The condition is associated with extensive pulmonary inflammation and small blood vessel injury in all affected organs. It is difficult to estimate the incidence of ARDS because it is often associated with other severe illnesses. But it is a common problem in hospital intensive care units.

The incidence of ARDS has been difficult to determine, due partly to the variety of causes. Various published estimates have ranged from 1. Other figures suggest the occurrence of 13, to 27, cases annually.

Pathophysiology ARDS is the end result of acute alveolar injury caused by a variety of insults and probably initiated by different mechanisms. The initial injury is to either the capillary endothelium or alveolar epithelium. There is increased capillary permeability, Organization and scarring follows.

The capillary defect is produced by an interaction of inflammatory cells and mediators, including leukocytes, cytokines, oxygen radicals, complement and arachidonate metabolites, that damages the endothelium and allows fluid and proteins to leak. Endotoxin, neutrophils and macrophages may also play key roles in the pathogenesis of ARDS.

ARDS results from widespread acute injury to the alveolar capillary membrane.

This produces high permeability edema, visible on the chest x-ray. It also inhibits surfactant function especially fibrin monomers. Epithelial injury also impairs new surfactant synthesis. Inflammation may exacerbate the injury because of release of oxidants and lysosomal enzymes from activated leukocytes.

Causes, incidence, and risk factors: ARDS is a medical emergency. It may be caused by a variety of conditions that directly or indirectly cause the blood vessels to "leak" fluid into the lungs. The ability of the lungs to expand is severely decreased and damage to the air sacs and lining endothelium of the lung is extensive.

Blood concentration of oxygen remains very low in spite of high concentrations of supplemental oxygen given to the patient. Systemic causes of lung injury include trauma, head injury, shock, sepsis, multiple blood transfusions, and medications.

Pulmonary causes include pulmonary embolism, severe pneumonia, smoke inhalation, radiation, high altitude, near drowning, and more.

Symptoms usually develop within 24 to 48 hours of the injury or illness. Cigarette smoking may be a risk factor.

Less common causes include drowning and inhalation of toxic gases.

In half the cases, onset occurs within 24 hours of the original illness or injury ;in nearly all, it occurs within three days. Recent data suggests that on average more than 40 percent die from ARDS.Acute respiratory distress syndrome (ARDS) is a sudden progressive form of acute respiratory failure in which the alveolar capillary membrane becomes damaged and more permeable to intravascular fluid.

Acute respiratory distress syndrome (ARDS) occurs within a critically ill individual who demonstrates failures within breathing due to essential illnesses. Though, acute respiratory distress syndrome is not defined as a precise disease and/or illness, “it is a life-threatening condition that occurs when there is a severe fluid buildup in both.
