Vascular Access Device
● Tube inserted into a vein or artery
● Ready access to the patient’s circulation
●Eliminating multiple phlebotomies Uses:
1.Administer fluids or medication
2. Draw blood
3. Central venous pressure reading
● Specialized personnel
● Never apply torniquet or perform venipuncture
on an arm w/VAD
A-line or Art-line
Arterial line
Administering medication
3.Heparin or Saline lock
Hep lock
catheter that is placed in an artery
Arterial line
most commonly placed in a radial artery
Arterial line
drawing blood

3.Heparin or Saline lock
Hep lock
Thin plastic tube or catheter
4.Intravenous (IV) Sites
can be left in place for up to 48 hours
3.Heparin or Saline lock
Hep lock
inserted in a vein to administer fluids
4.Intravenous (IV) Sites
blood specimens can be contaminated or diluted with
the IV fluid, causing erroneous test result
○ Draw blood below the IV site
4.Intravenous (IV) Sites
IV in one arm: Collect blood from the other arm
4.Intravenous (IV) Sites
flushed with heparin or saline to keep it from clotting
3.Heparin or Saline lock
Hep lock
5-mL discard tube should be drawn first
3.Heparin or Saline lock
Hep lock
Drawing coagulation specimens is not recommended
3.Heparin or Saline lock
Hep lock
IVs in both arms or the other arm is unavailable?
collect by capillary puncture
4.Intravenous (IV) Sites
Only specially trained personnel
