Oxygenator Replacement - Terumo CAPIOX FX 25 Serie Instrucciones De Uso

3. Adjust blood flow rate, making sure that the blood level in the reservoir is adequate, to prevent gaseous emboli
passing to patient. (When using CAPIOX FX25 with Hardshell Reservoir, refer to Fig. 11, Page 10 "SAFETY MARGIN".)
4. For purging, open the purge line.
CAUTION Close purge line at termination of bypass.
5. Do not give any shocks to the product during perfusion.
e. TERMINATION OF BYPASS
Terminate extracorporeal circulation using normal procedure, taking note of the following warnings:
WARNINGS
• Before reducing blood flow rate, confirm that purge line is closed and the sampling line is also closed with
arterial side stopcock.
• On stopping pump, stop gas flow at once.
• If circulation is to be resumed, recirculation at a low flow rate is recommended. During recirculation, check
blood gas pressure. An excessive gas flow may cause low PaCO
f. OXYGENATOR REPLACEMENT
Always have a spare CAPIOX FX25 oxygenator for replacement if needed.
1. Set up and prime spare oxygenator module as described in SET-UP section. (page 7)
2. When necessary, maintain a decreased patient temperature as prescribed by physician.
3. Double-clamp blood inlet and outlet tubing connected to new oxygenator, and cut the tubing between the two clamps.
(See Fig. 8)
4. Stop circulation, double-clamp venous and arterial line connected to old oxygenator, and cut the lines between the
two clamps. (See Fig. 8)
5. Replace old oxygenator with new one by connecting venous and arterial line to the connectors at blood inlet and outlet
tubing of new oxygenator. (See Fig. 9)
CAUTIONS
• After replacement, open recirculation line for debubbling.
• Band and secure all connections in the circuit.
6. Start circulation at a low flow rate.
7. Connect gas lines removed from old oxygenator module to the new module and start gas supply.
8. Connect water lines removed from old oxygenator module to the new module and start water supply. Check for leaks.
9. Connect the purge line of the new oxygenator to the luer port leading to the cardiotomy filter.
10. Connect sampling line of new oxygenator to venous side connecting site of old reservoir. (See Fig. 10)

Volume in Reservoir (mL)
* Minimum operating blood level in CAPIOX FX25 Hardshell
Reservoir.
The above graph indicates the time in which the blood volume
in the reservoir decreases to minimum operating blood level
of 200 mL at each flow rate. If the blood volume in reservoir is
below 200 mL, bubbles may pass to the oxygenator module.
