Term
Description
a antitrypsin   a serum protein produced by the liver and normally found in the lungs that inhibits proteolytic enzymes of white cells from lysing lung tissue; genetic deficiency of this protein can cause emphysema  
🗑
absorption atelectasis   alveolar collapse that occurs when high concentrations of oxygen are given and oxygen replaces nitrogen in the alveoli; if airway obstruction occurs, the oxygen is obsorbed into the bloodstream and the alveoli collapse  
🗑
asthma   a chronic inflammatory lung disease that results in airflow obstruction  
🗑
centrilobular emphysema   type of emphysema often associated with chronic bronchitis in which respratory bronchioles enlarge, the walls are destroyed, and the bronchioles become confluent  
🗑
centrilobular emphysema   type of emphysema often associated with chronic bronchitis in which respiratory bronchioles enlarge, the walls are destroyed, and the bronchiles become confluent  
🗑
chest percussion   rhythmic percussion of a patient's chest with cupped hands to loosen retained respiratory secretions  
🗑
chest physiotherapy   series of maneuvers including percussion, vibration and posrural drainage designed to promote clearance of excessive respiratory secretions  
🗑
chronic bronchitis   obstructive pulmonary disease characterized by excessive production of mucus and chronic inflammaroty changes in the bronchi  
🗑
chronic obstructive pulmonary disease (copd)   pulmonary disease state characterized by the presence of airflow obstruction caused by chronic bronchitis or emphysema; clinical use of the term indicates the presence of chronic bronchitis and/or emphysema  
🗑
cor pulmonale;   hypertrophy of the right side of the heart, with or without heart failure, resulting from pulmonary hypertension  
🗑
cystic fibrosis   an autosomal recessive, multisystem disease characterized by altered function of the exocrine glands involving primarily the lungs, pancreas, and sweat glands  
🗑
diaphragmatic breathing   breathing with the use of the diaphragm to achieve maximum inhalation and slow respiratory rate  
🗑
dry powder inhaler   dry powdered drug delivered by inhalation  
🗑
emphysema   an abnormal permanent enlargement of the airspaces distal to the terminal bronchioles, accompanied by destruction of their walls and without obvious fibrosis  
🗑
hypercapnia   high arterial CO2 pressure (PaCO2>45mm Hg); also called hypocarbia  
🗑
hyperresponsiveness   excessive or exaggerated response to a stimulus; in asthma, leads to bronchoconstriction in response to physical, chemical, or pharmacologic stimuli  
🗑
hypocapnia   low arterial CO2 pressure (PaCO2 35-45mm Hg)  
🗑
metered-dose inhaler   areosolized drug delivered in a specific amount by activating the inhaler or by inhaling  
🗑
normocapnia   normal arterial CO2 pressure (PaCO2 35-45 mm Hg)  
🗑
O2 toxicity   a condition of onygen overdosage caused by prolonged exposure to high lievels of oxygen; may inactivate pulmonary surfactant and lead to development of acute respiratory distress syndrome  
🗑
