GE 118 Corometrics fetal Monitor

The Corometrics 118 Fetal Monitor is a twin capable unit that includes one toco and two ultrasound transducers, fetal EKG, event marker and a chart recorder. Data storage and transmission Integrated Maternal Pulse Oximetry NIBP. Extends upon the advanced technology of the Model 116 with integrated maternal pulse oximetry and/or noninvasive blood pressure monitoring.

Features
Easy operation
Intuitive controls and menus
Simplified operation of all functions
Controls are tailored for labor and delivery to make operation user friendly
Visual/Audible Maternal Alarms
The unit provides visual and audible alarms when maternal SpO2, NIBP or pulse rate values exceed user-defined high/low limits
Audible alarms can be disabled
Individual audio/visual alarms can be temporarily canceled
