a

panacinar emphysema even without smoking
characterized by chronic airway inßammation; deÞned by symptoms like wheeze, shortness of breath, chest
tightness, and cough varying over time and in intensity
bronchiectasis
chronic, irreversible dilation of the bronchi and bronchioles that results from the destruction of muscle/
elastic connective tissue; dilated airways become saccular and are a medium for chronic infection
chest percussion
manually cupping hands over the chest wall and using vibration to mobilize secretions mechanically
dislodging secretions in the lungs
therapy used to remove bronchial secretions, improve ventilation, and increase the efÞciency of the
respiratory muscles; types are postural drainage, chest percussion, vibration, and breathing retraining

compact, portable inspiratory inhaler delivering dry-powder medications into the patientÕs lungs
characterized by destruction of the walls of overdistended alveoli
portable handheld mucous clearance device; has a tube with an oscillating steel ball inside; on expiration,
high-frequency oscillations facilitate mucous expectoration
fraction of inspired oxygen (FiO )
concentration of oxygen delivered
hypoxemia
decrease in arterial oxygen tension in the blood
decrease in oxygen supply to the tissues and cells
polycythemia
increase in red blood cell concentration in the blood; in COPD, the body attempts to improve oxygen-
carrying capacity by producing increasing amounts of red blood cells
