Quizplus · Accepted Answer

The bell of the stethoscope is used to hear soft, low-pitched sounds such as extra heart sounds or vascular sounds (bruit). Pulse oximetry is a noninvasive measurement of arterial oxygen saturation in the blood. The diaphragm is used to hear high-pitched sounds such as breath sounds, bowel sounds, and normal heart sounds. A Doppler ultrasound probe is used to detect difficult-to-hear vascular sounds such as fetal heart tones or peripheral pulses.
