3M Littmann Cardiology III Stethoscope Review 2017

In this review, we’ll discuss about the features, benefits and disadvantages of using 3M Littmann Cardiology III stethoscope. This model has been around for years and it’s been used by millions of healthcare professionals worldwide.

Stethoscope, per se, is a fundamental tool that allows medical professionals to find out if their patients have abnormalities through their breathing and beating. Although electronic versions of stethoscope are gaining in popularity, the majority of medical professionals still opt for the older, traditional versions.

This medical tool has several functions in the medical field. It’s a handy instrument that doctors, nurses and other healthcare professionals carry around their necks.

One of its main uses is to check blood pressure. When checking for blood pressure rate, the flat end of this tool will be placed under the cuff to hear the pumping blood through your vein. It’s also used to count the heartbeats. Those sounds can’t be heard by your normal human hears. Hence, stethoscope becomes an invaluable tool for this type of task.

Another main use of it is to listen to your lungs. Your healthcare provider will know whether or not you’re breathing clearly. If you’re not, he/she will know if there’s congestion or too much liquid in your lungs. Congestion in your lungs is usually caused by sinus fluid drains during colds.

Heart murmurs and other irregular heart sounds can be heard as they’re magnified through a reliable stethoscope, like Littman Cardiology III. It’s a small tool yet a dependable device to be used as the first step in identifying whether or not you have heart damage.
