Study Notes
Stethoscope Bell Purpose
- The bell amplifies low-frequency sounds, allowing for clearer auscultation of sounds like murmurs and bruits.
Using the Diaphragm
- The diaphragm is used for amplifying high-frequency sounds, such as normal heart sounds, lung sounds, and bowel sounds.
Stethoscope Tubing Length
- The recommended tubing length is 18-22 inches, this allows for proper sound transmission without excessive attenuation.
Earpiece Fit
- Comfortable and firm fit in the ears prevents sound leakage and improves sound clarity during auscultation.
Analyzing Mitral Stenosis Murmur
- The bell is used to analyze the mid-diastolic murmur of mitral stenosis, because this type of murmur is typically low-frequency.
