Data Flow
The following diagram shows how data is passed through the monitoring system. The individual stages
of data flow are explained below.
Data Acquisition
Monitoring data (for example patient measurement data in the form of waves, numerics and alerts) is
acquired from a variety of sources:
• Measurement Servers
The Measurement Servers connected to the internal LAN convert patient signals to digital data and
apply measurement algorithms to analyze the signals.
• External measurement devices
Data can be also acquired from devices connected to interface boards of the monitor. Software
modules dedicated to such specific devices convert the data received from an external device to the
format used internally. This applies to parameter modules and the Anesthetic Gas Module
• Server systems on the Philips Clinical Network
To enable networked applications such as the other bed overview, data can be acquired from server
systems attached to the Philips Clinical Network, for example a Philips Information Center
Data Provider System Service
All data that is acquired from measurement servers or external measurement devices is temporarily
stored by a dedicated data provider system service. All monitor applications use this central service to
access the data in a consistent and synchronized way rather than talking to the interfaces directly.
This service makes the applications independent of the actual type of data acquisition device.
