Medical Definition of eardrum eardrum: A hollow, drum-like sound produced when a gas chamber is heavily emptied. An eardrum may be felt when the chest contains free air (pneumothorax) or when the stomach is swollen with gas. Also known as tympanitis.
Tympanic noises that may be heard on air-filled structures during an abdominal exam. Hyperreonation (pneumothorax) would be similar to beating swollen cheeks. Normal resonance / resonant sound created by beating a normal chest.
The eardrum can usually be felt above the abdomen, but it is not a normal chest murmur. The sounds of the tympanic membrane that can be heard in the chest indicate excess air in the chest, which can occur with a pneumothorax.
There are three main sounds of medical percussion: resonance (heard by the lungs), eardrum (heard by the air-filled loops of the intestine) and lethargy (heard by liquid or solid organs). The presence of large areas of lethargy should lead to an assessment of the organomegaly, intra-abdominal mass, or fluid.
The eardrum is a loud musical sound that indicates a cavity in the stomach or intestines filled with air or gas. Sleepiness indicates fluid or underlying organs such as the liver and spleen.
Tympanitis is a condition where excess gas builds up in the gastrointestinal tract and causes gas. The term derives from the Greek τύμπανο, drum.
Percussion means caressing the stomach and listening to noises. When a doctor touches just below the chest, he can hear the sounds of a normal liver. Similar noises you hear when you hit farther than the liver should be can be a sign of an enlarged liver.
By pressing on the stomach, you can know if your internal organs are of normal size, if something is hurting you and if something unusual is going on. Seeing, hearing and feeling are part of a physical exam.
A protruding belly is a condition where the belly protrudes more than normal. This could be due to excess subcutaneous fat, loss of muscle tone, or accumulation of substances in the stomach that cause it to swell. Muscle tone may be low due to inactivity or a medical problem such as low blood pressure.
During the abdominal exam, note the general shape of the abdomen and describe it as flat, scaphoid, bulging, or distant. Note the presence of curved sides or focal protuberances.
The doctor will also perform a maneuver called angled percussion, which involves lightly tapping the area of the back where the kidneys are located. This maneuver destroys all the inflamed tissues around the kidneys and causes pain if you have a kidney infection.
The intestine is hollow, so intestinal sounds resonate in the stomach, just like the sounds in water pipes. This problem can cause gas, fluid and intestinal contents to accumulate and rupture (rupture) in the intestinal wall. Your doctor may not be able to hear bowel sounds when he listens to your stomach.
Murphy’s mark. Murphy’s sign is a held breath evoked by gently pressing the upper right quadrant which prompts the patient to take a deep breath. From: Blumgart’s Liver, Pancreas and Biliary Tract Surgery (5th Edition), 2012.
One technique for assessing ascites is to assess repositioning lethargy. In the stomach of ascites, the gas-filled intestinal loops flow upward, while the liquid of the ascites falls into the dependent part of the stomach. As a result, percussion noises are muffled tympanically on the intestinal loops and surrounding fluid.
Percussion: the percussion technique is the same as for lung examination. Tympanic (drum-like) sounds produced by percussion on air-filled structures. Dull noises that occur when a solid (e.g. liver) or fluid (e.g. ascites) structure lies below the area to be examined.
Objective. The purpose of the abdominal examination is to obtain more information that can give an indication of the cause of the patient’s symptoms. The doctor receives information through inspection, auscultation, palpation and pat on the stomach.
Tympanum: A hollow, drum-like sound produced when a gas cave is severely emptied. An eardrum may be felt when there is free air in the chest (pneumothorax) or when the stomach is swollen with gas.
