With Avalon CTS, expectant mothers are untethered from the fetal monitors. Wearing the lightweight, cordless transducers, mothers-to-be can move about with more freedom and comfort, and even bathe while being continuously monitored. The system measures external fetal heart rate and movement, uterine activity and maternal ECG. It uses radio frequency (RF) technology to transmit information to a base station, Philips fetal monitors, and the OB TraceVue information management system. Information from Avalon can become part of a comprehensive overall patient record. ㆍWireless surveillance gives mothers and care teams more freedom Avalon CTS features Base station that also recharges transducers Cordless, waterproof ultrasound, Toco, and ECG transducers Transducers are lightweight (only 120 grams or 4.23 oz.)

From there, data can be charted and stored automatically, using Philips’ OB TraceVue obstetrical data management system.
