Philips Avalon CTS Rear Interface

Philips Avalon CTS M1351a Features
The Avalon Cordless Transducer System (CTS) helps transform labor and delivery, offering mothers and
care teams the flexibility they seek by allowing comfortable, continuous fetal and maternal monitoring with
exceptional mobility. Avalon CTS helps provide a constant and clear picture of patient status for confident
decision-making.

Cordless toco transducer: externally measures uterine activity
Cordless ultrasound transducer: measures fetal movement and heart rate
Bed identifier: matches transducers and base stations for each bed
Base station receives transducer signals: and recharges plugged-in transducers
Transducer plug and play with automatic screen layout, in combination with Philips fetal monitors, allows focus on patient care, not the system
Transducer status indicators: shows how clearly system is working at all times
Slot position indicator: helps ensure each transducer is returned to its proper home position
Cordless ECG transducer: measures direct fetal ECG or maternal ECG
Battery charge indicator: shows status of charge (Batteries operate at least 16 hours
