Every medical worker who interacts with patients requires a stethoscope, and since David Littmann first improved personal diagnostic equipment in the 1960s, Littmann Stethoscopes have been the best available.
Even now, they continue to advance with new features and improvements while being owned by the American business 3M. Stethoscopes made by Littmann are available in a range of forms, styles, and pricing ranges.
In order to assist you to choose which model is best for you, we’ll analyze the cost to benefit of the most popular models in this post.
How to Choose a Stethoscope
Make sure you can hear, see, and feel the difference before you invest in a stethoscope.
There is no replacement for testing out several stethoscopes while you are stethoscope shopping. Ask coworkers whether you may use their stethoscopes to listen. Clean the ear tips before and after usage, of course.
View the characteristics. See if it is simple or difficult to adjust the headsets. Most likely, a 3M Littmann® Stethoscope will provide all you need and more.
Here is a breakdown of a stethoscope’s
The true test is how much you can hear. Put a Littmann stethoscope on (make sure the eartips point toward your nose). Apply mild pressure to your chest when placing the adjustable diaphragm there. Listen to your heartbeat. Take note of how loud it is.
How loudly is it? louder by more than four times. An internal 3M test revealed that heart sounds detected with a Littmann stethoscope’s adult diaphragm were more than four times louder (20 dB) than those detected using a stethoscope from a different manufacturer. That’s comparable to the distinction between talking and whispering. It can mean the crucial difference between a patient hearing anything important or not hearing anything at all.
Listen to others once you’ve listened to yourself. Review websites online. Inquire of those that utilize Littmann stethoscopes.
There are several accounts of people who rely on Littmann stethoscopes because they can tell the difference with ease.
The Basics of Littmann Stethoscopes
Before you get right into selecting a Littmann stethoscope, you need have a basic understanding of how they operate, the key components, and how variations in those components impact the stethoscope’s quality.
The chest portion of a stethoscope is its most crucial component. It might either be a bell or a diaphragm that touches the patient’s skin in this area.
A membrane is spread over a hollow space in a diaphragm. The air within is moved as the membrane vibrates, resulting in pressure changes that our ears perceive as noise.
The sound is amplified because more air must pass through the tube since the membrane’s surface area is greater than the tube’s cross-sectional area.
Bells function similarly to diaphragms, but a bell’s hollow chamber is not covered by a membrane. Bells have historically been used to detect low frequency noises.
There are 3 distinct types of chest piece adapters included with Littmann stethoscopes:
Tunable Diaphragm: By varying how firmly the chest piece is placed against the skin, the frequency of the sound heard may be altered. For hearing low-frequency noises, use low pressure, while for hearing high-frequency sounds, use high pressure.
Pediatric Diaphragm: A smaller diaphragm that, depending on the type, may or may not be adjustable. The pediatric diaphragm can be transformed into a bell by removing the membrane.
Bell: Like structure, the bell is smaller and devoid of a membrane. To hear low-frequency noises, use the bell.
Littmann Stethoscope Holders and Accessories
Stethoscope Holder –
There are several practical holsters that can be attached to a waistband/pocket or threaded through a belt loop if you don’t prefer to follow the stethoscope-around-the-neck cliche or work with aggressive mental patients.
Stethoscope Case –
It would be a pity to damage a fine stethoscope after spent a lot of money on it by smushing it beneath books or puncturing the diaphragm as it rolls around in a suitcase with the rest of your belongings.
Your Littmann stethoscope is shielded from harm by a sturdy case, which also functions as a bag to collect trinkets. Personally, I like the hard case with a zipper.
Stethoscopes with a single lumen work well in this circumstance. All stethoscopes made by Littmann Cardiology contain double-lumen tubing. If kept in the case for a long time, double-lumen tubing may break or distort.
