I proceeded the way I do all my physical exams: I start with the eyes, ears and mouth and methodically work my way south — checking the lymph nodes and thyroid of the neck, listening to the heart and the lungs, percussing the abdomen, all the way down to feeling the pulses near the big toe.

When percussing boney areas such as the clavicle, the pleximeter can be omitted and the bone is tapped directly such as when percussing an apical cavitary lung lesion typical of TB.Owen Epstein, G. David Perkin, John Cookson, David P. de Bono. Pocket Guide to Clinical Examination, Third Edition. Mosby, 2004. There are two types of percussion: direct, which uses only one or two fingers, and indirect, which uses the middle/flexor finger.

The purpose of the abdominal exam is to get more information that could indicate what is causing the patient's symptoms. The physician gains information by inspecting, auscultating, palpating, and percussing the abdomen.

Multiple variations on the exam also exist including different stethoscope placements such as over the costal margin or liver, percussing the abdomen instead of scratching, or scratching in different patterns i.e. circular or lateral directions.

This involves a process of percussing the stone with a hard hammer such as a stone, a soft hammer such as a bone or antler, and pressure flaking using a punch made of bone or antler. Unsurprisingly, Acheulean tools such as ficrons can be found in the rift valley of Kenya, K. Kris Hirst. "Lower Paleolithic (Early Stone Age)." About.

Since indirect percussion can be so precisely placed, the platform is often much smaller on flakes produced in this way than in other methods of flake removal. Of course, indirect percussion requires two hands to hold the percussing tool set. One holds the hammer, and one holds the punch. Therefore, modern hobbyists must use a third object in order to hold the targeted piece of tool stone while they strike it.

3DiTeams learner is percussing the patient's chest in virtual field hospital Simulators have been proposed as an ideal tool for assessment of students for clinical skills. For patients, "cybertherapy" can be used for sessions simulating traumatic experiences, from fear of heights to social anxiety. Programmed patients and simulated clinical situations, including mock disaster drills, have been used extensively for education and evaluation. These "lifelike" simulations are expensive, and lack reproducibility.

His commentary on Auenbrugger's original text extended its length four times. This method of percussion had a resurgence under Corvisart's translation and became an intrinsic aspect of clinical medicine. In particular, Corvisart attentively focused on the heart and lungs as sources of lesions. His studies with these lesions led to him percussing the chest of his patients to find such wounds inside the body, studying the "organic diseases of the heart".

In medicine, shifting dullness refers to a sign elicited on physical examination for ascites (fluid in the peritoneal cavity).Murray Longmore, Ian B. Wilinson, Edward H. Dawvidson, Alexander Foulkes and Ahmad R. Mafi Oxford Handbook of Clinical Medicine 8thEdition Oxford University Press 2010 The two steps of shifting dullness. Percussion of the green section shifts from a dull note to a tympanic note after the patient changes from supine to lateral decubitus position. The test is performed by first percussing the midline of the abdomen to elicit a resonant note due to gas in the abdomen.

Mechanical ice auger, showing cutting teeth, helical flights used to transport ice cuttings up away from the cutting region, and a central void for the core itself. Mechanical drilling produces pieces of ice, either as cuttings, or as granular fragments, which must be removed from the bottom of the hole to prevent them from interfering with the cutting or percussing action of the drill. An auger used as the cutting tool will naturally move ice cuttings up its helical flights. If the drill's action leaves the ice chips on top of the drill, they can be removed by simply raising the drill to the surface periodically.

Hutchison was tall, gaunt and appeared rather stooping. His students found his wit to be "caustic" sometimes, reaching "towards sadism in such alliterative condemnations of themselves as a curious collection of crapulous cretins creeping from crib to crib", and making "a newcomer cringe with such reminders as that 'he was percussing a child’s lung not the cellars in the basement'". Yet, his students respected and admired him because, they "sensed that his individual method of teaching was really in part a pose, an assumption of cynicism, that failed to hide a mind that was intellectually gay and a heart that felt deeply for all human suffering, especially the sufferings of children, though seldom for the sufferings of a candidate for the College Membership". Many of Dr Hutchison’s clinical sayings became popular with his contemporaries and future generations.
