    collapsed alveoli
  4. Biot's (cluster) respiration
    shallow breaths interrupted by apnea
  5. Cheyne-Stokes respirations
    marked rhthmic waxing and waning of respirations, from very shallow to very deep, with short periods of apnea
  6. Bradyapnea
    abnormally slow breathing

    bluish discoloration of the skin, nailbeds, and mucous membranes
  8. Diffusion
    movement of gases from an area of greater pressure to an area of lower pressure
  9. Emphysema
    lung disorder cahracterized by elevated carbon dioxide levels, barrel chested appearance, and a hypoxic drive as main stimuli for respiration
  10. Erythrocytes
    red blood cells
  11. Eupnea
    normal respirations
  12. expectorate
    spit out
  13. hematocrit
    the percentage of blood that is erythrocytes
  14. hemoglobin
    oxygen carrying red pigment
  15. hemothorax
    accumulation of blood in the pleural space
  16. Humidifiers
    devices that add water vapor to inspired air
  17. Hypercapnia
    increased levels of CO2
  18. Hypercarbia
  19. Hyperinflation
    involves giving patient breaths of greater volume than set on ventilator or via manual resuscitation bag
  20. Hyperoxygenation
    performed by increasing oxygen flow before and after suctioning attempts
  21. Hyperventilate
    increasing the number of breaths the patient is receiving
  22. Hypoxemia
    low levels of oxygen in the blood
  23. Incentive spirometers
    measure flow of air inhaled through mouthpiece; used to improve pulmonary ventilation
  24. Intrapleural pressure
    pressure in the pleural cavity surrounding the lungs
  25. Intrapulmonary pressure
    pressure within the lungs

    form of hyperventilation that accompanies metabolic acidosis
  27. lung compliance
    stretchability of lung tissue
  28. lung recoil
    continual tendency of the lungs to collapse away from the chest wall
  29. Mucous clearance device (MCD)
    used for patients with excessive secretions; assists in loosening mucus
  30. Noninvasive ventilation
    use of a mask that delivers pressurized oxygen without need for invasive tube

    inability to breathe easily unless sitting upright
  32. oxyhemoglobin
    compound of oxygen and hemoglobin carried to tissues

  35. Pneumothorax
    air collected in the pleural space
  36. Postural drainage
    drainage by gravity of secretions from various lung segments
  37. Respiratory membrane
    where gas exchange occurs between air on alveolar side and blood on the capillary side

    harsh, high-pitched sound during inspriations
  40. Suctioning
    aspirating secretions through a catheter connected to a suction machine or wall suction outlet

    the amount of air inspired and expired with each breath
  44. Torr
    millimeters of mercury
  45. Vibration
    series of vigorous quiverings produced by hands that are placed flat against the patient's chest wall
  46. Dyspnea
    difficult or labored breathing
  47. Hypoxia
    insufficient oxygen anywhere in the body
