antihistamines common term for drugs that block the H1 receptors
antitussives drugs that block or suppress the act of coughing
aspiration inhalation of fluids from the mouth and throat
asthma a reversible lung disease with intermittent attacks in which inspiration is obstructed; provoked by airborne allergens
bronchitis a condition in which the inner lining of the bronchial airways becomes inflamed, causing the expiration of air from the lungs to be obstructed
bronchodilator an agent that relaxes smooth-muscle cells of the bronchioles, thereby increasing airway diameter and improving the movement of gases into and out of the lungs
bronchospasm spasmodic contraction of the smooth muscles of the bronchiole
corticosteroid a drug that chemically resembles substances produced by the adrenal gland and acts as an anti-inflammatory agent to suppress the immune response by stimulating adenylate cyclase
cotinine a major metabolite of nicotine
cough reflex a coordinated series of events, initiated by stimulation of receptors in the lungs and airways, that results in a cough
cystic fibrosis (CF) a hereditary disorder of infants, children, and young adults that involves widespread dysfunction of the gastrointestinal and pulmonary systems
decongestant an agent that causes the mucous membranes to shrink, thereby allowing the sinus cavities to drain
emphysema an irreversible lung disease characterized by destruction of the alveoli in the lungs, which allows air to accumulate in tissues and organs
expectorant an agent that decreases the thickness and stickiness of mucus, enabling the patient to rid the lungs and airway of mucus when coughing
histoplasmosis a respiratory tract infection caused by a fungus, most often found in accumulated droppings from birds and bats; often called the summer flu
irritant receptor a nerve cell in the lungs and airways that responds to coarse particles and chemicals to trigger a cough
leukotriene inhibitor an agent that blocks the body's inflammatory responses to the leukotrienes or blocks their synthesis
mast cell stabilizer an agent that stabilizes mast cell membranes against rupture caused by antigenic substances and thereby reduces the amount of histamine and other inflammatory substances released in airway tissues
metered dose inhaler (MDI) a device that delivers a specific amount of medication (as for asthma) in a fine enough spray to reach the innermost parts of the lungs using a puff of compressed gas
monoclonal antibody an antibody produced in a laboratory from an isolated specific lymphocyte that produces a pure antibody against a known, specific antigen
mucolytic an agent that destroys or dissolves mucus
nebulizer a device used in the administration of inhaled medications, using air flowing past a liquid to create a mist
nicotine the addictive component of tobacco
peak expiratory flow rate (PEFR) the maximum flow rate generated during a forced expiration, measured in liters per minute
peak flow meter a device used to measure the PEFR as an indication of respiratory status; usually used twice a day by asthma patients
percussion a therapy used for cystic fibrosis (CF) patients involving a tapping movement to induce cough and expectoration of sputum from the lungs; usually preceded by nebulizer therapy during which nebulized sterile water or normal saline is breathed to liquefy pu
pneumonia a common lung infection, caused by microorganisms that gain access to the lower respiratory tract
respiratory distress syndrome (RDS) a syndrome occurring in newborns that is characterized by acute asphyxia with hypoxia and acidosis
rhinitis medicamentosa a condition of decreased response that results when nasal decongestants are used over prolonged periods
spacer a device used with a metered dose inhaler (MDI) to decrease the amount of spray deposited on the back of the throat and swallowed
status asthmaticus a medical emergency that begins as an asthma attack but does not respond to normal management; can result in loss of consciousness and death
stretch receptor a nerve cell in the lungs and airways that responds to elongation of muscle to trigger a cough
surfactant a fluid that reduces surface tension between the air in the alveoli and the inner surfaces of the alveoli, allowing gas to be exchanged between the lung and the air
tachypnea very rapid respiration causing a flushed appearance; a characteristic ofemphysema
tuberculosis (TB) a disease of the lungs and other body tissues and organs caused by Mycobacterium tuberculosis
xanthine derivative a drug that causes relaxation of airway smooth muscle, thus causing airway dilation and better air movement
