Table 1. In this phase, the injury of alveolar capillary endothelial cells and type I pneumocytes lead interstitial alveolar edema non cardiogenic pulmonary edema and atelectasis. Once in the lungs, oxygen is moved into the bloodstream and carried throughout the human body. Many people who survive ARDS have memory loss or other quality-of-life problems after they recover.

Sometimes, a treatment called extracorporeal membrane oxygenation ECMO is done. Endotheial fibroproliferation in the pulmonary vasculature leads to progressive vascular occlusion and pulmonary hypertension. Last, the use of pulmonary artery catheters has been decreasing over the last few years, precluding measurements of pulmonary artery occlusion pressures.

The three phases are Exudative, Proliferative, and Fibrotic. In some cases, a healthy person has severe pneumonia that gets worse and becomes ARDS.

Extracorporeal membrane oxygenation ECMO may be used to increase oxygen levels. This term was later modified to acute respiratory distress syndrome ARDSwhen similar cases were reported across all age groups. Patients with a higher body-mass index have an increased incidence of ARDS, but its association with mortality is not clearly defined 26 — Since these entities were originally described, multiple definitions or diagnostic criteria have been proposed.
