The HP/Philips Fetal Monitor Series 50XM is a high-quality unit utilized during delivery and labor. It provides continuous maternal vital signs monitoring and maternal non-invasive blood pressure readings. It features individual twin’s heart rate monitoring as well as uterine activity calculated in relation to a selected baseline. The 50XM
provides signal quality indicators for each fetal heart channel for optimal transducer placement. The color-coded sockets match the transducer cables for easy identification.
