Exam 3 Part 5
Show Answers:

    the second heart sound(S2)

  11. Changes in closing volume and closing capacity affect?
    gas exchange.
  12. is the volume of gas in the lungs in excess of RV at end exhalation

    monitor ventilatory parameters
  18. The ventilatory measurements that can be monitored at the bedside in the ICU include:
    Lung volumes/flows, airway pressures, fractional gas concentrations

  20. critical value for VT
    <4-5ml/kg or <300 ml

  22. crtical frequency of breath
  23. Rapid shollow breathing index
    >105 w/o PS or CPAP
  24. dead space/VT ratio normal value
  25. crtical value of deapspace/Vt ratio
  26. Minute Vol. norm.
  27. crtical value for VE
  28. Norm VC
  29. Crtical value of VC
  30. Max. Inspiratory Pressure norm (Pimax)
    -80--100 cm H2O
  31. Critical value of Max Inspir. press. (Pimax)
    0-20 cm H2O
  32. is the p[rocess of moving gases between the atmosphere and the lung
  33. The four reasons why lung volumes are improtant to the clinician are:
    affect of gas exchange, rflect clinical status, indicate responce to therapy, and signal problem between patient and vent. interface.
  34. Intubated patients, patients being considered for or being weaned from mechanical vents, and patients with an abnormal breathing patter, and intubated patients should be monitored for what?
    Lung volumes
  35. Nonintubated patients: preoperative eval., adults w/ RR > 30bpm, w/ neuromuscular diseases, CNS depression, deteriorating blood gases, and patients recieveing noninvasive positive pressure vent. should be monitored for?
    lung volumes
  36. is defined as the volume of air inspired or passively exhaled in a normal respiratory cycle.
    Tidal Volume
  37. VT has two components:
    Alveolar volume VA and dead space volume VD
  38. portion of VT that effectively exchanges with alveolar-capillary blood
  39. the portion of VT that does not exchange with capillary blood
  40. VD is normal what percentage of VT
  41. The conductive airways and alveolar units that are ventilated but not perfused create the true or?
    physiological dead space.
  42. If VD increases to 60% the patient may need?

  43. how many sighs in an hour?
  44. a VT less than 5ml/kg is?
    indication of resp. prob.
  45. Rapid and shollow breathing in a critically ill patient at rest may indicate?
    impending respiratory failure
