected data in a considerably more sophisticated manner. The drawback is, however, that auxiliary equipment is required to avail of all the additional features and that’s perhaps the reason most nurses and EMTs prefer acoustic stethoscopes.

Unlike acoustic stethoscopes, electronic stethoscopes require batteries which may be a disadvantage. The electronic stethoscope’s additional features include, sound amplification system to enhance the quality of the transmitted sounds, noise reduction to muffle outside noise or interference, and wireless connectivity as well as relevant software for data recording and analysis purposes.

Electronic stethoscopes are predominantly used by cardiologists, pulmonologists, and other specialists, even though some emergency staff do opt for electronic stethoscopes to avail of the analytical and recording features.

Electronic stethoscopes are considerably more expensive than acoustic stethoscopes.
