Chronic obstructive pulmonary disease (also known as COPD) is distinguished by a reduction in airflow as a result of airway obstruction. Because of the obstruction of the peripheral airways, a volume of air may become trapped within the lungs (i.e., hyperinflation). It is possible for the respiratory rate to increase as a result of inspiration, which takes place just before the lungs are completely evacuated of air. The adaptation to rapid, shallow breathing may lead to fatigue in the muscles of the respiratory system. The dome of the diaphragm can be reduced by hyperinflation, which also shortens the muscle fibres of the respiratory muscles and inhibits muscle contraction. In addition, there is a possibility that the gas exchange is ineffective. Because of this, people with COPD may feel like they can't get enough air, which is called dyspnea or shortness of breath.
