|---|---|---|---|
| 설명 | 인간이나 동식물의 건강-생활에 피해를 주는 인위적 발생원으로 인해 대기가 오염된 상태. 인간사회의 생산-유통-소비의 각 과정에서 배출되는 대기오염물질에 의해 사람의 건강은 물론 동식물-토양-지형-기후-수리 등으로 얽힌 생태계의 안정성이 방해될 때를 대기가 오염되었다고 한다. 여기에서 대기오염물질이란 대기의 조성을 변화시켜 인간사회나 생태계에 영향을 미칠 정도로 존재하는 천연 또는 인공물질을 말하며, 고체-액체-기체 또는 이들의 혼합물이 포함된다. 단일한 물질만으로 된 대기 오염물질은 드물며, 일반적으로는 많은 종류와 크기로 된 복합물질이다. 크게 나누면, 특정한 발생원에서 직접 방출되는 일차 오염물질과, 두 종류 이상의 일차 오염물질에 의한 상호작용이나 광화학반응 등에 의해 생긴 이차 오염물질이다. 매연, 먼지, 일산화탄소 따위와 같은 물질이 공기와 섞이는 일이 대기오염의 예이며, 그뿐 아니라 이산화탄소의 증가로 인하여 지구의 온난화, 그리고 프레온 가스로 인한 오존층의 파괴 따위가 문제시되고 있다. |

| mixed expired gas | <physiology> One or more complete breaths of expired gas coming thoroughly mixed from the dead space and the alveoli. (05 Mar 2000) |
|---|---|
| expired gas | Any gas that has been expired from the lungs; often used synonymously with mixed expired gas. (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) |
| 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) |
| 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. (12 Dec 1998) |
| 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) |
| 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) |
