A question we get asked a lot is “What does an electronic stethoscope do?” And more importantly, how are they different from traditional stethoscopes? The technology is relatively new, and because of this, every model works slightly differently.
Signal collection & transmission
But they aren’t really different from traditional stethoscopes in that the signal collection, transmission, and amplification aren’t really electronic. The key difference is that they rely on a mechanical engineering principle called the ‘microwave’ principle. In short, the vibrations of the stethoscope’s needle against the skin are interpreted by the electronic stethoscope’s built-in microphone. These signals are then amplified by a transceiver device onto a speaker system and sent up to a central data unit. The transmitted signal is then amplified many times, which gives an audio signal. Because of this, any background noise is cancelled out by the inherent properties of the signal.
What does an electronic stethoscope do?
With that understanding of how an electronic stethoscope works, we can now move on to the next question, what does an electronic stethoscope do? Well, let us tell you, it’s quite a lot. First of all, electronic stethoscopes are used to listen to extremely low-frequency sounds (hence their name), which are impossible to hear using a traditional stethoscope. Another application is to amplify medical noises such as thumping hearts, lung infections, or other serious medical problems. In addition to these applications, modern electronic stethoscopes are also used for aesthetic reasons, for listening to and reading body temperature monitors, hearing aids, and even computer monitors.
There are three main types of electronic stethoscopes: acoustic, mechanical, and digitally amplified. Acoustic stethoscopes use the sounds of the lungs as the signal to amplify them. This type of stethoscope has a tube-like shape and two narrow headpieces with two earpieces (one behind the other). The tube expands as the air is breathed in, forcing a large amount of air to travel through the tubes. The mechanical type uses electric motors to mechanically expand the tube and make the desired sound waves.
Digital stethoscopes, as the name suggests, are digital and thus contain digitized versions of the physical properties of the lungs. With this digitalized version, the stethoscope records the signal in a digital signal. This makes the stethoscope useful for medical applications such as cardiac catheterization and lung volumes analysis. It can also measure blood pressure and blood oxygen saturation. However, digital stethoscopes are not appropriate for measuring patient characteristics such as blood pressure or respiratory rates because of the large inaccuracies that may occur when using the measurements.
Both types of stethoscopes may be used to measure and interpret medical signs and symptoms. However, patients should not feel forced to use either type if it does not suit their needs. A patient’s own preference should always be considered when purchasing a medical device. Patients should look at both analog and digital models to ensure that they will be comfortable using them. There are many brands that produce both types of the electronic stethoscopes.
Some stethoscopes can have additional features such as alarms, timers, dials that light up, and additional buttons and ports that can be very useful for medical professionals. The additional features that an electronic stethoscope may have may be very helpful for patients who are experiencing certain medical symptoms. Some examples of these additional features include alarms, timers, special effects, and portability.
Many health care professionals agree that there is a significant difference between the two different types of stethoscopes. When choosing an electronic stethoscope, it is important for you to consider how comfortable you are with its operation and how well it is able to convey your medical data. Some people may prefer to use traditional stethoscopes for medical procedures such as cardiac stethoscopy or lung function analysis. However, others may feel more comfortable using electronic stethoscopes for different applications such as dental x-rays or lumbar punctures. Deciding between the two types of stethoscopes will help you make an informed decision.
There are many advantages of using a stethoscope including taking a sample of your blood and checking out your temperature. These new electronic stethoscopes have made all the hard diagnosis simple. Don’t confuse electronic stethoscopes with normal stethoscopes, because both are different.
These stethoscopes have become very popular around the globe, and they are used for various reasons. Many hospitals use a stethoscope to hear heart murmurs; they can hear irregular heartbeats from the ear tips and can check out the level of oxygen in the patient’s bloodstream. Doctors also use a stethoscope to hear children’s heart sounds to make sure that the baby is healthy and there is no problem in the mother’s pregnancy. This stethoscope is used in dentistry too. And nowadays even housewives can listen to their husbands’ heartbeat through a stethoscope.
Some advantages of these electronic stethoscopy machines are: they are portable, you can hear all the inner ear sounds, and they are FDA approved. Some disadvantages of using a stethoscope: if you are moving or having a hard time breathing, it is hard to hear external hemorrhoids, inflated venous, rare blood clots in the vein, or hear lung sounds. Some users feel a little uncomfortable with the earphones, especially when there is a lot of noise. Some users find it easy to get used to the earphones, while others find it uncomfortable and need to constantly re-plug the stethoscope.
