Healthy air sacs are elastic and very stretchy. COPD has a range of effects on the lungs that reduce their ability to take in oxygen and distribute it to organs in the bloodstream. In many cases an exacerbation is caused by an infection in the lungs, but in some cases, the cause is never known.

Acute exacerbation of COPD is a flare-up or episode in which a person’s breathing becomes worse than usual, and they struggle to maintain their oxygen levels. When a person with healthy lungs inhales air, it travels down their windpipe and into the airways of the lungs, known as bronchial tubes. endobj Pathophysiology describes the changes a disease or condition causes in a person’s physical function as it develops. This can lead to problems with thought processes, confusion, and high blood pressure in the blood vessels around the lungs. This leads to the presence of more air than usual. ͐,.�.
