Lower respiratory disorders are conditions that obstruct or restrict tracheobronchial tubes and prevent the exchange of gas within the lungs. These conditions are referred to as chronic obstructive pulmonary disease (COPD) and include chronic bronchitis, bronchiectasis, emphysema, and asthma.

COPD obstructs the patient's airway by increasing resistance of the airflow during inspiration and expiration. The result is an impairment of oxygen reaching lung tissues that can in some cases irreversibly damage lung tissues.

The airway obstruction occurs when the bronchioles constrict (bronchospasm) and mucous secretions increase causing the patient to experience difficulty breathing (dyspnea).
