Quick Start
Laborie NXT Pro Owner’s Manual LBL-00146 [C], MAN2010 30
Fill a 10 cc syringe and attach it to the side Luer-Lok of the stopcock. Hold the
catheter so that the balloon is pointing upward.
a. For the dual-lumen catheter, infuse solution from the filled syringe into
the catheter to force the air inside the catheter to ascend then discharge
out of the purge lumen. After all air has been removed from the catheter,
close the Luer-Lok cap on the purge lumen. Collapse the balloon by
withdrawing the fluid from the catheter with the syringe.
b. For a single-lumen catheter, ensure to fill a 10 cc syringe with 5 cc to 7 cc
of solution. Hold the catheter so that the balloon is higher than the
stopcock. Open the stopcock to the syringe and the catheter and aspirate
all air from the balloon. Infuse 4 cc to 5 cc of solution into the catheter to
slightly distend the balloon. Repeat aspiration and infusion until no air
remains in the balloon.
Finish preparation with the balloon collapsed and the stopcock off to all Luer-Loks.
Apply a light film of water-based lubricant to the balloon and insert the catheter.
For female patients: Insert the Abdominal Fluid NXT catheter into the rectum
10 cm to 15 cm, past any stool that may be present, along the anterior wall of the
rectum. Alternatively, insert vaginally in the posterior fornix, just behind the
cervix, at the level of the cul-de-sac of Douglas.
For male patients: Insert the Abdominal Fluid NXT catheter into the rectum
10 cm to 15 cm, above the prostate, past any stool that may be present, along
the anterior wall of the rectum.
Open the stopcock to the syringe and the catheter and infuse approximately 1 cc
to 1.5 cc of solution.
Slowly open the stopcock to the Luer-Lok where the pressure measurement tubing
will be attached. Connect the tubing to the stopcock as the meniscus forms on the
stopcock Luer-Lok. Take care not to lose fluid from the catheter.
At the beginning of the study, the abdominal pressure must equal vesicle pressure
in Synergy. If Pabd is higher than Pves, slowly open the stopcock to the free luer
connector and allow a drop of solution to escape. Repeat until Pabd equals Pves. If
Pabd is lower than Pves, open the stopcock to all Luer-Loks and use the syringe to
add a few drops of solution. When Pves and Pabd are equal, Pdet will be 0 cmH20.
Turn the stopcock off to the syringe and instruct the patient to cough to verify
continuity and pressure transmission.
2.6.2.5 Confirming Catheter Placement
Manually confirm catheter placement or use the automated Quality Check feature through
the Synergy user interface.
To manually confirm catheter placement using the Synergy user interface, perform the
following instructions:
Ensure that all pressure catheters are inserted into the patient and appear in the
Synergy Consumable Traceability panel during the Preview phase.
During the preview phase, ask the patient to cough.
When recording two pressures at the same time, the cough will show equal
deflection on both channels (
Figure 16). With Auto Cough detection activated,
Synergy will automatically mark these deflections as coughs. For more
information, refer to the section Customizing Control Panel on page 61
