| 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 scanning | <investigation, radiology> A nuclear medicine test that involves the inhalation of a radioactive gas and the injection of a radioactive compound into the bloodstream. A special camera measures the radioactive compound and generates a image of the lungs. Comparisons are made between the images generated. Pulmonary embolism can be diagnosed using this procedure. (12 Jan 1998) |
| ventilation-perfusion ratio | The ratio of alveolar ventilation to simultaneous alveolar capillary blood flow in any part of the lung. (12 Dec 1998) |
| ventilation-perfusion scan | A lung function test, especially useful for pulmonary embolism, employing an inhaled radionuclide for ventilation and an intravenous radionuclide for perfusion; their respective distributions in the lung are recorded scintigraphically. (05 Mar 2000) |
| ventilation/perfusion lung imaging | <radiology> See: ventilation agents, perfusion agents, Biello-Siegel criteria (12 Dec 1998) |
| ventilation/perfusion mismatch | An imbalance between alveolar ventilation and pulmonary capillary blood flow. (05 Mar 2000) |
| ventilation/perfusion ratio | The ratio of alveolar ventilation to simultaneous alveolar capillary blood flow in any part of the lung; because both ventilation and perfusion are expressed per unit volume of tissue and per unit time, which cancel, the units become liters of gas per liter of blood. (05 Mar 2000) |
| 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) |
| maximal voluntary ventilation | Measure of the maximum amount of air that can be breathed in and blown out over a sustained interval such as 15 or 20 seconds. Common abbreviations are mvv and mbc. (12 Dec 1998) |
| maximum voluntary ventilation | The volume of air breathed when an individual breathes as deeply and as quickly as possible for a given time (e.g., 15 sec.). Synonym: maximum breathing capacity. (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) |
| middle ear ventilation | Ventilation of the middle ear in the treatment of secretory (serous) otitis media, usually by placement of tubes or grommets which pierce the tympanic membrane. (12 Dec 1998) |
| wasted ventilation | That part of the pulmonary ventilation which is ineffective in exchanging oxygen and carbon dioxide with pulmonary capillary blood; calculated as physiologic dead space multiplied by respiratory frequency. (05 Mar 2000) |
| continuous positive pressure ventilation | Synonym: controlled mechanical ventilation. (05 Mar 2000) |
| 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) |
| controlled ventilation | Intermittent application of mechanically or manually generated positive pressure to gas(es) in or about the airway as a means of forcing gases into the lungs in the absence of spontaneous ventilatory efforts. Synonym: controlled respiration. (05 Mar 2000) |
| high-frequency jet ventilation | Respiratory support system used primarily with rates of about 100 to 200/min with volumes of from about one to three times predicted anatomic dead space. Used to treat respiratory failure and maintain ventilation under severe circumstances. (12 Dec 1998) |

| ventilation |
Ventilation is air circulation of air, typically between a room, a tunnel, etc., and the air outside. When people or animals are present, ventilation is especially necessary to remove the carbon dioxide produced and renew the oxygen used up. It is needed additionally if pollution takes place, e.g. by smoking, painting, etc. ...
