Stethoscope - Wikipedia, the free encyclopedia

The stethoscope is an acoustic medical device for auscultation, or listening to the internal sounds of an animal or human body. It typically has a small disc-shaped resonator that is placed against the chest, and two tubes connected to earpieces. It is often used to listen to lung and heart sounds. It is also used to listen to intestines and blood flow in arteries and veins. In combination with a sphygmomanometer, it is commonly used for measurements of blood pressure. Less commonly, "mechanic's stethoscopes" are used to listen to internal sounds made by machines, such as diagnosing a malfunctioning automobile engine by listening to the sounds of its internal parts. Stethoscopes can also be used to check scientific vacuum chambers for leaks, and for various other small-scale acoustic monitoring tasks. A stethoscope that intensifies auscultatory sounds is called phonendoscope.

A pregnant woman with anaemia and thrombocytopenia

A 28 year old woman who was 31 weeks pregnant attended the emergency department of our hospital with acute onset of abdominal pain in her right upper quadrant. She had undergone regular antenatal check-ups in the midwifery clinic, with no problems reported. She had no medical history of note and was not taking any drugs. She was a non-smoker and before she was pregnant she rarely drank alcohol. Her cardiovascular, respiratory, and neurological examinations were unremarkable and she had no peripheral oedema. The fetal heart sounds were normal. Her blood pressure was high (136/104 mm Hg) and her pulse was 88 beats/min. The urine protein to creatinine ratio showed no evidence of proteinuria.

The Auscultation Assistant - Physiology

     Before trying to decipher what may be the underlying cause of a murmur, it is important to first understand what the normal heart sounds are, and what normal variations of these sounds may occur. It is assumed that you already understand the anatomy of the heart, and have read a basic physical examination textbook which describes the standard methods for auscultation.
