Guide: The Best Stethoscope for the Job
It might be hard for your family and friends to understand that there is more to the venerable stethoscope than “playing doctor.” While the basic goal with each stethoscope is the same, listening to the heart and lungs, the means and details of that listening vary from job to job. There is one more variable that matters even more. It’s what you think about the right stethoscope for your practice. This blog can say which stethoscope should be the one you must have, but when it’s your instrument to use, it’s you who must be content with your decision. You may feel that your veterinary practice mandates you use a cardiologist’s stethoscope, so be it. This is merely a guide created by a company that has been putting stethoscopes in the hands of medical professionals for decades. All that experience still doesn’t make us the end-all-be-all for your specific needs. That stated this guide is an ideal place to start your investigation. One more note... Before you skip ahead to the section that best serves your purposes. The answer to the unasked question (which is the best brand?), is Littmann. They are the best all-around stethoscope manufacturers the world-round. While there is some stiff competition across the board from companies we admire greatly like Prestige, Spirit or Welch Allyn, and from many who make quality stethoscopes themselves, Littmann wins accolades more often in more categories, hands down. Best stethoscope for nurses There’s a good reason we spend a lot of time on our nurses at Medshop. It's true that they are the hard-working bread and butter of our business, but they are also the ones putting us all back together when something goes awry… and something will always go awry. For nurses, the choice is simple. The Classic III from Littmann is the best all-around stethoscope for most nurses. It’s the Toyota Hilux of stethoscopes, meeting the most needs in one package, but also taking the most abuse and still cleaning up like new. Not to be confused with the Cardiology III, a slightly different instrument tuned more for detailed observation, the Classic III offers the same duel head advantage. With the Classic III, you'll hear high and low frequency sounds without having to carry two tools, without fumbling around. For nurses, who are juggling about five-million tasks, this reliability is priceless. In fact, nurses aren't alone in appreciating the security of the Classic III as we'll find in just a second. Best stethoscope for doctors While the aforementioned Cardiology III might do the trick for many doctors, the unbeatable standard for doctors is the one used by cardiologists: Littmann’s Cardiology IV. In fact, categorically, this section is probably the most wasted “ink” in this blog as most doctors and cardiologists know this without needing to do research. They aren’t reading this blog because the reputation of the Cardiology IV procedes itself. Best stethoscope for medical students Alright, so this is the category where picking the best gets a little shakier than the first two sections above. In that spectrum between the ideal stethoscope on paper and one's personal preferences, two options fall somewhere in the comfortable middle. Littmann’s Classic III will work perfectly for any student as an initial investment, but the Cardiology IV will get the job done well for a long time. Consider the Cardiology IV if you’re not on a tight budget or if you can’t get that wealthy relative to chip in for your future. Of course, as students often don't have large budgets so the classic III makes a worthy choice. Best stethoscope for paramedics For the medical professionals who aren’t happy savings lives unless there is a street race involved (kidding, kidding, kidding… sort of) the Classic III is the way to go. Paramedics won’t necessarily benefit from the precision of Cardio IV to warrant that level of exactness, even though it’s a tough enough tool to do the job. The Classic III is the best option for ambulance drivers for all the same reasons it’s the best option for nurses. It’s versatile, tough, and accurate. The stainless steel chest piece of the Classic III means it will not only take being dropped with a shrug, but it will clean up with little effort. Littmann didn’t skimp on comfort with this workhorse either. Users love them for the snap-tight ear tips, which are not only a snug seal but a comfy fit too. Best paediatric stethoscope What then, is the right stethoscope for the smallest and most valuable patients among us? There’s no question that Littmann rules this blog, and this category is no exception. The Classic II Paediatric does the job just fine. It’s the same technology as the normal Classic II, but the Paediatric version is a little smaller to accommodate small chests. As such, it’s a two-bell instrument, with a non-chill rim on the smallest size for all the obvious reasons. (See end of the previous section if you're confused.) It’s possible to find other stethoscopes which do some of the things the II Paediatric does, but none that do it all in one package. If this blog didn't address your specific needs, please don't hesitate to contact us for advice. We're all about getting you in the right stethoscope. It saves us both potential stress in the long run. One more thing... For those readers who have friends and family that are the fancy gift-giving sort, this is the perfect time to share this blog with them. You never know when someone is going to get that gift-giving spirit so you always want to make sure they are empowered with all your hopes and dreams. It might also be a good idea to remind said family and friends of your favourite colours too… just in case. Author: Steven John Cumper, B.App.SC.

How To Use A Stethoscope Effectively: Comprehensive Guide
Learn the art of proper stethoscope usage, identifying normal and abnormal sounds, and discovering the essential techniques for accurate assessment. How to Use a Stethoscope: A Step-by-Step Guide The stethoscope is one of the most important tools in your medical bag, and knowing how to use it effectively is paramount to your success as a medical professional. You will use your stethoscope to measure blood pressure, listen for heart sounds and bruits, zero in on lung sounds, From initial auscultation to thorough diagnosis, the proper utilization of your stethoscope will serve you and your patients well. We have gathered some tips to help you get started. Choosing the Right Stethoscope There are many types of stethoscopes, and choosing the right one depends on your needs. For example, cardiologists and pediatricians use different types of stethoscopes that work best for their patients. There are countless brands to consider, each offering different features. Some of the brands we carry even have customization options. Stethoscope types include: Classic: a general, multipurpose stethoscope like this one that is designed to meet the needs of most medical professionals. Cardiology: best used to identify heart sounds and minimize background noise. Pediatric: specifically made with children in mind, these are perfect for small pediatric patients. Digital: a newer technology, digital stethoscopes connect to smartphone apps that help with noise cancellation, increased amplification, and easier identification. They are a pricier option with advanced features. Teaching: these stethoscopes come with two headsets to allow teachers and students to listen together. Lightweight: perfect for EMTs and nurses, lightweight stethoscopes are a great option for quick auscultation. Veterinary: animals have varied body shapes that are different to humans, so veterinary stethoscopes are shaped in a way that allows access to the areas a veterinarian needs to reach. Adjusting a Stethoscope Let’s dive into adjusting your stethoscope. You need a good fit to provide accurate results. To make sure your stethoscope is appropriately adjusted: Make sure the ear tips are sized and fitted correctly: The size of your ear tips will make a difference in overall sound quality. With improperly fitted ear tips, the acoustics will be distorted, rendering the stethoscope ineffective for listening. You can purchase ear tips in a large range of sizes to suit your needs. If you are experiencing pain in your ears after wearing your stethoscope, the ear tips are too big. If you cannot get a proper seal in your ears and can hear a lot of background noise, the ear tips may be too small. Adjust the headset tension: We know how uncomfortable a stethoscope can feel when it’s fresh out of the box. With a few minor adjustments, your device will start to feel natural. If your headset is too tight, you could experience pain in the ears, or even headaches. A headset that is too loose will result in no sound coming through. Adjusting the tension in the headset is a quick and easy process. Increasing and decreasing the tension is done by pulling apart or pushing together the ear tubes. After adjustment, the tubes will hold their shape, ensuring a proper fit. How to Wear a Stethoscope Correctly How you wear your stethoscope matters, too. Depending on what you need to listen for, the patient will need to be positioned accordingly. Ear tip placement is also important. Positioning the Patient First, ensure the exam room or area is free from excessive background noise. Then you can prepare your patient for listening based on what you need to hear. To Hear: Position the Patient: Heart and abdominal sounds Supine position Lung sounds Upright position Positioning the Ear Tips The ear tips of your stethoscope need to be facing forward to work properly, with the ear tube curve pointed behind you. They need to have a snug fit and tight seal, so if this is not achieved, you will need to purchase a different size. You will be able to feel the difference and adjust as necessary. Choosing the Right Chest Piece You may be able to swap out the chest piece. If your stethoscope has this option, make sure the chest piece is right for your patient. Chest pieces are available for cardiology, pediatrics, and other specialties that may suit your specific needs. How to Use a Stethoscope: 5 Ways to Listen to Your Patient Once you have adjusted your stethoscope and ensured a proper fit, you are ready to start listening to patients. First, holding your stethoscope correctly will make a big difference in how well it works for you. Using your index and middle fingers on your dominant hand, hold the stethoscope between the bell and diaphragm with a finger on either side. This grip will help reduce extra noise compared to placing your fingers on the diaphragm. Next, make sure you are treating the individual patient and adjust your technique to work on each patient. For example, you might hear outside sounds on a patient with body hair even if the room is quiet. This is from hair rubbing against the diaphragm. Take care to be very still to avoid this issue. If your patient is overweight, you can ask them to lean forward when listening to their heart. This may help with hearing the heart in patients with a thicker chest wall. There are five main functions of a stethoscope to be familiar with: Listening to the Heart Heart sounds are an important part of your exam. To listen to a patient’s heart, you will need to: Place the diaphragm on the patient’s chest over their heart. This is on the left side of the chest, just under the breast. Maintain a tight grip on the chest piece and push down on the patient’s chest. You want to make sure you are well connected so that you do not pick up outside sounds. For a thorough examination, make sure you listen long enough and identify normal heart sounds. You can also measure their pulse. Pay attention to anything that sounds abnormal, like a heart murmur or ventricular defect. Listening to the Lungs The lungs tell the story of the patient’s breathing quality. You can listen to the lungs to check for things like air or fluid in the lungs. Like before, you will use the diaphragm side of the chest piece to listen to the lungs. You can listen from the front of the chest or the back. Make sure to move your stethoscope around to cover the entire body of each lung. Listen to both lungs and pay attention to any differences between the two. Listen for wheezing and crackling noises as well as normal breath sounds. Listening to Abdominal Sounds When listening to the abdomen, you are checking for abnormal organ activity. This helps identify issues with the bowel and vascular disease. Use the patient’s navel as a starting point and consider that the center of the abdomen. Mentally draw a diagram on the belly, separating the area into four quadrants. Use the diaphragm to carefully listen to each section separately. Check for normal and abnormal bowel sounds. Ideally, it will sound like the stomach is “growling.” Abnormal sounds include silence (this could indicate a blockage) and fast sounds, which may indicate disease. Listening for a Bruit A bruit, or vascular murmur, is “an audible vascular sound associated with turbulent blood flow.” Bruits are often associated with blocked arteries, atherosclerosis, and murmurs. Checking for a bruit is indicated if a murmur has been identified. To check for a bruit: Locate a carotid artery in the patient’s neck. Using the diaphragm, apply light pressure. Listen for a “whooshing” sound, and take care not to confuse the sound with a murmur, as they often sound similar. Other major arteries can be used to check for bruits. Checking Blood Pressure Blood pressure is one of the easiest indicators of a patient’s cardiac health. Checking blood pressure using a stethoscope is a simple process: Snugly apply a blood pressure cuff to your patient’s arm. Ensure the patient is sitting in a relaxed position and make sure their legs are uncrossed. Use the diaphragm and place it over the brachial artery below the blood pressure cuff. Listen for Korotkoff sounds to measure the systolic blood pressure. Squeeze the bulb on the blood pressure cuff to inflate the cuff. Generally, you will inflate it to 180 mm Hg. Once the correct pressure is released, listen closely for Korotkoff sounds to determine the diastolic pressure. The systolic pressure and diastolic pressure together will indicate the patient’s blood pressure. Maintaining and Cleaning Your Stethoscope To ensure longevity and functionality, you need to properly clean and maintain your stethoscope. We have seen stethoscopes lose their effectiveness earlier than necessary due to inadequate care, so don’t skip this important step! Be sure to sterilize the stethoscope between patients. You can use regular soap and water or alcohol wipes and then air dry once cleaned. Remove the diaphragm (if your model allows) and clean it separately. Remove ear tips and swab those with soapy water or alcohol. Do not submerge the stethoscope in water, as this can destroy the inner tubes and render it useless. Conclusion You will use your stethoscope daily, so proper care and technique will make all the difference in its usefulness. These tips will help you treat patients with confidence and ensure a long life for your stethoscope. Author: Steven John Cumper, B.App.SC.

Product Feature: Littmann Cardiology IV
Introducing the latest and greatest in stethoscope technology from 3M, the Littmann Cardiology IV. A revolutionary device that despite being relatively new to the market, is already in huge demand and receiving rave reviews. The Cardiology IV sets a new standard, unmatched in its field, it is considered a pinnacle of achievement in auscultation technology. So what is all of the hype about? Let's dive in and find out. Supreme acoustics Identifying and picking up on the most subtle of sounds is a critical factor in the accurate assessment and diagnosis of patients. The engineers at 3M Littmann are dedicated to advancing the technology that enables greater levels of precision where patient assessment is concerned. This drive to innovate and exceed previous expectations has been at the forefront of the Cardiology IV design. Precisely engineered to enable barely perceptible sounds to be heard, the Cardiology IV presents a level of finesse previously unimagined. Designed for clinicians who require superior quality and exceptional versatility, the Cardiology IV provides the opportunity and ability to hear more than ever before. Exceptional versatility Despite the name, the Cardiology IV isn't just a stethoscope for cardiologists. Designed with precision and versatility in mind, the Cardiology IV is an ideal choice for any medical practitioner who wants to know they can provide their patients with the best of care, using the best technology available. It can be used to accurately study and listen to, lung, cardiac, arterial and other bodily sounds with both adult and paediatric patients. The Cardiology IV is used by medical specialists, general practitioners, paramedics, critical care nurses and students to name a few. The level of sound quality and precision also means that hearing affected users may benefit from the increased clarity and range of frequencies that the Cardiology IV offers. Elegant design The design for the Cardiology IV resembles a somewhat streamlined and refined version of the Cardiology III. The distinctive chalice shaped chest piece features the much desired tunable diaphragms on both the large and small sides to deliver exceptional acoustic performance and diagnostic ability. Many people prefer to use the paediatric / small side of the chest piece as a traditional open bell. This is easily achieved by removing the tunable diaphragm and replacing it with the nonchill bell sleeve that is provided with all Cardiology IV stethoscopes. Available with a range of classic tubing colours, the Cardiology IV exudes elegance and high performance simultaneously. Outstanding features One of the key features of the Cardiology IV stethoscope is the Littmann patented next generation tubing. It's designed to be more durable and last longer than any stethoscope tubing before it. The tubing is stain and damage resistant and not made from natural rubber latex or cheap and nasty phythalate plasticisers, to prevent allergic reactions and skin irritation. Construction is another highlight of Littmann's ingenuity, the dual-lumen tubing design creates two sound paths in one tube to eliminate the rubbing noise generated by traditional double tube designs. For maximum comfort and the perfect fit the headset is easily adjustable and the ear tips are designed to fit gently yet securely in the ears. Worthy investment Given all the benefits of the Littmann Cardiology IV stethoscope, it is understandable that it comes with a price tag that reflects this prestige. Consider this, however, there are many Littmann stethoscope users have kept their stethoscopes for 10+ years. When you break the cost down over this kind of timeline it is definitely a worthwhile investment. Plus the added security and peace of mind that you get from knowing that you are using the very best that stethoscope technology has to offer. To top that off, Littmann offers a 7-year warranty for Cardiology IV stethoscopes that covers all parts of the stethoscope for wear and tear plus incidental damage. The Cardiology IV presents and offer that is too good to ignore. All Littmann Cardiology IV stethoscopes purchased from Medshop Australia come with a free LED penlight and free laser engraving.
