Doppler Stethoscope
Acoustic stethoscope: this is the most commonly used type of stethoscope. It transmits sounds from the chest and back to the doctor's ears through hollow tubes filled with air. It consists of a bell and a diaphragm. The diaphragm is placed on the patient's chest, and the vibration of the plastic diaphragm produces acoustic sound waves which are transmitted through the tube to the listener's ears. Electronic stethoscopes: although electronic stethoscopes have more complex systems, they are more efficient stethoscopes. Electronic stethoscopes provide interpreted data, making it easier for inexperienced users. Doppler stethoscope: this is a type of stethoscope that works with the Doppler effect. Movement is detected by a change in the frequency of sound waves. It is sensitive in detecting aortic insufficiency or impaired ventricular relaxation. Fetal Stethoscope: it is placed on the abdomen of pregnant women and used to listen to the baby's heartbeat.
