1. What is the definition of ARDS? Acute respiratory distress syndrome (ARDS) occurs when fluid builds up in the tiny, elastic air sacs (alveoli) in your lungs. More fluid in your lungs means less oxygen can reach your bloodstream. This deprives your organs of the oxygen they need to function.
Acute Respiratory Distress Syndrome (ARDS) is also known as shock lung, wet lung, post perfusion lung and a variety of other names related to specific causes.

What are the associated clinical indicators?

The first signs and symptoms of ARDS are feeling like you can't get enough air into your lungs, rapid breathing, and a low blood oxygen level. Other signs and symptoms depend on the cause of the ARDS. They may occur

Static compliance describes lung compliance when no air is coming in. Static compliance can be decreased by certain medical conditions, including fibrosis and pulmonary hypertension or congestion. Alveolar atelectasis is another factor that can decrease static lung compliance. Static compliance can be increased both by asthma and by the normal effects of growing older. Pulmonary emphysema has the effect of increasing static compliance while simultaneously decreasing dynamic compliance. When calculating whether a patient's static compliance is within normal ranges, doctors must consider whether any of these conditions may be present. Static compliance is always a higher value than dynamic.
How is decreased static compliance demonstrated in the patient’s case?
Dynamic compliance is the measurement of the lungs when in motion, at the end of inspiration and expiration. Dynamic compliance is measured by dividing the tidal volume, the average volume of air in one breath cycle, by the difference between the pressure of the lungs at full inspiration and full expiration. Lung compliance can indicate when there are issues with the lungs. A decreased compliance might show a condition such as fibrosis, which is a formation of excess tissue that inhibits movement. Increased compliance can indicate a state of disease where there is degeneration of tissue that causes the lungs to have to work harder to expand, such as emphysema. With
