  1. what are the limits of dextrose and amino acids in a peripheral line for PN
    • dextrose - < 10%
    • AA 2.5-5%
  2. dwell time for a peripheral venous access device
    72 hours
  3. dwell time of a midline catheter
    1-6 weeks
  4. 4 types of central venous access devices
    • PICC - peripherally inserted central catheter
    • non-tunneled
    • tunneled
    • implantable ports
  5. characteristics of intermittent infusions - 4
    • over 30min - 1 hour
    • specific intervals
    •   q6,8,12 h
    • 50 - 100 mL (SVPs)
    • via primary line
  6. characteristics of continuous infusion 4
    • large volume parenterals
    • over several hours or days
    • slow and constant rate
    • gravity infused or using infusion control device
  7. 4 dependents for infusion by gravity
    • pressure and resistance from
    •   volume of fluid being infused
    •   viscosity of solution
    •   admin set/tubing length and diameter
    •   pt position and activity
  8. gravity driven controllers 5
    • flow rates between >5mL/hr & <200mL/hr
    • only useful when pressures less than 50mmHg are required
    • compensates for
    •   patient position or activity
    •   IV fluid volumetric changes
    •   temp-related changes in viscosity
  9. ICD's: positive pressure pumps
    • more accurate & accommodate very slow rates
    • increase pressure = increase rate of I infiltration and tissue damage
  10. 5 ICD positive pressure pump systems
    • peristaltic pump
    • cassette pumps
    • syringe pumps
    • non-electric pumps (elastomeric)
    • implantable pumps
  11. limitation of syringe pumps
    volumes of 1-60mL
  12. implantable pump capacities
    15,30,50 mL
  13. advantages of peristaltic pump 3
    • simple to use
    • inexpensive
    • can use standard IV sets
  14. disadvantages of peristaltic pump 1
    distortion of tubing may reduce flow rate accuracty
  15. advantages of cassette pumps 1
    good flow rate accuracty
  16. disadvantages of cassette pumps 1
    more expensive and require specialty IV sets
  17. advantages of syringe pumps 4
    • good flow rate
    • good flow continuity
    • generally small, lightweight & portable
  18. disadvantages of syringe pumps 2
    • volume of continuous infusion limited to 60mL
    • power source can be limiting
  19. advantages of nonelectronic pumps 3
    • small, portable, lightweight and inconspicuous
    • inexpensive
    • can be prefilled or frozen
  20. disadvantages of noneletronic pumps 3
    • limited range of volumes
    • limited flow rates
    • can't be reused or recycled
