Corometrics* monitors feature innovative technologies for accurate data:

Innovative Corometrics* 9-Crystal Ultrasound

  • 9-crystal pulsed Doppler design

  • A wider focal region than traditional 7-crystal designs for more uniform coverage at greater depths

  • Helps ensure minimal repositioning, even for the most difficult to monitor patients

  • Signal consistency/uniformity signal as labour progresses

  • Quick FHR detection

Independent Volume Control for twins

  • Accurate placement of second ultrasound transducer

  • Listen to both foetal heart rates at the same time with limited risk of confusion

  • Also valuable for differentiating singleton heart rate from maternal

FHR Offset for better twin management

  • Helps differentiate between the three potential heart rates

  • Compares single foetal heart rate with maternal heart rate

  • Immediate notification of confusion on display, paper strip and independent volume control

GE Dinamap* NIBP algorithm1

  • Patented SuperSTAT* technology for great reliability

    • Speeds up determinations: reduction of an average determination time 

    • Enhances patient comfort

  • Smart BP*

    • Delays blood pressure measurement during contractions

    • Helps reduce patient distraction

    • Offers meaningful diagnostic data

  • Adult long BP cuffs

    • Offers extra comfort for larger mothers

Optional Maternal Temperature

  • Temperature moderating in labour serves to detect possible infection and avoid the potential harmful effects of hyperthermia

  • Innovative temperature assessment requires only a light stroke across the forehead

  • Based on infrared readings of temporal artery blood flow


Enjoy a large selection of exceptional parameters in one device: external and internal foetal parameters with maternal parameters as an option.
