Refurbished - Corometrics 118 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 cancelled
