Detailed explanation-1: -An exacerbation of COPD is described as an acute worsening of respiratory symptoms associated with a variable degree of physiological deterioration.
Detailed explanation-2: -Exacerbation: A worsening. In medicine, exacerbation may refer to an increase in the severity of a disease or its signs and symptoms. For example, an exacerbation of asthma might occur as a serious effect of air pollution, leading to shortness of breath.

These factors increase the inflammatory burden in the lower airways, overwhelming the protective anti-inflammatory defences leading to tissue damage.
