Show Answers:

  1. Adventitious breath sounds
    abnormal breath sounds heard over the lungs
  2. alveoli
    small air sacs at the end of the terminal bronchioles that are the site of gas exchange
  3. atelectasis
    incomplete expansion or collapse of a part of the lungs
  4. bradypnea
    slow rate of breathing
  5. bronchial sounds
    those heard over the trachea; high in pitch and intensity
  6. bronchodilator
    medication that relaxes contractions of smooth muscles of the bronchioles; relating to or causing expansion of the bronchial air passages
  7. bronchovesicular
    normal breath souds heard over the upper anterior chest and intercostal area; medium pitched blowing soun
  8. cilia
    microscopic hairlike projections that propel musus toward the upper airway so that it can be expectorated
  9. crackles
    fine crackling sounds made as air moves thru wet secretions in the lungs; occure due to inflammation or congestion and are associated with pneumonia, CHF, bronchitis, COPD
  10. diffusion
    tendency of solutes to move freely throughout a solvent from an area of higher concentration to an area of lower concentration until equilibrium is established
  11. Dry Powder Inhalers (DPI)
    method of inhaled meds; breath activated. A quick breath by the pt that activates the flow of medication eliminating the need to coordinate activating the inhaler while inhaling the medicin at the same time
  12. dyspnea
    difficult or labored breathing
  13. endotracheal tube
    polyvinyl-chloride airway that is inserted thru the nose or the mouth into the trachea using a laryngoscope as a guide
  14. expiration
    act of breathing out; synonym for exhalation; the passive phase is the movement of air out of the lungs
  15. hyperventilation
    condition in which there is more than the normal amount of air entering and leaving the lungs
  16. hypoventalation
    decreased rate or depth of air movement into the lungs
  17. hypoxia
    inadequate amount of oxygen available to the cells
  18. inspiration
    act of breathing in; active phase involves movement of musclesand the thorax to bring air into the lungs
  19. metered dose inhaler (MDI)
    instrument that delivers a controlled dose of medication to narrowed airways with each compression of the canister
  20. nasal cannula
    disposable plastic device that delivers oxygen via two protruding prongs for insertion into the nostrils
  21. nebulizer
    instrument that disperses fine particles of medication into the deeper passage of the respiratory tract where absorption occurs
  22. perfusion
    process by which oxygenated blood passes thru body tissues
  23. plerual effusion
    fluid in the pleural space
  24. pleural friction rub
    continous dry grating sound caused by infalmmation of plerual surfaces and loss of lubricating pleural fluid
  25. pneumothorax
    aire in the pleural space
  26. pulmonary ventilation
    movement of air into and out of the lungs
  27. pulse oximetery
    oninvasive technique that measures the oxygen saturation of arteril blood
  28. respiration
    gas exchange between the atmospheric air in the alveoli and blood in the capillaries
  29. spirometer
    instrument used to measure lung capacities and volumes; one type is used to encourage deep breathing (incentive spirometry)
  30. sputum
    respiratory secretion expelled by coughing or clearing the throat
  31. surfactant
    detergent-like phospholipid that reduces surface tensionof the fluid lining the alveoli preventing their collapse
  32. tachypnea
    rapid rate of breathing
  33. thoracentesis
    aspiration of fluid or air from the pleural space
  34. tracheostomy
    artificial opening made into the trachea thru wich a tracheostomy tube is inserted
  35. vesicular breath sounds
    normal sound of respirations heard on auscultation over peripheral lung areas
  36. wheeze
    continuous, high pitched squeak or musical sound made as air moves thru narrowed or partially obstructed airway passages
