• Erythrocyte


  Red blood cells responsible for transportation of oxygen and carbon dioxide
• Etiology


  Study of a cause or causes of a disease
• Eupnea


  Normal respiration
• Exacerbation


  Increase of symptoms and/or activity of disease
• Excision


  The act of cutting away or taking out
• Expectoration


  The act of coughing up and spitting out materials from the lungs and trachea. The material so ejected is sputum
• Expiration


  The act of exhaling or breathing out
• Expiratory obstructions


  Obstructions in any part of the lung that make exhalation difficult
• Expiratory reserve volume (ERV)


  The amount of air that can be exhaled after a normal resting period, not including residual volume; normally 1200 ml in the adult
• External respiration


  The exchange of gases between the lungs and the atmosphere
• Extracellular


  Outside the cell
• Exudate


  Fluid produced by the lining of a cavity, contains microorganisms and cells
• Febrile


  Pertains to fever or elevation of body temperature
• Fetal


  Pertains to the unborn child after the third month of gestation
• Fetid


  Having a foul odor
• Fibrillation


  Disorganized contraction of cardiac muscle tissue, resulting in loss of cardiac output
• Fibrosis


  Abnormal formation of fibrous or scar tissue
• Fibrothorax


  Fibrous tissue inside the thoracic cavity
• Fibrous


  Containing or composed of fibers
• Fistula


  A deep ulcer formed by incomplete closure of a wound or abscess, or an abnormal, tubelike passage within body tissue (e.g., a tracheoesophageal fistula)
• Flail chest


  A condition in which two or more ribs are broken in the anteroposterior aspect of the thorax
• Flow rate


  The speed at which a substance moves; referred to here as the movement of gases through a registering flowmeter
• Foci


  Center of a morbid process
• Function


  The normal or special action of a part
• Functional residual capacity (FRC)


  The amount of air that can be exhaled by force after a normal resting inspiration plus the residual volume (which cannot be exhaled); normally 2400 ml in the adult
• Glycerol (glycerin)


  A colorless syrupy liquid with a sweet taste that mixes easily with water or alcohol and that is incorporated in some aerosol medications to increase the wetting ability of the medicine and to retard evaporation
• Guillain-Barré syndrome (polyneuritis)


  Diffuse infection or irritation of nerves; may affect the respiratory system by causing paralysis of muscles for breathing
• Hamman-Rich syndrome


  Diffuse interstitial pulmonary fibrosis
• Hemithorax


  Half or one side of the thorax
• Hemoglobin


  The red coloring matter of the blood (when oxygenated) in a normal state. The chemical compound found in the red blood cells that combines with oxygen and whose function it is to carry oxygen.
• Hemoptysis


  Spitting or coughing blood or bloodtinged mucus
• Hemorrhage


  Excessive bleeding
• Hemostasis


  The stopping of bleeding or stagnation of blood flow
• Hemothorax


  Blood in the thorax; specifically in the pleural space
• Hering-Breuer reflex


  Nervous impulses that regulate the rhythm and amplitude of respirations
• Histolytic


  Referring to the degeneration of tissues
• Humidifier


  An instrument for adding water vapor to the air
• Humidifying


  The act of adding water vapor to the air
• Humidity


  Water vapor in the air
• Hydrostatic
