Abstract:
Acute respiratory distress syndrome(ARDS) can be divided into pulmonary ARDS and extrapulmonary ARDS according to its origin.The prevalent damage in early stages of pulmonary ARDS is intra-alveolar,whereas in extra-pulmonary ARDS it is the interstitial edema.In pulmonary ARDS,lung compliance is worse than in extrapulmonary ARDS,whereas the main abnormality is the decrease in chest Wall compliance.due to abnormally high intra-abdominal pressure.Positive end expiratory pressure,recruitment maneuver and prone position ventilation are more effective in extrapulmonary ARDS,whereas low tidal volume ventilation play equal role in rescuing the two types of ARDS.
