3M Littmann Cardiology III Stethoscope Review


This review will focus on a model that is popular with most healthcare workers. It’s is a model that clinicians globally identify with as it has been around for a long time. We’re going to discuss the most controversial things about it, point out features that uniquely identify it and why you should consider buying one.

As you already know, a stethoscope is a must-have tool for medical practitioners. It is the first tool that helps in patient assessment, especially listening to internal sounds like heart beat. Though recent developments have seen the evolution of an electronic version of the stethoscope, traditional versions have never run out of popularity and are still a number one preference for medics.

Why Medical Professionals Need Stethoscopes

Medical personnel need stethoscopes for various activities. Some of these include:

  • Blood pressure Monitoring

Stethoscopes are used to monitor a patient’s blood pressure. Usually, the clinician will place the flat end (diaphragm) below the patients cuff to listen to how blood is pumping through their veins. This will help to determine the patients’s blood pressure rate.

  • Determining heartbeat count

Sometimes, there is need to assess how fast a patient’s heart is beating. Heartbeat sounds are impossible to hear analytically by the normal ear. Irregular sounds from the heart, even smallest of murmurs, are magnified when a good quality stethoscope is used.

  • Lung assessment

Sometimes doctors need to study the lungs for abnormal breathing or presence of moisture and other liquids. During the cold seasons especially, colds often cause the sinus to drain fluids, which can cause congestion in the lungs.

  • Stomach assessment

Some medics will use a stethoscope to listening to sounds emanating from the intestines.

A good quality stethoscope is highly sensitive. The 3M Littmann Cardiology III model has been praised for this.  Some medics even profess to being able to listen to sounds even in the presence of clothing using the stethoscope.

Despite the numerous applications of the stethoscope, it can present risks for both you and your patient. Incorrect diagnosis has often occurred when sounds were misinterpreted. Therefore, you should first master all body sounds so that you can take full advantage of this tool when it magnifies those same sounds.

The Littmann stethoscopes are the best stethoscopes for doctors, nurses and students. Although somewhat highly priced, this brand will help you make the correct diagnosis. The Littmann Cardiology III can magnify sounds up to five times five. This has made it popular with spies and exterminators.
