Indwelling Slit Catheter

WARNING: The Indwelling Slit Catheter procedure must not
exceed a 24-hour duration.
NOTE: ALWAYS start the procedure with a full syringe.
1. Perform steps 1 through 7 of the Quick Pressure Monitor Set
instructions.
2. Remove the needle from the monitor.
3. Attach the slit catheter to the tapered chamber stem. Make sure
the fit is very snug. See Figure 4.
NOTE: Optional extension tubing may be used between the slit
catheter and the monitor if additional length is desired.
4. Remove the needle guard from the break-away needle, and push
the catheter in until it is just visible at the end of the needle.
CAUTION: DO NOT let the catheter protrude from the needle, as it
may be cut by the needle upon insertion.
5. Hold the needle approximately 45 degrees up from horizontal.
Slowly force fluid through the disposable to purge it of air.
6. Bring the catheter tip (slit end) to the same height as the
disposable diaphragm. See Figure 5. The display should read -8
to +9 mmHg.

WARNING: To ensure accuracy, the device must be at the
correct angle of insertion (with the disposable diaphragm at
the same height as the catheter tip) before the ZERO button is
pressed.
7. Press the ZERO button.
NOTE: The display must read "00" before continuing. If the display
does not read "00," see the Troubleshooting section.
WARNING: DO NOT use the pressure readings when the
display indicates low battery. Replace the battery (see the
Battery Replacement section) and repeat the steps to obtain
the pressure reading.
8. Hold the catheter and the needle together and push into the
compartment. Make sure the catheter's tip is protected inside the
needle.
9. Push the catheter forward while pulling back on the needle. See
Figure 6. Tape the catheter in place after the needle is out of the
skin.
10. Remove the break-away needle.
NOTE: Pinch together the green fins on the needle, then pull the fins
apart and split the needle away. See Figure 7.
11. Keep the chamber in the monitor at the same height as the
estimated height of the slit tip of the catheter in the body. See
Suggested Set-Up for the Pressure Monitor with Indwelling Slit
Catheter Set section.
WARNING: The monitor must be securely taped to the patient
to prevent its displacement and/or patient injury.
12. Inject less than 3/10 mL of saline into the compartment to
equilibrate with interstitial fluids.
13. Wait for the display to reach equilibrium.
14. Record the pressure readings at the appropriate intervals. Repeat
step 12 to ensure patency for subsequent measurements.
