What is a stethoscope and how is it used?

It is generally used in the auscultation of heart sounds or respiratory sounds, although sometimes it is also used to detect intestinal sounds or murmurs due to abnormal blood flow in arteries and veins. The examination by means of the stethoscope is called auscultation.

Where is the stethoscope placed to listen to the heart?

As we have already mentioned, in order to listen to a person’s heartbeat, it is important that the stethoscope used is a diaphragm stethoscope. To do this, it should be placed on the upper left side of the chest and press gently on the skin to detect the sound of the heartbeat.

How should the stethoscope be placed?

Keep your stethoscope away from extreme heat or cold, solvents and oils. Tunable diaphragms can be removed from the chestpiece and their surfaces cleaned with alcohol or soapy water. Dry all parts before reassembly.

It is constituted by one or two rubber tubes that end in two ogives that adapt to the ear and in addition these tubes link with another one that contains a diaphragm (also called membrane) and a metal bell which amplify the auscultation sounds.

To listen to low frequency sounds, rest the stethoscope on the patient’s skin without pressing. The membrane is held by a flexible contour suspended on the membrane, allowing the membrane to vibrate widely and transmit long wavelength sounds, i.e. low frequency sounds.

To pick up the higher frequency sounds, it is pressed firmly, in the same way as would be done with a traditional double bell stethoscope in diaphragm mode. When this pressure is exerted, the membrane moves inward until it touches an inner ring. This ring restricts the movement of the membrane by blocking or attenuating the longer wavelengths of the low-frequency sounds, allowing only the shorter wavelengths of the high-frequency sounds to be heard.[8]

How is the double bell stethoscope used?

When using a double-sided Littmann stethoscope, you need to open (or point to) the side you want to use – bell or diaphragm – by turning the chestpiece. If the diaphragm is open, the bell will be closed, preventing sound from entering from the bell, and vice versa.

How do you listen with a stethoscope?

To do this, they slide the device over various parts of the chest. Normal lung sounds occur in all parts of the thoracic area; for example, above the clavicle and the lower part of the rib cage, and in the process, the physician can detect abnormal breath sounds.

Where is the stethoscope placed to listen to the lungs?

Breath sounds are best heard with a stethoscope. This is called auscultation. Normal breath sounds occur everywhere in the chest area, including above the collarbone and the lower part of the rib cage.

In this unComo article we are going to show you how a stethoscope works so that you can understand the use given to this medical device.

How do you put the stethoscope on your neck?

Place the diaphragm of the stethoscope over one of the carotid arteries. These arteries are located in the front of the patient’s neck (on both sides of the Adam’s apple).

Why do you hear better with the stethoscope?

It has a membrane and a bell. Either part can be placed on the patient. Both detect the acoustic signals that travel through the air-filled tubes and reach the ears of the explorer. The bell transmits low-frequency sounds, ideal for listening to the lungs.

How do you know if a stethoscope is good?

Put on a Littmann stethoscope (make sure the tips are pointing towards the nose). Put the tunable diaphragm on your chest with light pressure. Do you hear the heartbeat? Be aware of how loud the sound is.
