A clinical analysis of acute respiratory distress syndrome in mechanical ventilation based on 20 cases

Objectives To probe into the etiology of acute respiratory distress syndrome(ARDS),the causes of death and the clinical significance of life symptom monitor during mechanical ventilation.Methods A retrospective analysis of 20 patients with ARDS in RICU was carried out.The patients were divided into survivor group and death group,and the data collected were the variables of age,sex,biochemical indicator,blood gas analysis,ICU length of stay,presence or absence of tracteostomy,length of ventilation,ventilation and so on.Results Between the survivor group and the death group there was a significant difference in the time length of ventilation(P=0.015).In the survivor group,there was a significant difference in the level of FiO2,SaO2,resperation rate(RR)and heart rate(HR)before and after the using of mechanical ventilation(P0.05).In the death group,there was an obvious increase in FiO2(P0.01)in the patients before they died,compared with the patients′state without the mechanical ventilation.Conclusion The treatment with mechanical ventilation is the crucial method in sustaining life symptom.FiO2,SaO2,RR and HR are the effective and handy as clinical signs to the patients with mechanical ventilation under the state of maintaining BP and PaO2.
