((FFDD22))
Obstetric mode is automatically selected when
an obstetric probe (OP2HS/OP3HS) is
connected. Fetal Heart Rate (FHR) is displayed
with 3 operating modes, and an RS232
interface provides for FHR printing when
connected to the Dopplex Printa Package.

((FFDD11//FFDD33))
Operates in standard mode to provide FHR
display. The probe/cable are waterproof and
can be fully immersed for use in waterbirths.
The FD1/FD3 main unit is not water-
proof and must not be immersed.

Apply a liberal amount of gel to the abdomen.
Place the faceplate of the probe flat against
the abdomen above the symphysis pubis.
Adjust the probe to obtain an optimum audio
signal ideally by angling the probe around.
Avoid sliding it over the skin.
In early pregnancy a full bladder may improve
sound detection. In later pregnancy the best
signals are generally located higher on the
abdomen. The fetal heart sounds like a
galloping horse at approximately twice the
maternal rate. A wind-like sound is heard from
the placenta.

FFDD11//FFDD22//FFDD33
In this mode the FHR, averaged over 4-heart
beats, is displayed on the 3-digit readout.
This gives FHR performance similar to
conventional fetal monitors. The LCD displays
an outline heart symbol.

This mode is used to obtain more stable heart
rate readings. In this mode, FHR is averaged
over 8 beats. The LCD displays a solid heart
symbol.

FFDD22
OOnnllyy
This mode is used when a fetal heart beat is
audible in the loudspeaker or headphones but,
due to noise or a low signal level, the
FFDD22
cannot reliably calculate the heart rate. In this
mode, the heart rate can be manually counted
over a period of 10 audible heart beats (see
below). The
FFDD22
will automatically calculate
and display the derived FHR on the LCD. The
LCD displays a clock symbol.

The
FD2
will select vascular mode when
a vascular probe is connected to the
control unit.
In this mode, blood flow is audible in the
loudspeaker. Probe frequency is
displayed.
Clinical
Use
Apply a liberal amount of gel on the site
to be examined. Place the probe at 45° to
the skin surface over the vessel to be
examined. Adjust the position of the
probe to obtain the loudest audio signal.
High pitched pulsatile sounds are emitted
from arteries while veins emit a non-
pulsatile sound similar to a rushing wind.
For best results, keep the probe as still as
possible once the optimum position has
been found. Adjust the audio volume as
required.
Probes
Five probes are available for vascular
examinations:
VP4HS
4MHz ±1% for deep
lying vessels
VP5HS
5MHz ±1% for deep
lying vessels and
oedematous limbs
VP8HS
8MHz ±1% for
peripheral vessels
VP10HS
10MHz ±1% for
specialist
superficial applications.
EZ8
8MHZ ±1%
"Widebeam" for
peripheral vessels.
