| AVDO2B | arteriovenous oxygen saturation difference, basal |
| AVF | antiviral factor; arteriovenous fistula |
| AVM | arteriovenous malformation; atrioventricular malformation; aviation medicine |
| AVO2 | arteriovenous oxygen ratio |
| cervical compression syndrome | <syndrome> Pain, paresthesias, and sometimes weakness in the area of the distribution of one or more cervical roots, due to pressure of a protruded cervical intervertebral disc. Synonym: cervical compression syndrome. (05 Mar 2000) |
|---|---|
| compression | Increasing physical pressure on a (vital) structure. (16 Dec 1997) |
| compression anaesthesia | Loss of sensation produced by pressure applied to a nerve. Synonym: compression anaesthesia. (05 Mar 2000) |
| compression fracture | <orthopaedics> A spinal fracture, more specifically, of a vertebral body, that results from the axial compression of the vertebra. Compression fractions result in a loss of height of the vertebral body on X-ray. May occur in any region of the spine. Compression fractures occur commonly in post-menopausal females who subject to osteoporosis. (05 Jan 1998) |
| compression molding | The act of pressing or squeezing together to form a shape in a mold, the adaptation of a plastic material to the negative form of a split mold by pressure. See: injection molding. (05 Mar 2000) |
| compression neuropathy | A focal nerve lesion produced when sustained pressure is applied to a localised portion of the nerve, either from an external or internal source; the main source of injury is the pressure differential that exists between one portion of the nerve and another. (05 Mar 2000) |
| compression of brain | Pressure upon the intracranial tissues by an effusion of blood or cerebrospinal fluid, an abscess, a neoplasm, a depressed fracture of the skull, or an oedema of the brain. Synonym: compression of brain. (05 Mar 2000) |
| compression of tissue | The property of tissue that permits it to be moved from an initial or relaxed position or form. Synonym: compression of tissue. (05 Mar 2000) |
| compression paralysis | Paralysis due to external presure on a nerve. (05 Mar 2000) |
| compression plating | A technique for internal fixation of fractures in which plates and screws are applied so as to produce compression of the line of fracture. (05 Mar 2000) |
| compression retinopathy | See: Berlin's oedema. See: traumatic retinopathy. (05 Mar 2000) |
| compression syndrome | Trauma and ischemia of soft tissues, principally skeletal muscle, due to prolonged severe crushing of the tissues, leading to increased permeability of the cell membrane and to the release of potassium, enzymes, and myoglobin from within cells. Ischemic renal dysfunction secondary to hypotension and diminished renal perfusion results in acute tubular necrosis and uraemia. (12 Dec 1998) |
| compression thrombosis | Thrombosis due to arrest of the circulation in a vessel by compression, as from a tumour. (05 Mar 2000) |
| compression wave | <radiobiology> Waves where the quantity which oscillates is the density of the medium, that is the medium at a given point alternately compresses and expands. Low-amplitude compression waves in air or water are commonly known as sound waves, shock waves are a high-amplitude form. Synonym: density wave. (13 Jan 1998) |
| heat of compression | Heat produced when a gas is compressed. (05 Mar 2000) |
