11. HEPARIN DELIVERY
11.1 OVERVIEW
Heparin is a chemical that prevents the natural clotting of blood in
the extracorporeal circuit. The Arena Instrument can
automatically infuse heparin into this circuit at an operator-
adjustable rate using a heparin pump.
11.1.1 Customization
A qualified service technician can customize the heparin pump for:
•
•
Maximum Heparin Bolus Limit
The maximum limit is adjustable from 1.0 to 5.0 mL in 1.0 mL
increments. Refer to Section 17.3.1.5. The operator will be able to
set the bolus volume from 0.3 mL to this maximum value.
Syringe Size
Sizes allowed are 10 mL, 12 mL, 20 mL or custom capacity
syringes. Refer to Section 17.3.1.4. The heparin pump plunger
foot must be changed accordingly to switch from a 10/20 to a
20/30 mL syringe or vice versa. See Table 11-1 for a list of the
most common syringes and their sizes. B-D’s 10 and 20 cc, and
Monoject’s 12 and 20 cc syringes can be selected directly in
Calibration Mode. Other sizes can also be selected using the
custom diameter selection.
