Can you remove the bell of a stethoscope?
To remove, pull firmly on the eartip. On Littmann stethoscopes with traditional combination chestpieces, it is necessary to open the side of the chestpiece being used. This is accomplished by holding the chestpiece stem in one hand and rotating the chestpiece with the other hand until a click is felt.
Will a stethoscope work without a diaphragm?
While other stethoscope brands require unscrewing and changing diaphragms and bells, Littmann stethoscopes are all about ease and simplicity. To hear low-frequency sounds, rest the chestpiece lightly on the patient. In this position, the diaphragm membrane is suspended, allowing it to resonate low-frequency sounds.
Do you use bell or diaphragm for heart sounds?
The bell of the stethoscope is better for detecting lower-frequency sounds whilst the diaphragm is better for higher frequencies. The bell is usually used to listen to the mitral valve and the diaphragm at all other sites. Heart auscultation is usually performed with the patient sitting up or reclined at about 45°.
What stethoscope do paramedics use?
The two models of stethoscope that we recommend to clients in the pre-hospital care setting, depending on their skill level and scope of practice, are the Littmann Lightweight II Stethoscope and the Littmann Classic III range (formerly the popular Littmann Classic II line).
At what rate should you deflate the BP cuff?
The AHA recommends that the cuff be inflated to at least 30 mm Hg above the point at which the radial pulse disappears. The cuff should then be deflated at a rate of 2 to 3 mm Hg per second (or per pulse when the heart rate is slow).
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.”
