Starting the System
Before using the OptoMonitor 3 and OptoWire, read the Instructions for Use accompanying the
product.
NOTE:
A warm up period (approximately 20 minutes) before the dPR or FFR procedure is
recommended.
1.
Press the POWER switch, located on the underside of the unit, towards the right side of the
device.
2.
A single medium tone will sound from the DU, and the OpSens logo will appear.
Wait until the MAIN menu is displayed and fully loaded (approx. 10 seconds).
Verifying Optimal Aortic Pressure Waveform and ensuring Pa Zero
Using Aortic Input from Cathlab Hemodynamic System
1-
Perform aortic input calibration of the Cathlab Hemodynamic System (via steps outlined in
section 8.3.2)
2-
As per standard procedure, open aortic pressure transducer line to air by properly positioning
stopcock valve and ensure hemodynamic system 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 has been zeroed successfully, continue to section
7.3 Connect the OptoWire Cable FOIC Connector
The OptoMonitor 3 is intended to be used with OpSens’ pressure guidewire devices.
OpSens’ pressure guidewire devices are available in two different models:
Pressure devices WITH Gauge Factor Connector (device label indication).
Pressure devices WITHOUT Gauge Factor Connector (device label indication).
NOTE:
•
Sensor calibration information of pressure guidewire
WITHOUT
Gauge Factor Connector
is contained within the OptoWire cable and does not need a Gauge Factor Connector.
•
Sensor calibration information of pressure guidewire
WITH
Gauge Factor Connector is
contained within Gauge Factor Connector.
