Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. [1] Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). [ 1 ]
The pathophysiology of acute respiratory distress syndrome involves fluid accumulation in the lungs not explained by heart failure (noncardiogenic pulmonary edema). It is typically provoked by an acute injury to the lungs that results in flooding of the lungs' microscopic air sacs responsible for the exchange of gases such as oxygen and carbon dioxide with capillaries in the lungs.

Acute respiratory distress syndrome (ARDS), a severe lung condition occurring in response to a critical illness or injury. Infant respiratory distress syndrome due to a deficiency of surfactant in the lungs of a baby born prematurely. Tuberculosis [4] Many cases of restrictive lung disease are idiopathic (have no known cause).
The respiratory disturbance index (RDI)—or respiratory distress Index—is a formula used in reporting polysomnography (sleep study) findings. Like the apnea-hypopnea index (AHI), it reports on respiratory distress events during sleep, but unlike the AHI, it also includes respiratory-effort related arousals (RERAs). [ 1 ]
There are two forms of respiratory distress syndrome: ARDS , which is acute (or adult ) respiratory distress syndrome Infant respiratory distress syndrome (IRDS), which is a complication of premature birth, also known as hyaline membrane disease (HMD)
As expected, the mortality rates increase as the severity of the ARDS increases with mortality rates at approximately 35%, 40%, and 46% for mild, moderate, and severe, respectively. [11] It has been revealed that patients with ARDS that show DAD on histology are at a high mortality rate of 71.9% compared to 45.5% in patients with ARDS but ...
