Frequently Asked Questions (FAQs)
1. What are the 5 major parts of a stethoscope?
The five major parts of a stethoscope are the chestpiece (head or diaphragm), tubing, earpieces, binaural, and stem or yoke. Each part plays a crucial role in transmitting and capturing body sounds for medical examination.
2. Do you use bell or diaphragm for blood pressure?
Although both the bell and diaphragm can be used to measure blood pressure, the bell is generally better at picking up low-pitch vascular sounds, such as the Korotkoff sounds. Therefore, using the bell is recommended for blood pressure measurements.
3. Do you use bell or diaphragm for lung sounds?
For lung sounds, the diaphragm is more suitable as it is designed to capture higher-pitched sounds like breath sounds and normal heart sounds. On the other hand, the bell is more effective in detecting lower-pitched sounds like certain heart murmurs and bowel sounds.
