How Does Stethoscope Work

What is a stethoscope?

A stethoscope is a medical device to listen to sounds within the human body. At one end has a diaphragm, a vibrating membrane designed to capture sounds. The diaphragm is connected to a hollow tube filled with air. The tube is divided into two and ends at the headset using the doctor. The stethoscope can be placed on the patient's chest to listen to your breathing or heart rate, or the underbelly to hear the intestines as personal care.

The doctor holds medical stethoscope on the patient's body, usually to listen to the breathing or heart rate. When the heart beats or lungs fill with air, small sound vibrations occur throughout the body. Stethoscope picks up these vibrations and amplifies the diaphragm. The sound passes through the tube, and then transferred him to headphones doctor. There are also electric stethoscopes, using a type of microphone to capture and amplify sound. However, because these may lose or distort parts of the sound, most doctors use the acoustic version.

Stethoscopes are often used to listen to heart. A healthy heart produces a double beat with little or no noise. These are the sounds of the heart valves that close. With a stethoscope, a doctor can detect a breath: a whistling sound after the heartbeat sometimes can indicate serious heart problems. The exact sound of the blow can give the doctor signals about what is causing it. A stethoscope is also used to detect problems with the lungs. The doctor makes the patient can breathe deeply and hear strange sounds. Also hit the patient's chest near the stethoscope and hear the sound. A healthy lung sounds empty, while not one filled with fluid. A stethoscope can help the doctor detect lung problems such as asthma, pneumonia and bronchitis.
