  1. 4 examples of high flow o2 delivery devices
    • venturi
    • aerosol
    • t piece (briggs adapter)
    • face tent
    • tracheostomy collar
  2. primary benefit of using a reservoir cannula
    conserves o2 by storing it in the reservoir
  3. list 3 vent cireteria that should be met by pts reveiving o2 from a low flow device
    • consistent vent pattern
    • vt 300-700
    • rr less than 25
  4. give 3 examples of low flow o2 delivery devices
    • nasal cannula
    • simple o2
    • partial rebreathing
  5. list conditions that affect the accuracy of pulse oximeter
    • poor perfusion
    • severe anemia

    • cyanide poisoning
    • decompression sickness
    • gas gangrene
    • gas embolism
  7. how does water in the aerosol tubing of a mask affect the delivered FIO2
    increases fio2
  8. dr orders o2 therapy for a pt with a VT of 400 ml and an inspiratory time of .5 s. what flow must the mask deliver to meet this pt's ins flow demans
