AngioDynamics C3 WAVE SYSTEM Gebrauchsanweisung Seite 7

Warning: Ensure that the stylet tip does not extend beyond the
trimmed end of the catheter. Extension of the stylet tip beyond
the catheter end combined with kinking and excessive forces
may result in vessel damage, stylet damage, difficult removal,
stylet tip separation, potential embolism and risk patient injury.
D. Attach saline-filled syringe and flush catheter.
E. Remove the syringe after flushing.
6. Catheter Insertion
A. Perform ultrasound and locate vessel. Follow ultrasound system
Instructions for Use.
B. Follow catheter Instructions for Use regarding Venous Access
and Catheter Insertion.
C. Connect the end of the ECG Clip Cable (provided in the ECG
Cable Accessory Pack) through the drape window to the ECG
patient hub.
Note: C3 Wave only works with conductive [metal] stylets.
- Secure the ECG Clip Cable (alligator clamp) to the proximal
end of the stylet.
D. Place C3 Wave System monitor in 'Internal Mode' and insert
catheter per manufacturer's Instructions for Use.
E. Flush catheter with saline and wait for intravascular ECG
waveform to stabilize on monitor screen.
F. Verify that the P-wave on the intravascular ECG waveform is
present, identifiable, and consistent on monitor screen.
Warning: Do not rely on ECG signal detection for Catheter tip
positioning when interpretation of the P-wave is difficult. For
example, when:
a. P-wave is not present
b. P-wave is not identifiable
c. P-wave is intermittent
7. Catheter Tip Guidance and Positioning
The following figures show approximate catheter tip positions and
representative intravascular ECG waveforms.
Figure 1: No evident P wave change - catheter tip is not in an
acceptable position.
Figure 2: P wave at its maximum height - catheter tip is in the lower
1/3 of superior vena cava/right atrial junction.
Figure 3: Downward deflection on the leading edge of the P wave -
catheter tip is entering the right atrium.
Figure 4: Biphasic P wave – catheter tip is within the right atrium.
Figure 5: Inverted P wave - catheter tip is approaching the right
ventricle.
