GE Corometrics 259 Features

The GE Corometrics 259 is a maternal/fetal monitoring system. This unit is a full antepartum/intrapartum fetal monitor that includes innovative features that help clinicians deliver a high-quality birthing experience and enhanced patient care. The Corometrics 259 monitors uterine and fetal activity including fetal heart rate, and has enhanced maternal monitoring features including temperature, oxygen saturation, ECG, and non-invasive blood pressure. The 259 provides a comprehensive perinatal monitoring and the flexibility and convenience that give you instant access to the detailed information you need during labor and delivery. Having that information readily available helps you provide a positing birthing experience for the mother and baby.

The Corometrics 259 is a medical device for monitoring maternal/fetal parameters. This monitor is equipped with a color LCD display which provides simultaneous display of fetal and maternal parameters plus the maternal waveforms. On the right side of the front of the unit is the recorder. The recorder prints continuous trends and alphanumeric data on one strip chart. The system is compatible with Centricity Perinatal Clinical Information Systems and other information systems to streamline, capture, and archive patient data. The 259 supports two fetal heart rate (FHR) channels, Uterine Activity (TOCO or IUP), maternal non-invasive blood pressure (NIBP), maternal pulse oximetry (MSpO2), fetal ECG (FECG), and Maternal ECG (MECG).

On the back of the unit there are many data ports for inputting and outputting data and power. You have a Telemetry Connector, Data Entry Connector, Nurse Call System, Central Systems Connector, External VGA Connector, Communication Connectors, ECG Out Connector, Fetal Acoustic Stimulator Connector, Remote Event Marker Connector, and a Power Inlet Module.

When powering up the Corometrics 259 Fetal Monitor, the unit automatically performs a number of tests to verify the integrity of the system memory, processor, and voltage levels before allowing the monitor to enter a normal operation mode. The pulse oximetry module is also tested and automatically calibrated upon power up, or whenever the unit is reset.

General Information on Fetal Monitors

Fetal Monitoring
Fetal monitoring is extensively used in birthing facilities for measuring fetal well being and assessing labor progress. Electronic Fetal Monitors are used to detect and trace the fetal heart rate and uterine contractions. These are usually monitored at the same time however, each one can be obtained separately.

Terminology used for Fetal Monitors

  • Ultrasound(U/S Transducer): A transducer is placed on the abdomen to direct an ultrasonic beam towards the fetal heart and to sense Doppler-shifted echoes created by moving cardiac structures.
  • Uterine Activity(Toco or U/A Transducer): Uterine contractions are recorded from a pressure-sensitive device that is placed on the abdomen and held by a lightweight stretchable band or belt.

Different features in Fetal Monitors

  • Monitoring Modes:
    • Antepartum: occurring or existing before birth; "the prenatal period”.
      • Parameters to be considered:
        • Fetal Heart Rate(U/S)
        • Uterine Activity(U/A)
    • Intrapartum: Occurring during labor and delivery.
      • Parameters to be considered:
        • Fetal ECG
        • Intrauterine Pressure Catheter (IUPC)
