Philips Avalon FM50 Fetal Monitor

Description

Philips Avalon FM50 Fetal Monitor Features

The Philips Avalon FM50 Fetal Monitor offers a solution for both external and internal fetal monitoring applications, and optional non-invasive maternal vital signs. The Avalon FM50 can monitor fetal heart rates (FHRs) externally using ultrasound, uterine activity using a toco transducer. The Maternal heart rate (MHR) is measured using ECG electrodes. This Philips fetal monitor can also measure Non-Invasive Blood Pressure (NIBP) and maternal oxygen saturation (SpO₂). Additionally, the FM50 fetal monitor can monitor one FHR internally via direct fetal electrocardiogram (DECG), and uterine activity internally using an intrauterine pressure (IUP) catheter. This fetal monitor is capable of intrapartum monitoring.

The measurements are displayed on a 6.5-inch color display as numerics. You can operate the FM50 using the touchscreen interface. Measurements are recorded and can be printed out via the onboard recorder.

This fetal monitor is compatible with the Avalon CTS Cordless Fetal Transducer System. Only one CTS Cordless Fetal Transducer system can be connected at a time. The user has the option to either use wired or cordless fetal transducers. Using both wired and wireless together is not supported in this unit. Cordless transducers have priority over wired transducers. When an Avalon CTS base station is connected via the appropriate interface cable, and there are wired transducers connected, the wired transducers are disabled.

Extensive Fetal Parameters When Key Information is Needed

For more complex cases, the Avalon FM40 fetal monitor offers external and internal fetal parameters. These include ultrasound, fetal movement, direct fetal heart rate, Toco and intrauterine pressure, as well as maternal blood pressure, pulse rate, ECG, and Sp0₂.

IntelliSpace Perinatal Connectivity for Continuous Care

The Avalon FM40 fetal monitor connects to IntelliSpace Perinatal, Philips obstetrical surveillance and information management system. This supports the continuum of care from the first antepartum visit to delivery, postpartum, newborn nursery, discharge, and postpartum follow-up visits.

Triplet Monitoring Option Expands Capabilities

Only the Avalon FM series can monitor triplets on a single monitor using the same ultrasound frequency. This allows one monitor to be used for a wide range of clinical needs.

Smart Transducers to Simplify Operation

The smart transducers have auto-recognition and “Finder LED” that automatically see which transducer is plugged in. When the transducer is plugged in, the screen layout automatically displays data in the correct format. This simplifies operation for caregivers.

Smart Pulse for Automated Coincidence Detection

Smart Pulse provides cross-channel verification and allows automated maternal pulse detection via the Toco MP transducer without the need to monitor maternal SpO₂ or ECG separately.

Avalon CTS for Freedom of Movement

When connected to the Avalon Cordless Transducer System (CTS), mothers can freely move up to 100 meters from the CTS base station during continuous monitoring by the care team. The CTS also transmits data to the IntelliSpace Perinatal information system to add to the overall patient record.

Large, Intuitive Color Display Clearly Shows Status

The luminous color display has large numerics and graphs so you can easily view maternal and fetal ECG waves.

Reliability Features Provide Additional Support

With the Avalon FM series, you have the confidence of continuous data with a backup memory, battery operation, and LAN interface, combined with smart transducers and a color touchscreen.

Variety of Readings for Comprehensive Understanding

This antepartum and intrapartum monitor provides a wide range of readings. These include separate maternal pulse measurement; integrated monitoring of maternal pulse rate and blood pressure; external monitoring of fetal heart rates, uterine activity, and fetal movement; and an extensive set of internal fetal parameters such as direct fetal heart rate and uterine pressure. Maternal SpO₂ monitoring is included as standard.

External Touch Display Option for Flexibility

The optional external touch display gives caregivers flexibility in placing the monitor where it can be easily viewed by family members and caregivers.
