Acute respiratory distress syndrome Prognosis

The prevention of Acute respiratory distress syndrome: ARDS high-risk patients should be closely observed, intensive care, when found shortness of breath, PaO2 reduce lung injury, should be given early respiratory support and other effective preventive measures to prevent the further development of ARDS.

Prognosis of ARDS is related with rescue measures, primary disease and complications. Serious infections such as sepsis due to lack of control, so is very poor prognosis. The mortality rate is almost 100%, when ARDS are complicated by Bone marrow transplantation. If multiple organ failure are complicated by ARDS, also is very poor prognosis, and interrelated with the number of organs involved. If three organ failure is sustained more than one week, case-fatality rate can be as high as 98%. After aggressive treatment, if pulmonary vascular resistance continued to increase, showing a poor prognosis. Fat embolism caused by ARDS, by active treatment, mechanical ventilation will be 90% survival. Irritant gas gas-induced acute pulmonary edema and ARDS, the general out of the scene and treated promptly, can achieve better results. If the other ARDS patients PEEP0.98 (10cmH2O) after treatment, PaO2 increased significantly, a better prognosis. ARDS can be relieved quickly of patients, most can return to normal. Abnormal pulmonary function in 40% of ARDS to restore those, 20% showed obstructive pulmonary ventilation damage, 30% of reduced diffusing capacity, 25% of decline PaO2 in exercise.
