Collapsed Lung

Collapsed Lung
Today, we delve into the mucus-covered world of lungs. I've searched far and wide, to the furthest reaches of the internet to answer lingering questions surrounding the topic of a COLLAPSED LUNG.
What, pray tell, is a collapsed lung?
In accordance with this site, a collapsed lung is a collection of air in the space around your lungs which prevents the lung from expanding to the size of a normal breath, which, by the way is 500 ml. of air.

You may be wondering how can such a thing occur. Well, should the lung become punctured in some way, air would escape from it into the thoracic cavity, which is bad. Even worse, a spontaneous pneumothorax can occur, which is when lung collapse occurs out of the blue, without any evident cause.
Some people who are more prone to lung collapse are those with asthma, smokers, and very thin people.
Tell-Tale signs of this ailment range from sharp chest pains and shortness of breath to more extreme symptoms as changing of skin colour caused by lack of oxygen and rapid heart rate.
You can, however be tested and treated for these symptoms.
