    1. Administration of Oxygen Need for Oxygen Hazards Delivery Devices Hyperbaric Oxygen Other Medical Gases

    2. RsCr 220 2 5 Indications for Oxygen Therapy Suspected or Documented hypoxia Severe trauma MI Post op

    3. RsCr 220 3 Hazards of Oxygen Therapy Ventilatory depression Absorption atelectasis ROP Oxygen toxicity Fire hazard Contamination

    4. Delivery Devices Low and High Flow Getting the gas to the patient

    5. RsCr 220 5 Low Flow Device Definition FiO2 can vary with: Patient’s respiratory rate and pattern Flow of gas from the equipment Equipment reservoir Does NOT fully meet patient’s inspiratory demand Needs additional mixing with room air

    6. RsCr 220 6 Low Flow Oxygen Low Flow Nasal cannula Simple oxygen mask Non-rebreathe mask Face tent

    7. RsCr 220 7 Nasal Cannula

    8. RsCr 220 8 Nasal Cannula Delivers about 24 to 44% FiO2 Flow is set at 1 to 6 liters for adults 0.1 to 0.9 with newborns (special flowmeter) FiO2 varies with patient respiratory rate and volumes Add moisture over 4 L/min or with pt comfort

    9. RsCr 220 9 Simple Mask

    10. RsCr 220 10 Simple Mask Delivers 40 to 50% oxygen Need at least 5 L/min to flush out CO2

    11. RsCr 220 11 Non – Rebreathe Mask

    12. RsCr 220 12 A reservoir system Delivers better oxygenation then simple mask. The most oxygen without intubation 50 to 70% oxygen (some say 80-90-100%)

    13. RsCr 220 13 Something New (VIASYS)

    14. RsCr 220 14 The Hi-Ox 80

    15. RsCr 220 15 Helps patients more ways than one Provides an FiO2 of >80% at a flow of 8 L/min Studies show that high FiO2 Reduces nausea post operatively Reduces s/p infections by 50%

    16. RsCr 220 16 Trach Mask

    17. RsCr 220 17 Trached? Usually blue tubing connected to heated aerosol. Can use transport tee

    18. RsCr 220 18 T-piece

    19. RsCr 220 19 Tee Piece Must be intubated With aerosol mist setup or transport tee

    20. RsCr 220 20 Face Tent

    21. RsCr 220 21 Face Tent Ideal for post anesthesia Not enclosed and claustrophobic Only for low oxygen concentrations

    22. Delivery Devices High Flow Venturi (Entrainment) Mask Aerosol mist setup

    23. RsCr 220 23 Definition of High Flow Meets or exceeds patient inspiratory demand (usually textbook of 30 LPM) Provides precise concentrations despite patients breathing pattern

    24. RsCr 220 24 Why 30 Liters per minute? Based on minute volume Respiratory rate times tidal volume The number of breaths multiplied by the size of the breaths People inspire one-third of the time.

    25. RsCr 220 25 Air Entrainment Mask

    26. RsCr 220 26 Venturi Masks

    27. RsCr 220 27 Entrainment Ratios

    28. RsCr 220 28 Venturi – High flow device Ideal for use with CO2 retainers Matches patient demand Usually 24 to 50% (some have up to 100% running at flush)

    29. RsCr 220 29 Aerosols and Nebulizers Jet nebulizers Small volume nebs Aerosol setups Aerosol output calculations Aerosol density calculations

    30. RsCr 220 30 Keep the flow up!

    31. RsCr 220 31 Monitoring Oxygen Therapy Pulse Oximetry Arterial Blood gases Work of Breathing Tidal Volume and Respiratory Rate Pulse and Blood Pressure

    32. RsCr 220 32 Less common used O2 delivery Head hoods Pendant or reservoir nasal cannula Bi-flow Tracheal catheters Croup tents Incubators Hyperbaric chamber

    33. RsCr 220 33 Head Hood

    34. RsCr 220 34 Head Hood Newborns only Watch for cooling

    35. RsCr 220 35 Pendant Reservoir

    36. RsCr 220 36 Reservoir Cannula

    37. RsCr 220 37

    38. RsCr 220 38 Nasal Biflow

    39. RsCr 220 39 Tracheal Catheter

    40. RsCr 220 40 Nasal Catheter

    41. RsCr 220 41 Oxygen (Croup) Tent

    42. RsCr 220 42 Croup Tent Can supply 30 to 50% oxygen

    43. RsCr 220 43 Incubator

    44. RsCr 220 44 Oxygen Blender

    45. RsCr 220 45 Functional Diagram of Blender

    46. RsCr 220 46 Blenders Found on all ventilators Easiest and most accurate way to deliver oxygen at precise percentages

    47. Even Less Commonly Used

    48. Hyperbaric Oxygen (High Pressure Oxygen) Monoplace Chamber Multiplace Chamber

    49. RsCr 220 49 Hyperbaric Oxygen Used to increase the amount of oxygen carried in the blood. HENRY’S LAW – the amount of gas dissolved in a liquid is directly related to the partial pressure of the gas(es) above the liquid.

    50. RsCr 220 50 Hyperbaric Oxygen Reduce the size of the air bubbles in the body Air Embolism Decompression sickness Boyle’s Law – Pressure and Volume are inversely related.

    51. RsCr 220 51 Indications for HBO Decompression sickness Diver with the ‘bends’ Gas Embolism Reduces the size of the bubbles Carbon monoxide and Cyanide poisoning Decreases half life of CO bond Severe anemia (blood loss) Wound healing Ischemic skin grafts, flaps, burns

    52. RsCr 220 52 Monoplace HBO Chamber

    53. RsCr 220 53 Hyperbaric Chambers

    54. Other Gases Carbogen Heliox Nitric Oxide

    55. RsCr 220 55 Carbogen Usually 95% oxygen and 5% carbon dioxide Treats singulitus (hiccups) Provides a challenge to stimulate breathing in some patients

    56. RsCr 220 56 Heliox Useful with ventilators and in ER Upper airway narrowing Croup Asthma Stridor Tracheal tumors The less dense gas is ideal for the tight passage through a narrow passage

    57. RsCr 220 57 Nitric Oxide Treatment of neonates with hypoxic respiratory failure associated with pulmonary hypertension A significant improvement has been noted with premature infants

    58. RsCr 220 58 Nitrous Oxide Used with anesthesia Don’t get confused between NO and N2O

    59. RsCr 220 59 That’s all folks
