Post-op
The postoperative Post-op protocol is intended to concentrate, wash, and collect the blood drained
from a surgical cavity of a patient in a postoperative context.
If the X
VAC
vacuum module is present while Post-op is the active protocol, it will provide a negative
pressure in the cardiotomy suitable for the drainage from the surgical cavity of the patient.
To avoid the risk of moving air toward the patient, it is not possible to activate the Return function
while the Post-op protocol is active.
The Post-op protocol uses the same procedure as the Popt protocol, except that the vacuum pump
works in the postoperative mode (refer to
Chapter 13: Vacuum Module
).
Fill, Wash, and Empty Phases
The execution steps of the Fill, Wash, and Empty phases are identical to those of the Popt protocol
(refer to “Popt” on page 5-24).
Note: Verify that the X
VAC
vacuum pump is set to the POST-OP mode when collecting blood
postoperatively.
CAUTION
Inadequate washing of concentrated red blood cells can lead to an excessive
level of contaminants (i.e. anticoagulants and plasma free hemoglobin) in the
treated blood.
CAUTION
Use of the vacuum pump in INTRA mode while collecting blood
postoperatively might expose the patient to risks of tissue damage
CAUTION
As soon as postoperative drainage operations are completed, the patient
must be disconnected from the reservoir.
CAUTION
The use of protocols different from POST-OP in postoperative contexts might
expose the patient to risks of tissue damage due to high aspiration levels of
vacuum module and risks of blood return due to availability of the return
function.
CAUTION
During setup and unload of the kit, the patient must not be connected to the
reservoir through the drainage line.
CAUTION
The availability of alarms does not relieve the operator of his or her obligation
to carefully monitor the entire system during operation. Unattended
processing can lead to the development of problems with the operation of the
system and/or with the quality of the end product.
CAUTION
In the case of malfunction of the integrated vacuum pump, use an alternative
vacuum source, i.e., the vacuum present in the operating room, possibly
connected to a pressure regulator.
