Preparation of IUP Transducer:
Plug the yellow IUP transducer connector into the yellow socket labelled IUP on the
front panel of the FETATRACK 360.
Because there are several alternative designs of IUP transducer which may be used
with the FETATRACK 360 it is necessary to consult the specific instructions
supplied with the transducer. If using an external transducer with fluid-filled
coupling the system must be flushed and primed to remove air bubbles prior to use.
The relative UA zero may be set by pressing the front panel UA0 control.
Note: The zero setting may drift slightly until the entire system is at room
temperature.
Proceed with Monitoring:
Turn the printer on and check whether the UA recording is adequate.
Note: Since the pressure should never read below zero, this would be considered a
fault condition and the Front Panel UA Digital Display will flash "0". If such a
condition develops, check the catheter connections and repeat the UA zero
procedures. If the transducer becomes unplugged, the UA Display will show " - - - "
indicating there is no UA input.
Between the contractions the UA channel will not return to zero. This is the measure
of the uterine resting tone.
If, during monitoring, the UA channel does not appear to be accurately plotting
contractions or the tracing of the contractions looks "sluggish", you should suspect
the catheter tip has either collected debris from the amniotic fluid or contains air
bubbles, depending on the type in use. Follow the manufacturer's instructions to
clear any obstruction and continue recording.
To check that the system is operational, it is often helpful to ask the patient to cough
which should produce an artifact on the strip chart record.
