人工通气机是借助机械的力量把空气或氧气送入肺内,使之产生或辅助肺间歇性膨胀,以代替、控制或改变自发呼吸,维持或改善肺泡通气和氧合作用,减轻机体缺氧和二氧化碳潴留:减少呼吸肌剧烈活动造成的氧和体力消耗:创造良好条件,使自主呼吸早期恢复正常,以便控制原发疾病,从而达到预防或治疗呼吸衰竭的目的。适应症任何原因引起的自主呼吸消失或异常(如微弱,频率过快等),致缺氧及/或二氧化碳潴留(PaO_2<60mmHg,PaCO_2>60mmHg,慢性呼吸衰竭者PaCO_2>70mmHg)都可使用,具体范围如下。
Artificial ventilator is the use of mechanical force to the air or oxygen into the lungs, so that it produces or assist the lungs intermittent expansion, in lieu of, control or change spontaneous breathing, maintain or improve alveolar ventilation and oxygenation, reduce body hypoxia And carbon dioxide retention: Reduce oxygen and physical exertion caused by violent activities of the respiratory muscles: Create good conditions for the early resumption of spontaneous breathing in order to control the primary disease, so as to achieve the goal of prevention or treatment of respiratory failure. Indications of spontaneous respiration caused by any loss or abnormal spontaneous (such as weakness, too fast, etc.), resulting in hypoxia and / or carbon dioxide retention (PaO_2 <60mmHg, PaCO_2> 60mmHg, chronic respiratory failure PaCO_2> 70mmHg) can be used, The specific scope is as follows.
