Show Answers:

  1. What is ERV, expiratory reserve volume
    volume of gas that can be exhaled beyond a normal tidal exhalation
  2. What is IRV, inspiratory reserve volume
    volume of gas that can be inhaled beyond a normal tidal inhalation
  3. What is RV, residual volume
    volume of gas remaining in lungs after ERV has been exhaled
  4. Define hyper/hypoxemia and what is normal range
    • high or low oxygen level in blood
    • WNL adults:80-100mm Hg
    • WNL child: 75-80mm Hg
  5. Define hyper/hypocapnemia and what is WNL
    • high or low CO2 in blood
    • WNL adult: 35-45mm HG
    • WNL child: 34-54mm HG
  6. With respiratory acidosis/alkalosis what is high or low in the blood? Whats normal PH level?
    • acidosis=too much co2
    • alkalosis= too much O2
    • 7.3-7.45 normal PH level
  7. what is tidal volume and what is normal for adults and children
    • the amount of gas inhaled and exhaled during a normal breath
    • WNL adults: 500ml
    • WNL children: 20ml
  8. What is functional residual capacity.
    The amount of air that resides in lungs after a normal resting tidal exhalation
  9. What is VC, vital capacity
    amount of air that is under volitional control, measured as a FVC, forced vital capacity
  10. What is FEV (forced expiratory volume)1? What is healthy?
    Healthy is FEV 70% of total FVC (forced vital capacity) in one second.
  11. With COPD which is increased? IRV (inspiratory reserve volume) or RV (reserve volume), why and what problem does this cause?
    • RV
    • This means after a normal exhale there is still a large volume of air in lungs. Air is "trapped". Does not leave much room for inhalation.
  12. Asthma and CF results in hyperinflation or hypoinflation?
    hyperinflation, air is trapped and FEV1 is decreased
  13. What occurs with restrictive lung disease?
    • Lungs have difficulty expanding
    • IRV is increased (inspiratory reserve volume)
  14. differences between COPD and restrictive lung disease?
    restrictive has non-productive cough, expiratory flow rates are near WNL with restrictive, and decreased chest expansion with restrictive
  15. What is clubbing and is it a sign of hypo or hyper oxia
    • hypo
    • tips of fingers become bulbous and bluish
  16. Norms for HR, BP, RR for adults
    • HR: 60-100bpm
    • BP: <120/80mm HG
    • RR: 12-20 br/min
  17. Norms for HR, BP, RR for infants
    • HR: 120 bpm
    • BP: 75/50mm HG
    • RR: 40 br/min
  18. what type of breath sound is vesicular?
    • normal
    • soft rustling sound heard throughout all of inspiration and beginning of expiration
  19. what breath sound is bronchial
    • more hollow, echoing sound
    • normal, heard at right superior anterior thorax
  20. what is crackles (rales or crepitations) and what is it associated with
    • crackling sound usually with inspiration
    • that indicated atelectasis, fibrosis, pulmonary edema
  21. what is Atelectasis
    part(s) of a lung collapse or fail to inflate normally
  22. what is wheezes and what is it associated with?
    • "musical" pitched sound normally heard with expiration caused by airway obstruction
    • asthma, COPD, aspiration
