Using Aortic Input from the Aortic Transducer (Use with BP-22 compatible transducer)
1-
Perform aortic input calibration of the aortic transducer (via steps outlined in section 8.3.1)
2-
As per standard procedure, open aortic pressure transducer line to air by properly positioning
stopcock valve and ensure transducer aortic pressure (Pa) is properly zeroed.
3-
The guiding catheter should be frequently flushed with normal saline to ensure an optimal aortic
pressure waveform (without oscillation or damping) is obtained.
4-
Ensure the Pa displayed on Display Unit (DU) is equal to zero (0) before continuing.
If Pa
displayed on DU is not equal to Zero, press the Zero button to perform an AO zero adjustment.
5-
AO zero has been completed when the message “Aortic Zero successful” appears in the message
window, display shows
ø
AO
in the top left-hand corner and the Pa on the Display Unit shows
“0”. Once performed successfully, proceed to step
7.3 Connect the OptoWire Cable FOIC
Connector to the OptoMonitor 3 Handle
If the AO Zero failed, the message”
Aortic zero failed!
” is shown. Verify that the AO is open to air, all
connections properly established and press the AO Zero button again. In the case where AO has been
zeroed once, and a zero value is stored in the memory, the message “
Aortic zero failed, old value used”.
NOTE:
The BP-22 compatible transducer is not supplied with the OPM3 system.
Connect the OptoWire Cable FOIC Connector to the OptoMonitor 3 Handle Unit
1.
Leave the OptoWire in the tray
2.
Place the tray flat on the table
3.
Connect the FOIC connector (green) into the Handle Unit
4.
For Pressure Guidewire device model
WITHOUT
Gauge Factor Connector, proceed to section
Zeroing OptoWire to Atmosphere
5.
For Pressure Guidewire device model
WITH
Gauge Factor Connector, insert the matching Gauge
Factor Connector into the Handle Unit narrow opening beside the LED indicator. Orientation is
not important.
GFC
NOTE:
The OptoWire is not supplied with the OpM3 System.
WARNINGS:
•
Use only the corresponding pressure guidewire Gauge Factor Connector and OptoWire
Cable supplied in the same tray.
•
The use of mismatched Gauge Factor Connector and OptoWire cable with pressure
guidewire will affect the measurement accuracy.
1.
Press the AO Zero button on the MAIN screen.
2.
A warning message will appear, warning the user to ensure transducer zero has been
performed.
3.
Press the “YES” button if the transducer zero has been performed on the aortic pressure
channel.
4.
Press the “NO” button if the transducer zero has not been performed on the aortic pressure
channel.
Proceed with transducer aortic channel zero and check the DU for zeroing again. Repeat from
step 1 if still not zeroed.
