Calc Param The Calc Param (Calculated Parameters) service accesses current,
stored and manually entered physiological data as input to
calculation formulas. With these formulas, derived
hemodynamic, oxygenation and ventilation variables are
computed. The calculation results, including the input
parameters, are stored for later review using the Trend service.
Interface Managers
MDSE The MDSE (Medical Data Service Element) Interface Manager is
responsible for the exchange of real-time data between the
IntelliVue Patient Monitoring System display unit and the
Measurement Servers and Flexible Module Server as well as
between the IntelliVue Patient Monitoring System display unit
and other devices attached to the network. MDSE establishes and
maintains a data communication link between the devices. It
provides configuration information about the remote device to
applications in the local device and it allows the exchange of
measurement data and status information between the devices.
Printer The Printer Interface Manager provides a high level interface to a
printer. It provides means to:
• establish a connection to the printer
• transfer data to the printer
• get status of the printer
• close connection to the printer
The Printer Interface Manager also supervises the connection to
the printer and whether the printer accepts data (for example
paper out). The Printer Interface Manager notifies the operator
in such cases.
