The Future Of The Stethoscope


The traditional stethoscope has been in use for approximately 200 years. One of the earliest methods of listening to heart and lung sounds was by using a rolled up piece of paper- this funneled the sound to the ear of the person performing the examination. It may seem a little basic compared to the modern 3M Littmann stethoscopes, but it led to the modern stethoscopes being developed.

With the recent introduction of the electronic stethoscopes, what will be next in the development of stethoscopes? Manufacturers (particularly 3M Littmann) are constantly updating their design to enable the most effective means of examination.

Whilst the manufacturers are trying to further develop the stethoscope, you may well have a possible solution in your pocket or bag. Studies have shown that the humble MP3 player is actually very competent at detecting heart and lung sounds.

By adding a microphone to the MP3 player and pressing the microphone to the chest of the patient, researchers were able to record a wide range of sounds with different patterns. The files that were recorded onto the MP3 player were then transferred to a PC and, using specialist software, were converted into frequency curves. Each of the stored sounds had a distinct signature. However, one of the limitations that was discovered is that the MP3 player had difficulty processing complicated or quiet breathing patterns (but this also happens to the human ear).

The idea of using a MP3 player to record sounds was prompted as several studies highlighted the fact that healthcare professionals were using sub standard stethoscopes when performing examinations- a horrifying thought, as potentially life threatening conditions could go undetected because the consultant was using an inadequate stethoscope.

Whilst the MP3 player has many benefits, and can allow you to store the reading for future reference, the current range of 3M Littmann Electronic stethoscopes are very similar and would prompt less concern from a patient than using a MP3 player or iPod to examine them! The 3M Littmann 4100WS stethoscope already allows you to record 7 seconds of data which can then be transferred to a PC via an infra red transmitter.

As the researchers stated, this study was only prompted by the alarming number of medical students and healthcare professionals using inadequate stethoscopes. When performing examinations and consultations, there can be no compromise with a patient.

The 3M Littmann stethoscopes are used by millions of people throughout the world, and are the market leader- they offer unrivalled acoustic quality and will help you to accurately and confidently perform examinations for many years.


The History of Littmann Stethoscopes


The 3M Littmann stethoscopes are used throughout the world, and are available in both traditional “bell” style models as well as the single sided models. We often take such superb acoustic sound quality for granted- however, who invented the Littmann stethoscope? It is such a valuable tool, that it is hard to imagine life without it….

Stethoscopes have been in use since the early 18th century. The French physician Rene Laennec created a wooden monaural stethoscope that had a large diameter base that funneled sound through a small opening. Unlike modern scopes, this early version only transmitted sound to one ear.

It wasn’t until 1843 that the first binaural (sound into both ears) stethoscope was created. This was modified until it used an ebony chestpiece with tubing made of wire that was covered in silk! The ear tips were ivory.

The early 1960’s brought about a revolution in stethoscopes. Dr David Littmann was a Harvard Medical School professor and he developed the very first model of what we now know as the 3M Littmann stethoscope. Dr Littmann was a cardiologist, so recognised the importance of a good quality stethoscope. In 1961, he described his dream stethoscope– it should have an open chestpiece to detect low pitched sound, a closed chestpiece with a plastic diaphragm to filter low pitched sounds, the tubing should be firm with a very short overall length and a spring to hold the ear tubes apart. The stethoscope should be light and convenient to carry.

This description is what we recognise as the two sided chestpiece stethoscope and was unlike any other stethoscopes available at the time. The 3M Littmann Classic II SE is very similar to this early model.

Dr Littmann founded a company called Cardiosonics, Inc which was based in Cambridge, Massachusetts. The firm produced two stethoscopes– the doctors stethoscope and the nurses stethoscope.

3M recognized the superb acoustic quality of Dr Littmann‘s stethoscopes and aquired the company in 1967. Dr Littmann then began to work for 3M in an advisory role. The combination of funding from 3M and the skill of Dr Littmann would change the future of stethoscopes.

Between 1967 and 1970, the Littmann range had expanded to 10 models. The tubing color was limited to gray and black, but tubing length was now available in 22″ or 28″.

By the mid 1970’s, six major lines featuring a total of 40 models were available.

The late 1970’s saw the introduction of the 3M Littmann Cardiology stethoscope. 50 of the world’s leading cardiologists were asked to design the ultimate stethoscope. The “dream” stethoscope featured dual lumen (two tubes in one) softer ear tips and a deeper bell for enhanced low frequency sounds.

Continued R & D investment helped to produce the 3M Littmann Master Cardiology stethoscope in 1987. This was the new top of the range stethoscope, and featured the 3M Littmann patented tunable diaphragm (it does not feature a traditional bell, and is single sided). This allowed the user to listen to both high and low frequency sounds by simply adjusting the pressure on the chestpiece- making examinations far easier.

The next stage in developing the 3M Littmann stethoscopes utilised advances in electronic sound amplification. The 3M Littmann Electronic E2000 was introduced in 1999 and the 3M Littmann Electronic E4100 was introduced in 2001. Both the electronic models featured state of the art amplification and noise filtration systems and were designed for advanced auscultation.

The 3M Littmann Electronic models are specially designed to detect hard to hear heart and lung sounds. The E2000 provided 14 times the amplification of a traditional 3M Littmann stethoscope, whilst the E4100 provided 18 times the amplification. The current models are the 3M Littmann Electronic 3000 and 3M Littmann Electronic 4100ws. [raw]

How To Measure Blood Pressure


It is very important to keep track of your blood pressure. Untreated and undiagnosed high blood pressure can be lead to long term health problems- that may even be fatal. There are a number of devices that can be used to measure blood pressure, although some do need a certain level of training and experience.

Automatic/Digital Blood Pressure Monitor

For the home user without any medical training or experience, an automatic/digital blood pressure monitor will probably be the easiest and most efficient method of recording your blood pressure. The automatic/digital devices can be used on either your wrist or upper arm. For simple guidance:

How do I use a digital monitor?

  1. Put the cuff around the arm or wrist (depening on the model). Turn the power on, and start the machine.
  2. The cuff will inflate by itself with a push of a button on the automatic models. After the cuff is inflated, the automatic mechanism will slowly reduce the cuff pressure.
  3. Look at the display window to see your blood pressure reading. The machine will show your systolic and diastolic blood pressures on the screen.Many digital devices have a memory to store the reading.
  4. If you want to repeat the measurement, wait 2 to 3 minutes before reinflating the cuff.

Manual/Aneroid Blood Pressure Monitor The manual/aneroid blood pressure monitors are more commonly used by health care professionals. This is because, unlike the automatic models, they do not give the results on an electronic display. The manual/aneroid model features a cuff with a inflation bulb and a dial guage. For simple guidance:

How do I use an aneroid monitor?

  1. Put the stethoscope ear pieces into your ears, with the ear pieces facing forward.
  2. Place the stethoscope disk on the inner side of the crease of your elbow.
  3. Rapidly inflate the cuff by squeezing the rubber bulb to 30 to 40 points higher than your last systolic reading. Inflate the cuff rapidly, not just a little at a time. Inflating the cuff too slowly will cause a false reading.
  4. Slightly loosen the valve and slowly let some air out of the cuff. Deflate the cuff by 2 to 3 millimeters per second. If you loosen the valve too much, you won’t be able to determine your blood pressure.
  5. As you let the air out of the cuff, you will begin to hear your heartbeat. Listen carefully for the first sound. Check the blood pressure reading by looking at the pointer on the dial. This number will be your systolic pressure.
  6. Continue to deflate the cuff. Listen to your heartbeat. You will hear your heartbeat stop at some point. The number on the dial is your diastolic pressure.
  7. Write down your blood pressure, putting the systolic pressure before the diastolic pressure (for example, 130/90).

(The above instructions are for guidance only- please consult a health care professional if you have any concerns or questions) Only a trained health care professional can diagnose high blood pressure. If you readings seem high or are causing you any concern, please contact your doctor.


What Is Blood Pressure?


When you get to a “certain” age, all you ever hear people talk about is “blood pressure”? Your friends talk about it, your doctor talks about it, they even talk about it on Oprah…

What is blood pressure, and why is it so important?

Blood pressure is the force of your blood against the walls of arteries in your heart. Blood pressure is recorded as two numbers—the systolic pressure (as the heart beats) over the diastolic pressure (as the heart relaxes between beats). The measurement is written one above or before the other, with the systolic number on top and the diastolic number on the bottom. For example, a blood pressure measurement of 130/90 mmHg (millimeters of mercury) is expressed verbally as “130 over 90.”

High blood pressure is very common in the modern world due to many reasons, and your weight, stress and diet can help to increase your blood pressure. It is estimated that 20% (or 50 million) of American citizens suffer from high blood pressure. As you get older, the likelihood of suffering with high blood pressure increases.

Long term high blood pressure can damage the arteries of your heart, making them stiff and hard. Cholesterol then clings to the damaged walls, thus narrowing them- which restricts the blood flow through your heart. Which is a VERY bad thing. Your heart has to work harder and over time the blood flowing through your body will decrease- increasing the chances of a heart attack.

High blood pressure can be very bad for you. However, like giving up smoking or losing weight, you can take steps to limit the damage caused. If you have high blood pressure, you should consider the following:

  • Don’t smoke cigarettes or use any tobacco product.
  • Lose weight if you’re overweight.
  • Exercise regularly.
  • Eat a healthy diet that includes lots of fruits and vegetables and is low in fat.
  • Limit your sodium (salt), alcohol and caffeine intake.

What color tubing?


“What color did you get?”

When you tell your friends and colleagues that you have got a new stethoscope, this will probably be the first question that they ask you- even before which model you decided to buy!

It is always a difficult choice as you will be using your stethoscope for many years (particulary as the Cardiology range are supplied with at least a 5 year warranty) and the color of the tubing can reflect your personality.

Different color tubing is great- it allows everyone a choice. For example, the Littmann pediatric range of stethoscopes is supplied in caribbean blue, navy blue, pine green as well as raspberry and red. These colours are great when working with kids, as it makes you appear friendlier and less scary!

The Cardiology range of the Littmann stethoscopes are currently supplied in the more traditional colors- black, navy, burgundy etc, but they are beginning to get more diverse in color choices. The All Black is popular as it is traditional but with a modern twist and the chocolate and hunter green increase your options.

Whatever color you choose to buy, the most important thing is that with a Littmann stethoscope you know that you are buying the best possible stethoscope- an invaluable tool to help with the diagnosis of patients.


Medicine and the Global Economy


Everyone is aware of the effects of the global economic problems. People are losing their jobs, homes are being repossessed, prices are increasing. It is well documented and widely reported in the media. It is causing problems for everybody- how will this affect the medical industry?

As finances become strained, people will start to look at ways of saving money. Non essential items may be reconsidered, but what if people look to save money by cancelling their health insurance (or their employer goes bust and no longer provides health insurance?) If this happens, there will be less money available in the medical industry.

Less money will mean that cut backs may happen. Health care professionals may face redundancy, and there will be less investment in new resources. However, people will still continue to require treatment- whether they have health insurance or not. It is a worrying prospect, but hopefully will not happen. If it does, the US Government may be required to provide some form of free medical treatment- another burden on taxpayers in already difficult times.

The recent G20 summit in London, UK will hopefully help to minimise the effects of the global economic slowdown. The world leaders appreciate the importance of working to help resolve the situation and to therefore minimise any further problems. However, whatever happens as result of the G20 meeting, the world leaders are not magicians and the what happens next will be a concern for everyone.
