Priming And Recirculation Procedure - dideco D 905 EOS Bedienungsanleitung

CAUTION
Remove the plastic insert only after connecting the venous tub-
ing to the venous return connector.
ASPIRATION LINES:
Without separation of blood recovered by the aspirators:
after removing protective caps from the "filtered" inlet connec-
tors on the top of the Cardiotomy Reservoir (four 1/4" / 6,35 mm
connectors, two 3/8" / 9.53 mm connectors), connect the aspi-
ration lines and rotate the turrets (fig.2, ref.6) towards the suc-
tion pumps.
With separation of blood recovered by the aspirators:
connect the two "Y" adapters found in the convenience kit to the
two connectors on the top of the Cardiotomy ("Cardiotomy
Bypass Port", (fig.2, ref. 15)). Connect to the inlets of the two
adapters (four 1/4" / 6,35 mm inlets, two Luer lock inlets) any
lines that should connect directly to the Venous Reservoir: ven-
tricular aspirators, aortic root aspirator, arterial filter drainage,
blood concentrator, Venous Reservoir quick-priming. Finally,
connect the remaining suction lines to the filtered inlets on the
Cardiotomy Reservoir (fig.2, ref. 6). During the entire proce-
dure, keep the connection key (fig.2, ref. 3) closed (positioned
at the bottom).
ARTERIAL LINE: remove the red cap on the oxygenator arterial
outlet indicated as "ARTERIAL OUTLET" (fig.2, ref.5) and con-
nect a 3/8" line.
PUMP LINE: the pump segment should be set up between the
Venous Reservoir outlet connector (fig.2, ref.7) and the oxy-
genator venous inlet connector (fig.2, ref.4) taking account of
the direction of rotation of the pump.
CAUTION
If oxygenated blood is necessary for blood cardioplegia,
remove the red pos lock and connect the 1/4" blood line of the
cardioplegia circuit to the D 905 EOS coronary outlet port
using the D523C reducer (provided with the product).
The coronary outlet port has a self-sealing valve which allows
connection of the D 523C reducer also during extracorporeal
bypass without any leakage or spillage of fluid.
WARNING
If a connection is made to the coronary outlet port during
bypass, the line to be connected must be unclamped and
unpressurised such that blood will flow into it upon connec-
tion.
6) SAMPLING RAMP
The arterial/venous sampling ramp is supplied in a single steril-
ity bag integrated with about 1 m venous/arterial tubing lines.
ARTERIAL SAMPLING LINE: remove the protective cap from the
luer connector placed beside the arterial outlet (fig.2, ref. 8).
Connect the male luer of the arterial sampling line of the ramp.
WARNING
Male luers not supplied with SORIN GROUP ITALIA products
may damage the one-way valve placed inside the oxygenator
arterial sampling luer. When connecting, make a visual check
that the male luer does not reach as far as the one-way valve.
VENOUS SAMPLING LINE: remove the protective cap from the
luer connector placed beside the venous inlet (fig.2, ref. 14).
Connect the male luer of the venous sampling line of the ramp.
7) CONNECT THE TEMPERATURE PROBES
The connection for the arterial temperature probe (red - fig.2,
ref.9) is positioned next to the arterial outlet, while the venous
probe site (blue - fig.2, ref.10) is at the side of the venous inlet.
SORIN GROUP ITALIA temperature probes have the code
09026.
8) CLOSE THE PURGING/RECIRCULATION LINE
Close the purging-recirculation stopcock (refer to the diagram
on the label).
9) CONNECT THE GAS LINE
Remove the green cap from the gas inlet connector indicated as
"GAS INLET" (fig.2, ref.11) and connect the 1/4" gas line.
Ensure that the gas supply is from a suitable air/oxygen mixer
such as the Bird, code 09374 (available from SORIN GROUP
ITALIA) or a system with compatible technical features. A
capnograph connector can be found in the centre of "GAS
ESCAPE" (fig.2, ref.12) connector.
WARNING
- The "GAS ESCAPE" system is designed to avoid any possi-
ble risk of blocking the gas outlet; such blockage could
cause the immediate passage of air to the blood compart-
ment.
- SORIN GROUP ITALIA recommends the use of a bubble trap
or filter on the arterial line to reduce the risk of emboli
transmission to the patient.
10) VAPOROUS ANAESTHESTICS
The oxygenator is suitable for use with volatile anaesthetic iso-
flurane and sevoflurane, by mean of a suitable narcosis gas eva-
porator.
If these vaporous anaesthetics are used, some method of sca-
venging the gas from the oxygenator should be considered.
The protocol, the concentration and the monitoring of the anae-
sthetic gases administrated to the patient, is under the sole
responsibility of the physician in charge of the treatment.
WARNING
The only volatile anaesthetics suitable for this use are isofluora-
ne and sevolfuorane
WARNING
The methods adopted for vaporous anaesthetic gas scavenging
should not increase or reduce in any way the pressure level at the
oxygenator fibres.
F. PRIMING AND RECIRCULATION PROCEDURE
WARNING
Do not use alcoholic priming solutions: such solutions could com-
promise the proper function of the oxygenating module.
1) KEEP THE GAS FLOW OFF
2) KEEP THE OXYGENATOR PURGING/RECIRCULATION LINE
CLOSED
Check that the purging-recirculation stopcock is closed.
3) CLOSE VENOUS AND ARTERIAL LINES
Clamp the venous line. Clamp the arterial line some centimetres
away from arterial outlet connector of the oxygenator.
4) CHECK THE HEAT EXCHANGER
Verify again the integrity of the heat exchanger, paying particu-
lar attention to possible water leaks.
5) VENOUS RESERVOIR PRIMING
Secure with ties all aspiration lines connected to the Cardiotomy
Reservoir. Fill the Cardiotomy Reservoir through the "Quick
Priming Port" (fig.2, Ref. 16) with sufficient liquid to ensure the
intended haematocrit is obtained, taking into account:
- the static priming volume of the oxygenator is 160 ml;
- the 3/8" tube capacity is 72 ml/m;
- the 1/2" tube capacity is 127 ml/m.
Clamp the Venous Reservoir outlet.
In order to fill the Venous Reservoir or if the Cardiotomy
Reservoir capacity (1200 mls) is not enough, open the connec-
tion to the Venous Reservoir by raising the connection key
(fig.2, ref.3) on the top of the Cardiotomy Reservoir.
