The flashcards below were created by user jean38112 on FreezingBlue Flashcards. What would you like to do?


  1. to maintain artery access we use what?
    guidewires
  2. the length of guidewires
    length ranges from 35-360cm

    the average is 150-180 cm
  3. diameter of guidewires include?
    diameter ranges from .012-.038 cm

    • normal diagnostic: .035-.038 cm
    • balloon intervention: .012-.018cm
  4. 4 types of guidewire include?
    • J-wire
    • angled
    • straight
    • movable core
  5. J-wire
    • most commonly used
    • 3.0 mm for cardiac procedures

    deflects vessels, decrease risk of perforation, easy to position or change direction of tip

    avoids sm branches, won't fit into equipment
  6. angled wire
    • tip has angle
    • for peripherals
    • has more pushability and strength
    • don't deflect as much, it's directional and likes to find small branches
    • increased perforation risk, tends to enter sm branches,
  7. straight wire or floppy wire
    • very soft and flexible, great tracking
    • "floppy" straights
    • it fits in tight spaces
    • high perforation risk
    • can go off track, likes small vessels
    • used on exchange wires
  8. movable core
    • the mandral can retract
    • high risk for perforation if core is not relaxed when entering into vessel
  9. 2 types of coating for guidewires
    • teflon
    • polythylene-hydrophilic
  10. teflon coating
    • slick feeling, non stick
    • has ridges
    • for cardiac procedures
    • never leave in body for longer than 3-5 min
  11. polythylene
    • plastic coating
    • peripheral work
    • stays wet and slippery
    • "snot" wire
    • NEVER PUT CATH THRU THIS WIRE!!! IT WILL SCRAPE PLASTIC OFF AND ADVANCE INTO ARTERY
  12. sheaths
    decreases bleeding and increase speed of procedure

    they are color coded, very important for length and diameter

    used to dilate arterial hole so sheath can fit through them
  13. what are sheath sizes measured in?
    french

    each french is 1/3 of a mm
  14. color codes for sheaths
    • 4f red
    • 5f gray
    • 6f green
    • 7f orange
    • 8f blue
    • 9f black
    • 10f purple
    • 11f yellow
  15. length of sheaths are?
    • 5-25 cm
    • 5cm for child/infant/radial
    • 25 for thicker pt/tortuous vessels/tighter vessels

    average 11-12cm for groin and brachial
