Helpful Hints and Recovery Procedures

Correcting an Incorrectly Entered Procedure

If you entered the wrong procedure type at the start of Prime mode,
perform the steps below before connecting the donor/patient.
If you installed the wrong disposable tubing set, before proceeding press
CHANGE MODE, then press 5 to select "Unload Set." Remove the
incorrect set and install the correct one.
1
Press CHANGE MODE. The following screen appears:
1=Load Set, 2=Prime, 3=Run, 4=Rinseback,
5=Unload Set, 6=Diagnostics.
Press 1.
2
The following screen appears:
Select set:
1=ELP, 2=TPE, 3=WBC, 4=RBCX
Press the number corresponding to the correct procedure, then
continue with Prime mode.
Note: If you chose the wrong procedure and have begun the Run,
press CHANGE MODE and choose RINSEBACK.

Using an Alternative Single-Pass Prime
Procedure
Follow the single-pass prime procedure when using saline containers that
have only one port. This procedure is an automated prime and de-
bubbling procedure which, rather than recirculating the prime saline,
sends the saline to a waste bag attached to the return saline line.
Also follow this procedure when hypersensitivity reactions associated
with ethylene oxide residuals (a by-product of sterilization) are a
concern.
For information on ethylene oxide sensitization, see Leitman SF et al.
Allergic reactions in healthy plateletpheresis donors caused by
sensitization to ethylene oxide gas, New England Journal of
Medicine,1986;5(19):1192-6.
Materials:
•
Disposable tubing set
•
Anticoagulant ACD-A
•
0.9% sodium chloride for injection (1000 to 2000 mL)
• One to two transfer bags (1000 mL each)
•
Sampling site coupler
Note: The Single-Needle ELP, LRS, and LRST procedures already
use a version of single-pass prime, automatically sending the
prime saline to the waste bag.
1
Prime the disposable tubing set as instructed for the apheresis
procedure, but DO NOT connect the return saline line to the saline
container.
2
Using aseptic technique, spike the sampling site coupler to a port on
the 1000 mL transfer bag.
