GE Corometrics 120 Series Fetal Monitor Features

GE Corometrics 120 Series Fetal Monitor helps you manage the labor, delivery, and recovery process for every patient.

  • Our unique Spectra Alerts™ transforms the powerful 120 Series into a “Smart” monitor, complete with alert functions. This feature analyzes the fetal heart rate (FHR) and uterine activity (UA) patterns, as well as trend characteristics of variability, baseline, decelerations, and signal quality to assist the clinicians in evaluating the fetal strip.
  • Smart BP™, a patented feature that works in conjunction with DINAMAP® non-invasive blood pressure technology, automatically delays a blood pressure measurement while a contraction is in progress thus assuring more clinically significant assessment and documentation of the maternal status.
  • 3-Level-Heart Beat Coincidence (HBC) alerts the care provider with both visual and recorded messages when there is a possibility that you may be recording the same heart rate with two modes of monitoring. The monitor compares up to three heart rates and provides additional information for fetal assessment.
  • Fetal Pulse Oximetry (FSpO2) is an optional parameter that provides a real-time oxygen status of the fetus. In combination with other fetal parameters, FSpO2 helps in the early detection of fetal hypoxia and provides additional information in the presence of non-reassuring fetal heart rate patterns.
  • Integrated Masimo SET or Nellcor Maternal SpO2 make it easy for the clinician to monitor, document or even view the waveform
  • Maternal ECG SpO2 real-time 3-lead adult QRS waveform display and a snapshot printout.
  • Vital Signs History at a glance. Documents 8 hours of maternal parameters in the flowchart summary format…a time-saver during recovery.
  • The software upgrade, via PC or laptop computer, allows easy flash reprogramming as new features become available.
  • Expandability built-in. The system architecture allows for the addition of future parameters without purchasing a new unit.
  • High/Low Fetal Alarms notify clinicians if the fetal heart rate is out of the user-configurable range.
  • Selectable Font Size on the recording strip allows the font size to be adjusted quickly and easily(small, medium, or large) for optimum viewing efficiency.
  • Song Player serenades both mother and child to celebrate the new arrival. Three popular tunes are available with the turn of the Trim Knob®.
  • Our ChartLight allows the clinician to easily read the fetal strip, while patients remain relaxed in their low light setting
