| controlled thermonuclear fusion | <radiobiology> The process in which light nuclei, heated to a high temperature in a confined region, undergo fusion reactions under controlled conditions, with associated release of energy which may be harnessed for useful purposes. (09 Oct 1997) |
|---|---|
| controlled thermonuclear research | General label for research on controlled thermonuclear fusion reactions. (09 Oct 1997) |
| controlled trial | A clinical study in which one group of participants receives an experimental drug while another group receives either a placebo or an approved standard therapy. When participants do not know which group they are in, the trial is blinded. See: Double-Blind. (09 Oct 1997) |
| pressure-controlled respirator | A respirator that provides a predetermined pressure to gases during inhalation, the volume of gas moved being variable, depending upon resistance. (05 Mar 2000) |
| noncondensing, controlled extraction turbine | A turbine that bleeds part of the main steam flow at one (single extraction) or two (double extraction) points. (05 Dec 1998) |
| environment, controlled | A state in which the environs of hospitals, laboratories, domestic and animal housing, work places, spacecraft, and other surroundings are under technological control with regard to air conditioning, heating, lighting, humidity, ventilation, and other ambient features. The concept includes control of atmospheric composition. (12 Dec 1998) |
| alveolar ventilation | The volume of gas expired from the alveoli to the outside of the body per minute; calculated as the respiratory frequency (f) multiplied by the difference between tidal volume and the dead space (VT -VD); units: ml/min BTPS. (05 Mar 2000) |
| artificial ventilation | Application of mechanically or manually generated pressures, usually positive, to gas(es) in or about the airway as a means of producing gas exchange between the lungs and surrounding atmosphere. Synonym: artificial respiration. (05 Mar 2000) |
| assist-control ventilation | Artificial respiration in which inspiration is produced automatically after a set interval if the person has not already begun to inspire. Compare: assisted ventilation, controlled ventilation. (05 Mar 2000) |
| assisted mechanical ventilation | <anaesthetics> The use of a mechanical device to fill the lungs with oxygenated air then allow time for passive exhalation. (27 Sep 1997) |
| assisted ventilation | Application of mechanically or manually generated positive pressure to gas(es) in or about the airway during inhalation as a means of augmenting movement of gases into the lungs. Synonym: assisted respiration. (05 Mar 2000) |
| manual ventilation | Intermittent manual compression of a gas-filled reservoir bag to force gases into a patient's lungs and thus maintain oxygenation and carbon dioxide elimination during apnea or hypoventilation. (05 Mar 2000) |
| ventilation | 1. In respiratory physiology, the process of exchange of air between the lungs and the ambient air. Pulmonary ventilation (usually measured in litres per minute) refers to the total exchange, whereas alveolar ventilation refers to the effective ventilation of the alveoli, in which gas exchange with the blood takes place. 2. In psychiatry, verbalisation of one's emotional problems. Origin: L. Ventilatio (18 Nov 1997) |
| ventilation meter | A meter used to measure tidal and minute ventilatory volumes. (05 Mar 2000) |
| ventilation/perfusion lung imaging | <radiology> See: ventilation agents, perfusion agents, Biello-Siegel criteria (12 Dec 1998) |
