Epidemiological data
The annual incidence of ARDS is 13-23 people per 100,000 in the general population and it is higher in the mechanically ventilated population in intensive care units which represents 16.1% percent in ventilated. Pneumonia and sepsis are considered as leading trigger of ARDS as pneumonia represent in up to 60% of patients and may be either causes or complications of ARDS and according to literature approximately 30% of patients with severe sepsis may develop ARDS or ALI. Other triggers include aspiration, circulatory shock, mechanical ventilation, smoke inhalation, trauma especially pulmonary contusion major surgery, massive blood transfusions, drug reaction or overdose, fat emboli and reperfusion pulmonary edema after lung transplantation or pulmonary embolectomy. Alcohol excess appears to increase the risk of ARDS. Until the 1990s, majority of studies reported a 40-70% mortality rate for ARDS. However, 2 reports in the 1990s, one from a large county hospital in Seattle and one from the United Kingdom, suggested much lower mortality rates, in the range of 30-40%. Possible explanations for the improved survival rates may be better understanding and treatment of sepsis, recent changes in the mechanical ventilation, and better overall supportive care of critically ill patients. (Koh et al, 2012)
We noticed that most deaths in ARDS are related to sepsis or multiorgan failure rather than to a primary pulmonary cause, although the recent success of mechanical
