Medical Terminology Simplified

(Grace) #1
Total absence of oxygen (O 2 ) in body tissues
Anoxia is caused by a lack of O 2 in inhaled air or obstruction that prevents O 2
from reaching the lungs.

Collapse of lung tissue, preventing respiratory exchange of oxygen (O 2 ) and carbon
dioxide (CO 2 )
Atelectasis can be caused by obstruction of foreign bodies, excessive secretions, or pressure
on the lung from a tumor. In fetal atelectasis, the lungs fail to expand normally at birth.

Acute inflammation of nasal passages accompanied by profuse nasal discharge; also
called a cold

Acute respiratory syndrome that occurs primarily in children and infants and is
characterized by laryngeal obstruction and spasm, barking cough, and stridor

Genetic disease of exocrine glands characterized by excessive secretions of thick
mucus that do not drain normally, causing obstruction of passageways (including
pancreatic and bile ducts and bronchi)
CF leads to chronic airway obstruction, recurrent respiratory infection, bronchiectasis,
and, eventually, respiratory failure.

Pus in a body cavity, especially in the pleural cavity (pyothorax)
Empyema is usually the result of a primary infection in the lungs.

In the acute form, a severe, life-threatening infection of the epiglottis and surround-
ing area that occurs most commonly in children between ages 2 and 12 with a
sudden onset of fever, dysphagia, inspiratory stridor, and severe respiratory distress
Treatment of epiglottitis involves establishing an open airway for the person to breathe,
including a breathing tube (intubation) and moistened (humidified) oxygen. Also,
intravenous (IV) therapy with antibiotics will be started immediately to help treat
the infection by the bacteria.

Hemorrhage from the nose; also called nosebleed
