急性呼吸窘迫综合征患儿肺力学特点

急性呼吸窘迫综合征(acute respiratory distress syndrome,ARDS)的病因不一,发病机制各有所异,病情进展过程中肺力学的改变存在个体差异。顺应性、压力、容量等的变化与病因、病情轻重、年龄等密切相关。正确采用肺保护性通气策略、合理调节呼吸机参数、减少呼吸机相关性肺损伤是提高ARDS救治成功率的关键。因此,在ARDS机械通气治疗中必须高度注意患儿肺力学的特点和变化。

Pulmonary mechanical characteristics of children with acute respiratory distress syndrome

The etiology and pathogenesis of acute respiratory distress syndrome(ARDS)are different.There are individual differences in the changes of pulmonary mechanics during the progress of the disease.The changes of compliance,pressure and volume are closely related to the etiology,severity and age.Correct use of lung protective ventilation strategy,reasonable adjustment of ventilator parameters and reduction of ventilator-associated lung injury are the key to improve the success rate of ARDS treatment.Therefore,we must pay more attention to the characteristics and changes of pulmonary mechanics in ARDS.
