Water on the Lung

I was admitted for low electrolytes, especially low K.
They also found me dehydrated and put me on a saline drip 100 ml per hour and no getting out of
bed or exercising.
This caused me to become over-hydrated or have Pleural Effusion

What is Pleural Effusion?
Pleural effusion, also called “water on the lung,” is an excessive buildup of fluids between your lungs
and chest cavity. There is always a small amount of liquid on the outside of your lungs. This fluid
works to coat the membranes that line the outside of your lungs and lubricates the chest cavity to
facilitate breathing. Certain medical conditions can cause this fluid to build up between the chest cavity
and your lungs; this buildup is called pleural effusion.

According to the Cleveland Clinic, pleural effusion is a common condition, with more than 100,000
cases diagnosed in the United States each year (Cleveland Clinic).

How Does Pleural Effusion Develop?
The membrane that lines the outside of the lungs is called the pleura. This membrane normally contains
a small bit of liquid that acts to lubricate the lungs. When this membrane is irritated or infected it
creates an excess of fluid with accumulates in the chest cavity outside of the lung, causing pleural
effusion. Pleural effusions are often caused by certain types of cancer—such as lung, breast, and
ovarian cancers—as well as lymphoma and mesothelioma. Fluid may also build up as a result of certain
cancer treatments, such as radiation therapy or chemotherapy.

Other causes include:

heart failure
cirrhosis (poor liver function)
pulmonary embolism (blockage in one or more of the arteries in your lungs)
post open-heart surgery
kidney disease
