PS320 Fetal Simulator

Introduction

The PS320 Fetal Simulator (hereafter called the
Simulator) is a compact, lightweight, high-performance
simulator for use by trained service technicians in fetal
monitor testing.

Cardiotocographs or Electronic Fetal Monitoring (EFM) is
a diagnostic tool used to identify a fetus at risk for
neurological injury or death. The trained clinician can then
carry out timely and appropriate intervention before the
underlying condition causes irreversible damage. The
goal of EFM is to detect fetal hypoxia at its earliest stage
and to attempt to prevent asphyxia resulting from
prolonged and severe hypoxia.

To gain a better overview of these clinical conditions,
please refer your available clinical references, or as a
suggested source, go to the Family Practice Notebook
website: http://www.fpnotebook.com. This website clearly
explains these clinical terms in Book: Obstetrics, Chapter:
Fetus, Page: Fetus Index.

The Simulator provides comprehensive simulation of fetal
and maternal ECG as well as uterine activity. It can
simulate several fetal parameters, including twins, via
such monitor modes as DECG and ultrasound. The
Simulator offers an easy user interface providing a 2 x 16­character LCD display with adjustable contrast.

Operating the MFH-1

The Mechanical Fetal Heart (MFH-1) is an accessory to
the Simulator. Connect the MFH-1 to the US 1 port on the
Simulator via the cable supplied with the MFH-1. Set the
rate and rhythm of the mechanical heart by adjusting the
US 1 output on the Simulator. For the MFH-1 to function,
you must power the Simulator through the Battery
Eliminator. The MFH-1 will not function on battery power.

Place the ultrasound transducer face up on your work
surface and coat it with an appropriate ultrasound
conductive gel. The MFH-1 outputs the mechanical signal
via the simulation window. Place this window over each

transducer crystal in turn to verify each crystal’s function.
