Acute Respiratory Distress Syndrome, or ARDS, is exactly what it sounds like.
‘Acute’ means that it happens rapidly.
‘Respiratory distress’ means that a person becomes unable to breathe and oxygenate their blood, and ‘syndrome’ means that it is a group of symptoms that may be caused by any number of underlying conditions.
Air enters the lungs through a series of airways that branch and narrow until they end in clusters of alveoli, which look kinda like a bunch of grapes.
These cell layers are fused to one another by the basement membrane and surrounding the alveoli and blood vessels is connective tissue made up of mostly proteins and water - in a space called the interstitial space.
The alveolar epithelial cells—called pneumocytes—come in two types.
The vast majority are type I pneumocytes, which are thin and have a large surface area, a shape that allows oxygen and carbon dioxide to pass through them easily.
Acute respiratory distress syndrome (ARDS) is a life-threatening lung condition that results in non-compliant lungs and poor blood oxygenation. It is associated with diffuse alveolar and endothelial injury. ARDS can be caused by a number of things, including pneumonia, sepsis, and trauma. Symptoms include shortness of breath, rapid breathing, and blue lips and fingernails.
