Both asthma and COPD are treated with medications such as corticosteroid inhalers and bronchodilators. Supplemental oxygen might be necessary for advanced disease. Pulmonary edema is treated with diuretics and possibly antibiotics, as well as supplemental oxygen.
In severe cases, a procedure may be needed to remove excess fluid from the lungs. Heart disease, pulmonary hypertension, liver disease, and sleep apnea all are treated with a combination of medications and, in some cases, other treatments tailored to the condition. Typically, your symptoms and the results of complementary tests should improve with treatment as well.

The movement of air into the lungs is responsible for bringing with it a fresh supply of oxygen, while the movement of air out of the lungs is responsible for removing carbon dioxide from within the body.
HOT TIP: If you would like to learn more about the differences between gas exchange and ventilation and how this relates to type 1 and type 2 respiratory failure, check out this post! To answer your own question, you should be thinking if there is any pathophysiology affecting the ability for oxygen to get into or across the alveoli. Therefore, think about any condition that will reduce the amount of air coming into the alveoli or any condition that clogs up the alveoli to prevent the movement of oxygen into the bloodstream.
If you remember that these are all forms of a shunt, it makes it easier to remember that shunt is related to issues with air entering the alveoli. HOT TIP : If you would like to learn how to differentiate some of the lung condition s described above on a chest x-ray, check out this post! To answer your own question, you should be thinking if there is any pathophysiology affecting the ability for blood to flow past the alveoli.
Therefore, think about any condition that will reduce blood flow through the pulmonary vasculature. Physiological dead space refers to a condition that results in reduced perfusion to well-ventilated alveoli.
This is something that should not occur in healthy people, like in the conditions described above. This is the million-dollar question, and the answer lies in what pathophysiology caused the hypoxemia in the first place. Does that mean that oxygen therapy should never be applied to patients with absolute shunts?
Not exactly! The bronchial tubes carry air to and from your lungs. Unlike acute bronchitis that comes on suddenly, chronic bronchitis develops over time and causes recurrent episodes that can last months or even years.
The chronic inflammation results in excessive mucus buildup in your airways, which resists airflow in and out of your lungs and continues to worsen. Many people with chronic bronchitis eventually develop emphysema and COPD. Pulmonary edema , also known as pulmonary congestion or lung congestion, is a condition caused by excess fluid in the lungs.
Airway obstruction is a blockage of any part of your airway. It can be caused by swallowing or inhaling a foreign object, or by:. An airway blockage can be mild, blocking only some airflow, to severe enough to cause a complete blockage, which is a medical emergency. A pulmonary embolism is a blood clot in the lungs. A blood clot restricts blood flow, which can damage the lung and other organs.
They are most often caused by deep vein thrombosis , which are blood clots that begin in veins in other parts of the body, often the legs. Blood clots can be caused by injuries or damage to blood vessels, medical conditions, and being inactive for long periods. It involves a series of two scans: one to measure how well air flows through your lungs and the other to show where blood is flowing in your lungs.
The test involves an injection of a radioactive substance that gathers in areas of abnormal airflow or blood flow. This will then show in the images produced by a special type of scanner. You need the right amount of oxygen and blood flow to breathe. Shortness of breath, even if mild, should be evaluated by a doctor. If you or someone else experiences sudden or severe shortness of breath or chest pain, get emergency medical care right away.
A pulmonary embolism is a blood clot that occurs in the lungs. It can damage part of the lung and other organs and decrease oxygen levels in the blood.
