Chronic Obstructive Pulmonary Disease (COPD), also known as chronic obstructive lung disease (COLD), and Chronic Obstructive Airway Disease (COAD), among others, is a type of obstructive lung disease characterized by chronically poor airflow. It typically worsens over time, with the main symptoms including shortness of breath, cough, and sputum production. The technology needed to diagnose and quantitative the individual small airway and emphysema phenotypes present in people with COPD is being developed, and should prove helpful in the assessment of therapeutic interventions designed to modify the progress of either phenotype. COPD remains frequent and costly disease representing one of the principal demands of the public health worldwide. Inhaled tobacco smoke and other noxious particles, such as occupational exposures and smoke from biomass fuels, are the most important exogenous factors that influence disease development and progression. The most important bacterial causes of exacerbations of COPD are nontypeable Haemophilus influenzae, Moraxella catarrhalis, Streptococcus pneumoniae and Chlamydia pneumonia. Despite being a treatable and preventable disease, the prevalence continues to rise because of the worldwide epidemic of smoking. It has systemic effects, and common co-morbid conditions such as cardiovascular disease, muscle wasting and osteoporosis may all be linked through a common systemic inflammatory cascade. Spirometry is essential for the diagnosis of COPD, but the criteria defining airflow limitation are not clear cut for elderly patients and could result in over-diagnosis.
