  1. Consists of the mouth and nasal cavity and passages, pharynx and trachea, which collectively connect the respiratory zone of the lungs to the atmospheric air surrounding the body.
    Conducting Zone
  2. Consists of the respiratory bronchiles and alveoli ducts and alveoli, which collectively represent the sites of pulmonary gas exchange.
    Respiratory Zone
  3. What are the causes of pulmonary disease?
    Genetic causes, environment, or smoking
  4. Poor gas exchange between ambient air and pulmonary capillary blood.
    Pulmonary disease
  5. COPD causes a ___ in VO2 max.
    reduction
  6. What are the 2 main categories of pulmonary disease?
    COPD and Restrictive lung diseases
  7. COPD causes a?
    reduction in airflow, and SOB in exertion.
  8. What happend during chronic bronchitis?
    persistant sputum production caused by thickened bronchial wall and excess secretions.
  9. What happens during bronchial asthma?
    bronchial smooth muscle contraction and airway restrictions
  10. What is Emphysema?
    • Loss of elastic recoil of alveoli and bronchioles
    • enlargment of alveoli and bronchioles
    • airways can collapse diring exhalation
  11. What happens during asthma attack?
    airway restriction and smooth muscle contraction
  12. Treatment for asthma?
    Bronchodilators
  13. Asthma affects ___ Americans.
    14.6 MILLION
  14. Causes of asthma?
    Allergic reaction to dust, pollen, smoke, pollution, exercise, or viral infections
  15. Exercise induced Asthma causes ___ to restrict.
    bronchioles
  16. what test is used to test for EIA? And what results show positive?
    • FEV1 test
    • if there is a 15% reduction after exercise compared to pretest values
  17. What is Cystic Fibrosis?
    • A type of COPD
    • Recessivley inherited genetic disorder.
    • Affects 1 in 2500 caucasian kids
    • thick mucus blocks air exchange
    • aerobic exercise helps clear lungs
    • percussion of lungs helpful
  18. Restrictive lung disease is caused by?
    • kyphoscoliosis
    • pectus excavatum
    • coal dust
    • asbetosis
    • chemotherapy
    • radiation therapy
    • obesity
    • pregnancy
  19. What is Restricive lung disease?
    air does not get trapped but a reduced amount is taken in. so there is an incresed work in breathing.
  20. Total volume of air in lungs
    total lung capacity
  21. the max volume of air that can be exhaled from lungs in one expiratory volume
    vital capacity
  22. the volume of air remaining in lungs after forced max exhalation
    residual volume
  23. the amount of air remininf in lungs after you conpleted a respiratory cycle
    inspired capacity
  24. volume of air in lungs after normal expiration
    functional residual capacity
  25. volume of air ventilated into and out of lungs with each breath, (aka normal breathing)
    tidal volume
  26. Max volume of air that can be moved in 1 second.
    FEV1 (forced exiratory volume)
  27. the volume of air that can be breathed when going fron mas inhalation to max exhalation
    VC (vital capacity)
  28. What is Obstructive lung disease ?
    • less than 80% capacity of FEV1
    • air is taken in but trapped
    • increased dead space
  29. Exercise for people with COPD has little effect on VO2max, lung function, or mortality rate.
    What are benefits?
    • improve functional capacity
    • better quality of life
    • dyspnea relief
  30. exercise presciption for pulmonary patients
    • rhythmic dynamic exercise
    • 3-5 times a week
    • at leat 30 min a session
    • resistance training recommended
  31. what is hypoxemia?
    decreased arterial oxygen content
  32. When SaO2 values are below 90%?
    O2 supplementation is needed.
  33. Exercise Rx for COPD

    Mode
    Aerobic
  34. Exercise Rx for COPD

    Frequency
    3-5 days/week
  35. Exercise Rx for COPD

    Intensity
    • mild-moderate- @ aerobic threshold on noticable dyspnea
    • severe- symptoms of dyspnea are guiding factor
  36. Exercise Rx for COPD

    Duration
    10-30 min
  37. Supplemental O2 to keep SaO2 level above ___%. is consideration for pulmonary disease.
    90
  38. Pursed lip breathing is considered for patients with___.
    Emphysema
  39. Bronchodilators treat ___.
    asthma and COPD(bronchitis)
  40. what do bronchodialtors do?
    inhibit bronchial smooth muscle constriction
  41. Bronchodilators at rest might?
    • increase Hr
    • Arrhythmias
    • BP
  42. Bronchodilators during exercise might?
    • increase HR. BP Pvc's
    • Arrythmias
    • increase capacity for patients with asthma and COPD
