Fetal Monitor Simulator

At week five, a fetus’ heart starts beating, increasing to 155 to 195 beats per minute prior to birth. The strength and number of beats can be measured by a fetal electronic monitor to determine whether a fetus is in distress. The PS320 fetal simulator mimics fetal and maternal heartbeats (ECG), along with uterine activity during labour to accurately test and troubleshoot fetal electronic monitors.


  • Mechanical heart for ultrasound simulation
  • TOCO simulation (External or IUP)
  • Ultrasound simulation (including twins)
  • Maternal ECG simulation
  • Fetal ECG (tracks ultrasound #1)
  • Internal (DECG) and external fetal ECG
  • Uterine-activity selections
  • Fetal beat-to-beat variability
  • Periodic and non-periodic fetal ECG changes
  • Arrhythmia selections
  • Compact, lightweight, pocket-sized plastic housing
  • Battery operated with status indications
  • Special kits available with all required accessories and cables to test fetal monitors for specified manufacturers

The PS320 simulates fetal and maternal ECG, as well as uterine activity, to test and troubleshoot fetal electronic monitors and to train clinical staff.

The unit is battery operated and small enough to fit in a pocket so mobile technicians and clinical instructors can take it anywhere. The PS320 is a fetal monitor simulator that provides several fetal parameters including twins, and it simulates a wide range of clinical scenarios for training labor-and-delivery staff in how to recognize normal and abnormal responses. An optional mechanical heart creates fetal heart sounds for testing fetal monitors’ ultrasound cables and transducers. The Fluke Biomedical PS320 offers an easy user interface providing a 2 x 16-character LCD display with adjustable contrast. The unit operates on a 9-volt battery with low-battery monitoring or functions with the supplied battery eliminator.
