Understanding Micropaq and the FlexNet Network
The monitor is intended to operate with an Acuity Central Station as part of Welch Allyn’s
FlexNet network. FlexNet allows multiple devices to communicate through hardwired
Ethernet networks and Wireless Local Area Networks (WLANs). The Acuity Central
Station provides the primary display and entry of patient data for a patient connected to
the monitor.
Each patient-worn monitor supports two-way communication with an Acuity Central
Station through an access point in the FlexNet network. The access point is a digital radio
transceiver that connects to the FlexNet network. During monitoring, the monitor sends
the patient data to Acuity. Acuity and the monitor continuously analyze the data. Acuity
provides appropriate alarm or alert messages at the Central Station and other network
devices such as a hallway message panel and the monitor itself. Acuity also stores the
patient data for viewing or report printing.
If the monitor is moved out of range or loses communication with the FlexNet network
and Acuity, it continues to monitor the patient and display patient data. While not
communicating with Acuity, the monitor continues to generate local patient alarms or
alert messages. Patient data is not stored and Acuity does not perform waveform analysis
or generate arrhythmia messages while the monitor is not communicating with Acuity.
When the monitor is returned to within range of the FlexNet network, it automatically
reconnects to Acuity.
