Reviews are important in that they allow you to read other individuals experiences with particular stethoscopes. The vast majority on the market today aren’t new, and so have a track record that quickly allows an individual to determine how good they are. The only ones that are continually evolving are the electronic versions. Because of advances in technology, they will continue to improve over time. If you haven’t used an electric stethoscope, you will be amazed at the difference in sound quality from a traditional acoustic stethoscope. These are the wave of the future for stethoscopes, and will only become more prevalent in the healthcare setting as the prices continue to drop. stethoscope prices

Korotkoff Sounds- Determining What To Listen For When Taking A Blood Pressure
The Korotkoff sounds are what is used to determine blood pressure in a patient when taking the pressure manually. These sounds are due to the opening and closing of the hearts valves. When a blood pressure cuff is placed around the upper arm and pumped up or inflated to a pressure that exceeds the arterial pressure, no sound will be heard from the brachial artery because there isn’t any blood flow. When pressure is released from the cuff to the point of being equal with the systolic pressure of the heart, some blood leaks through, and the sound this makes is the first of the Korotkoff sounds, which is similar to the sound of tapping or clicking heard with your stethoscope.
When this first Korotkoff sound is detected that is the systolic pressure reading. As you continue to release the pressure in the blood pressure cuff, you will continue to hear a thumping. This thumping continues to be audible while the pressure is between the systolic and diastolic heart pressures, and this is the second of the Korotkoff sounds, and these sounds occupy most of what you will hear between the systolic and diastolic regions.
Without getting too bogged down in technical science, suffice it to say that the third and fourth Korotkoff sounds are heard just before the fifth Korotkoff sound. Korotkoff sounds 3 and 4 are unnecessary when determining blood pressure, and sometimes very difficult to detect. The 2nd Korotkoff sound is also irrelevant to a degree when determining blood pressures, more on that in a minute.
It used to be that the standard for determining a blood pressure was to detect the first and fourth Korotkoff sounds. This is no longer the case as standards have evolved. The current teaching standard for determining a patients blood pressure is to listen for only the 1st and 5th Korotkoff sounds.
As described earlier the first sound you will hear is the clicking or tapping sound you first detect when lowering the cuff pressure to the hearts systolic level (This is the systolic blood pressure). The fifth and Final Korotkoff sound is not a sound at all. It is the point at which no sounds are no longer heard through your stethoscope. The current standard states that the diastolic pressure is 2mm of mercury ABOVE the last sound detected. This may seem confusing if this is your first time learning about these sounds, but with practice, they become second nature.
How To Use A Stethoscope
Learning how to use a stethoscope isn’t too difficult. The difficulty lies in the interpretation of whatever bodily sounds you are listening to, whether they are heart, lung, or even bowel sounds. This simply takes time and practice. reviewallnew.com
Before using your stethoscope, clean off the earpieces with an alcohol swab.You would need to warm the chest piece of the stethoscope by holding it in your palm for about 30 seconds. This step is unnecessary if you have a Littmann stethoscope with a non-chill rim.
Once you have the earpieces comfortably in the ear canals, tap the diaphragm very gently with your fingertip to see if the chest piece is indexed. If it is a dual head chest piece you will know if it is indexed when you clearly hear the tap of your finger against which ever side you are wanting to use, either the bell or diaphragm side. If you don’t hear your finger tapping then rotate the chest piece until it clicks.
Place the chest piece firmly to the skin by holding it between your index and middle fingers. Avoid unnecessary noises by making sure the chest piece is firmly in place and that the tubing isn’t touching anything. Simply place the diaphragm or bell directly above the part of the body you wish to listen to, or auscultate.
When not in use it is better to store your stethoscope by letting it hang from the headset to avoid kinking the tubing. This is obviously a brief guide on how to use a stethoscope. For a much more in depth guide on how to use a stethoscope go here.
