Avalon CL, part of our obstetrical and fetal monitoring and information management portfolio, works easily with our Avalon fetal monitors. The cableless transducers transmit fetal and maternal vital signs information to a fetal monitor via the base station. From there, patient information can be transferred to our IntelliSpace Perinatal information management system.

Three types of transducers

Three types of cableless transducers are available. An ultrasound transducer measures fetal heart rate and fetal movement. The Toco+MP transducer measures uterine activity, maternal pulse, and either maternal ECG, fetal ECG, or IUP. And the ECG/IUP transducer measures either maternal ECG, fetal ECG, or intrauterine pressure (IUP).
