Philips Avalon FM40 Features
The Avalon FM series fetal and maternal monitors are the first and only to offer automated coincidence detection (cross-channel verification) using Smart Pulse. This innovative feature allows automated maternal pulse detection via the Toco MP transducer without the need to monitor maternal SpO2 or ECG separately. Built-in NST Trace Interpretation, clinical decision support (CDS) application for antepartum monitoring can help to improve efficiency by sorting out the traces that require closer analysis
by the obstetrician. 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.
Cross-channel verification continuously compares all fetal and maternal heart rates to ensure
that each is measured separately, enhancing confidence.
- Automated coincidence detection with Smart Pulse
- Optional external touch display, allowing flexible, ergonomic installations
- Only the Avalon FM series can monitor triplets on a single monitor using the same Ultrasound frequency
