STETHTRON - The High-Fidelity Electronic Stethoscope
Stethtron is quite different from the conventional stethoscope. It has a built-in miniature amplifier inside the chestpiece. This electronic stethoscope makes medical auscultation diagnosis easy. Heart sounds, respiratory sounds and murmurs are heard loud and clear. The faint murmur or abnormality that are often missed by the regular stethoscope are easily be detected with Stethtron. Light and compact, it gives upto ten times the amplification compared to the regular stethoscope.
Other advanced features of Stethtron are :- Graduated volume control, electronic filter, noise reduction circuitry, feather-touch switches / ear-tips for extra comfort and a non-chill rim.
Auscultaion is easy ! Diagnosis is simple and more reliable
Loud and Distinct I,II,II,&IV heart sounds
Crystal-clear respiration sounds and cardiac murmurs
Stethoscopes, like any other medical instrument, have undergone a lot of variations and enhancements. These enhancements have mainly been carried out to ensure that doctors and other medical practitioners do not have any trouble whatsoever listening to body sounds while examining a patient. In the past and even today, the most commonly used stethoscopes are the acoustic ones. These stethoscopes transmit sound from the chest piece, via the hollow rubber tubes, to the ears of the listener. The chest piece normally consists of a diaphragm on one side and a bell or hollow cup on the other side to listen to the various body sounds of a patient. If you place the diaphragm on the body of a patient, the body sounds produce vibrations on the diaphragm creating sound waves that travel through the hollow rubber tubes to the ears of the listener. On the other hand, if you place the bell on the body of a patient, the vibrations on the skin directly produce sound waves that travel to the ears of the listener. The diaphragm is used to transmit high-frequency sounds whereas the bell is used to transmit low-frequency sounds. However, the major problem with acoustic stethoscopes is that the sound level is extremely low and can be a major concern in noisy environments.
This issue resulted in the evolution of the electronic stethoscope.
An electronic stethoscope overcomes the issue of low sound level by amplifying body sounds to a level where it can be comfortably heard by the listener. The whole process includes converting sound waves to electrical signals, which can then be amplified and converted back to sound waves for optimal hearing. An electronic stethoscope comes along with a lot of benefits. Some of these benefits are:
Sound Amplification: An electronic stethoscope comes with an amplified mode and the volume can be adjusted.
This enables doctors and other medical practitioners to set the preferred amplification for each patient. They have the option to increase the volume level for faint body sounds, for obese patients, or for an environment where there is a lot of noise. The volume of an electronic stethoscope can also be adjusted to a moderate level for children because they have loud heart sounds.
Crystal Clear Sound: An electronic stethoscope converts body sounds into electrical signals, which are then processed for crystal clear hearing. Therefore, there is no sound loss in the hollow rubber tubes, as in the case with acoustic stethoscopes.
Easy Switching between Modes: With an electronic stethoscope, you do not need to remove and flip the chest piece to switch between the diaphragm and bell modes. The instantaneous electronic switching in these stethoscopes makes the doctor’s job a lot easier.
Noise Reduction: An electronic stethoscope, most of the time, also comes along with a noise reduction feature that enables listeners to hear body sounds clearly even in a noisy environment.
Record Body Sounds: You can even connect an electronic stethoscope to an iPod or laptop to record the body sounds and hear them with accurate audio reproduction. An easy interface facility is provided for the same.
In addition, an electronic stethoscope is lightweight and has long battery life. Considering all these amazing features, surely it is a great bargain.
Exercise is good for your whole body system but especially important to strengthen your heart and lungs. Here are tips to keep your heart and lungs in top shape.
Your heart and lungs need to be put through a good workout as often as possible so they can work at optimum capacity. The heart is considered to be a muscular organ. The lungs are not muscles per se but the diaphragm is a dome-shaped muscle directly beneath the lungs that work in concert with the lungs to help you breathe in and breathe out air.
Exercise in general will serve to strengthen the heart and the lungs. Exercise forces the blood to pump through your heart at a faster pace. It also forces your lungs to inhale and exhale air more often. By so doing the diaphragm is kept very busy which stimulates the movements of the rib cage. This all leads to making your lungs stronger.
Aerobic exercises in particular are beneficial for the lungs, the heart, and the circulatory system in general. These kinds of exercises act as a learning tool to educate and train the lungs to make better use of oxygen. Your heart rate is elevated when you engage in aerobic exercise and this leads to improved cardiovascular health.
When you do an aerobic activity your heart rate increases for a time span of 20 to 25 minutes. This means the production of blood through the heart is faster. This action of the heart aids the lungs in getting healthier and stronger. This is also true for the warm-up and cool-down exercises you should include with all of your workouts.
To be fit you need a pair of healthy lungs and a strong heart. The more you can do to strengthen them both the better it will be for your overall level of health. Make aerobic exercise a part of your regular schedule.
Find an aerobic activity you like (or alternate between aerobic activities) and do it four to five times a week for no more than 20 minutes at a time. On weeks you have time for more then do more. Even if you can do something aerobically effective three times a week for the same duration of time then you’ll be benefiting your heart and lungs tremendously, not to mention your entire body!
Don’t do the same type of aerobic activity all of the time. Not only will this breed boredom but you need to do an array of exercises in order to work the different groups of muscles found throughout your body.
Aerobic exercises can also help to start your lungs down the road to healing if they have been sick or if you are recovering from an infection or illness. Some examples of aerobic activities include stretching, walking, jogging, running, swimming, jumping rope, resistance training with weights, and doing exercises in the water (otherwise known as water aerobics).
If you choose to do exercises in the water one activity that can really make your heart and lungs work harder is to stretch in the water and lift weights in the water. Remember though that everything is harder to do in water than on dry land. For that reason choose weights no heavier than five to 10 pounds. Always make sure that you are not in a pool alone when you work out in case of an emergency.
Keeping our heart and lungs in top shape is an obligation we have to our body, and apart from eating healthy foods and getting a good quota of sleep, we need to make exercise part of our daily lives as well.
If you can’t get the gym or workout at home then at least take a walk or look for opportunities to tax your body out in the yard. Look for every opportunity to work your heart and lungs – they’ll love you for it!
When looking to purchase a new stethoscope one of the big decisions you need to make is to decide if you want to purchase a single or a dual head stethoscope. There are benefits to both and this article will explore the benefits as well as the negatives of each.
Single Headed Models
If you are looking for cheap then you do not want a dual head stethoscope. You will find that single-head models are usually the cheapest options available. While they are a great extra piece of equipment and work great in a pinch, they are not what you as a doctor want to use day in and out to diagnose your patients. The reason is that this model type has a small dynamic frequency. In reviews, many complain about how hard it is to hear through a single head stethoscope.
Dual Headed Models
If you are looking for a durable and efficient model then you cannot go wrong by choosing one of the many dual-head stethoscopes that are being sold today. You will find that in reviews of this model type that they are well known for being extremely cost-effective and used frequently in emergency situations because of how fast and efficient they are at helping physicians diagnose problems.
The reason this type of stethoscope is so superior is that it has a much greater frequency response and is extremely versatile. There is no question that you can and will hear better with this type of scope than a single-headed one.
In using it the larger side is the diaphragm mode. That is what is used by the doctor to measure heart sounds that have high frequencies. In reviews, physicians have found that it is ideal for listening to the heartbeat irregularities. There is also a smaller part which is what we call the bell mode. This component is what measures lung sounds that have a much lower frequency. Medical practitioners find that it is ideal for listening to irregularities in breathing. All the doctor has to do with a dual-headed model is to rotate the head to listen to a particular body sound.
They can hear better sounds than the other types of acoustic stethoscopes plus because they are dual-headed the sound clarity is superior. This also allows you to pick up lower frequency sounds that are produced by the lungs which make this device not only good for monitoring the heart but also other parts of the bodies. In the end, this makes for a much better diagnosis.
The biggest disadvantage of using dual-head stethoscopes is that they do tend to be very pricey. That means that not only must it be maintained but it also is very expensive to replace if damaged or lost. However, it will be well worth your effort and is worth every cent in that it helps you save lives and is extremely accurate and easy to use. It is a well-known fact that dual-head single tube stethoscopes are by far superior in hearing capabilities than other types of scopes. Plus the quality used in making them is also generally higher. However, with the superior performance and quality, it also comes with a superior price.
