| mechanical heart | Term loosely applied to any mechanical circulatory assist device. (05 Mar 2000) |
|---|---|
| mechanical ileus | Obstruction of the bowel due to some mechanical cause, e.g., volvulus, gallstone, adhesions. (05 Mar 2000) |
| mechanical intelligence | The capacity to understand and manage technical mechanisms. (05 Mar 2000) |
| mechanical jaundice | Jaundice resulting from obstruction to the flow of bile into the duodenum, whether intra-or extrahepatic. Synonym: mechanical jaundice. (05 Mar 2000) |
| mechanical stage | <microscopy> A device provided for adjusting the position of a specimen, usually by translation in two directions at right angles to each other. (05 Aug 1998) |
| mechanical strabismus | Strabismus due to restriction of action of the ocular muscle within the orbit. (05 Mar 2000) |
| mechanical tubelength | <microscopy> Measurement from the shoulder of the objective to the upper end of the drawtube. The generally accepted length for most microscopes is now 160 mm. Metallographic objectives and some others are corrected for use with longer tube lengths - 190 to 215 mm or more. See: optical tubelength. (05 Aug 1998) |
| mechanical vector | A vector that conveys pathogens to a susceptible individual without essential biological development of the pathogens in the vector, as in the transfer of septic organisms on the feet or mouth parts of the housefly. (05 Mar 2000) |
| mechanical ventilation | <anaesthetics> Mechanically assisted breathing using a electrically powered device that forces oxygenated air into the lungs and then allow time for passive exhalation of air. (27 Sep 1997) |
| mechanical ventilator | <apparatus> Mechanically assisted breathing using a electrically powered device that forces oxygenated air into the lungs and then allow time for passive exhalation of air. (27 Sep 1997) |
| mechanical vertigo | Vertigo caused by continued rotation or vibration of the body. (05 Mar 2000) |
| viscous mechanical coupling | <cell biology> Method by which adjacent cilia are synchronised in a field. Coupling is through the transmission of mechanical forces, rather than of a synchronising signal. (18 Nov 1997) |
| controlled mechanical ventilation | Artificial ventilation in which all inspirations are provided by positive pressure applied to the airway. Synonym: continuous positive pressure breathing, continuous positive pressure ventilation, intermittent positive pressure breathing, intermittent positive pressure ventilation. (05 Mar 2000) |
| stage mechanical | <microscopy> A small fixture, either built into the light microscope stage or attached separately, it holds the specimen slide and has two horizontal screw adjustments at right angles to each other. The screw motions permit the specimen to be moved as desired. The quantitative type has vermer scales for reading the amount of displacement to 0.1 mm. This stage is sometimes called the traversing stage. (05 Aug 1998) |
| stress, mechanical | A purely physical condition which exists within any material because of strain or deformation by external forces or by non-uniform thermal expansion; expressed quantitatively in units of force per unit area. (12 Dec 1998) |
