ARDS一般指由多种疾病过程或直接肺损伤所致的弥散性肺损伤过程。都各有其始因,但有相同的肺反应。 ARDS的现代概念与五六十年代时描述的出血性休克后的“充血性肺水肿”和“休克肺”已有所不同。当前快速有效的复苏技术和机械通气支持,单纯出血性休克已不再是ARDS的常见原因,而创伤的组织炎性病变即使不伴有休克也直接与ARDS相关,除少数例外(神经源性肺水肿),ARDS可能是由炎性介质始动和维持的。此外由于生命支持措施的进展,ARDS的病程已延长到数周
ARDS generally refers to a variety of disease processes or direct lung injury caused by diffuse lung injury process. Have their own reasons, but have the same lung response. The modern concept of ARDS is different from the “congestive pulmonary edema” and “shock lung” after hemorrhagic shock described in the 1950s and 1960s. With the current rapid and effective resuscitation techniques and mechanical ventilation support, hemorrhagic shock alone is no longer a common cause of ARDS, and tissue inflammatory lesions of the wound are directly associated with ARDS even without shock, with a few exceptions (neurogenic lungs Edema), ARDS may be initiated and maintained by inflammatory mediators. In addition, due to the progress of life support measures, the course of ARDS has been extended to several weeks
