Auscultation is usually performed by listening through a stethoscope. Health care providers routinely listen to a patient's lungs, heart, and intestines to evaluate the frequency, intensity, duration, number, and quality of sounds. Health care providers also use auscultation to listen to the heart sounds of unborn infants. This is not performed with a stethoscope, but with sound waves. This is called a Doppler ultrasound. It can also be used to hear pulses in the hands and feet. Related topics: |
