  23. 23. FORMULA FiO2=20 + 4(02 L/min) Trigger Problem: If A 50 year old patient with DOB is given supplemental oxygen via nasal cannula which delivers at 2L/min. How much percentage of oxygen does the patient receives?
  24. 25. <ul>Nasal cannula </ul><ul><li>1-2L/min (23- 30%)
  25. 26. 3-5L/min (30-40%)
  26. 27. 6L/min (23-42%) </li></ul>
  27. 28. <ul>Facial mask </ul><ul><li>6-8 L/min
  28. 29. 40% to 60 % </li></ul>
  29. 30. <ul>Partial rebreather mask </ul><ul><li>8-11 L/min
  30. 31. 50% to 75 % </li></ul>
  31. 32. <ul>Nonbreathing mask </ul><ul><li>12 L/min
  32. 33. 95% to 100% </li></ul>
  33. 34. <ul>Transtracheal O2 catheter </ul><ul><li>1/4 – 4 L/min

  35. 36. <ul>Venturi mask </ul><ul><li>4-6 L/min (24,26,28%)
  36. 37. 6-8 L/min (30,35,40%) </li></ul>
  37. 38. <ul>The colour of the mask’s aperture reflects the FiO2 achieved </ul><ul>Venturi masks…….. </ul><ul>28% </ul><ul>35% </ul><ul>40% </ul><ul>60% </ul>
  38. 39. <ul>Face Tent </ul><ul><li>4 to 8 L/min

  40. 41. 8-10 L/min
  41. 42. (30-100%) </li></ul>
  42. 43. Oxygen Toxicity 2 proposed theories: <ul><li>formation and release of free oxidant radicals
  43. 44. direct injury to endothelial cells and type I epithelial cells </li></ul>Risk of O2 Therapy
  44. 46. Symptoms: <ul><li>substernal burning,
  45. 47. chest tightness, and
  46. 48. nonproductive cough </li></ul><ul><li>reduction in vital capacity and carbon monoxide diffusing capacity </li></ul>Lung Function:
  47. 49. Sequlae of oxygen toxicity: <ul><li>acute, or exudative, phase </li></ul>-begins within 48 to 72 hours - associated with perivascular, interstitial, and alveolar edema with atelectasis, as well as alveolar hemorrhage -reversible.
  48. 50. <ul>b)subacute proliferative phase; </ul>-begins fourth to seventh day -an irreversible phase Clinically, -hypoxemia and diminished compliance progress -CXR features: alveolar-interstitial pattern in an irregular distribution, with evidence of moderate loss of volume from patchy atelectasis.
