What are the different sides of the stethoscope for?
A Bell and Diaphragm The stethoscope has two different heads to receive sound, the bell and the diaphragm. The bell is used to detect low-frequency sounds and the diaphragm to detect high-frequency sounds.
What is the stem of a stethoscope?
The stem connects the stethoscope tubing to the chestpiece. On Littmann stethoscopes with two-sided chestpieces, the stem is used to index, or open, the side of the chestpiece that you wish to use.
How many pieces does a stethoscope have?

What is the bell of a stethoscope?
Many stethoscopes have a separate bell and diaphragm. The bell is most effective at transmitting lower frequency sounds, while the diaphragm is most effective at transmitting higher frequency sounds. Some stethoscopes combine these functions into a single surface.
What side of the stethoscope do you use for bowel sounds?
Place the diaphragm of your stethoscope lightly over the right lower quadrant and listen for bowel sounds. If you don’t hear any, continue listening for 5 minutes within that quadrant. Then, listen to the right upper quadrant, the left upper quadrant, and the left lower quadrant.
What is the most important part of a stethoscope?
The chestpiece or head of the stethoscope is the central part of the entire device. The chestpiece is an essential part of a stethoscope’s acoustic performance. It is responsible for detecting, capturing, and transferring sounds from the body to the headset.
How can you tell the difference between S1 and S2 heart sounds?
Related to the closure of the mitral and tricuspid valves. Loudest at the apex….1. Auscultate the heart at various sites.
| S1 | S2 |
|---|---|
| Just precedes carotid pulse | Follows carotid pulse |
| Louder at apex | Louder at base |
| Lower pitch and longer than S2 | Higher pitch and shorter than S2 |
| Because systole is shorter than diastole: |
What is the difference between the bell and diaphragm?
How do you switch between bell and diaphragm?
The most important parts to know are the diaphragm, which is larger, flatter side of the chest piece, and the bell, which has the smaller, concave piece with a hole in it. Switch between the two by twisting the chest piece 180 degrees. You’ll hear a click. Then tap each side to see which one is “on.”
How do you remember bell or diaphragm?
Bell. The diaphragm is best for higher pitched sounds, like breath sounds and normal heart sounds. The bell is best for detecting lower pitch sounds, like some heart murmurs, and some bowel sounds.
What are the two types of stethoscope chest pieces?
They can be divided into two main types: mechanical and electronic.
What are the different types of stethoscopes?
The different types of stethoscopes and their uses are described below; An acoustic stethoscope is unpowered and has three main components that aid its functions. These are the chest piece, tubing, and earpieces. The chest piece consists of a bell which transmits low-frequency sounds, and a diaphragm which transmits high-frequency sounds.

What is a chest piece on a stethoscope?
The chest piece is the star of the show, as it is the part of the stethoscope that touches the patient and captures the sound leading to the auscultation portion of the exam! The chest piece comes in a few different styles: Two-sided chest piece with one diaphragm and one (closed) bell.
What is the bell side of a stethoscope used for?
This part of a stethoscope helps EMT to respond to a larger portion of patients’ body by picking up higher frequency noises as compare to the chest piece half of the bell in case of emergency. The bell side is small as compared to the diaphragm side.
