Services
Operating System The Operating System (OS) provides a layer of isolation between
the specific hardware implementation and the application
software. The OS performs system checks and allocates resources
to ensure safe operation when the system is first started. This
includes internal self-tests on several hardware modules and
configuration checks for validity of configuration with the
operating software. During normal operation, the OS continues
to run checks on system integrity. If error conditions are detected
the OS will halt monitoring operations and inform the operator
about the error condition.
System Services The System Services provide generic common system services.
In particular:
It uses a real-time clock component to track time. It synchronizes
to network time sources and verifies the accuracy of the system
time information. It is also responsible for managing persistent
user configuration data for all Measurement Servers, Flexible
Module Servers and IntelliVue Patient Monitoring System
software modules. User configuration data is stored in a non-
volatile read/write storage device
Applications
Reports The Reports Service retrieves current and stored physiological
data and status data to format reports for printing paper
documentation. The following reports are supported:
• Vital Signs Report
• Graphical Trend Report
• Event Review Report
• Event Episode Report
• ECG Report (12 Lead/Multi-Lead)
• Cardiac Output Report
• Calculations Report (Hemodynamic/Oxygenation/
Ventilation)
• Calculations Review Report
• Wedge Report
• Test Rep ort
• Other reports (e.g. Loops, Review Applications, Drug
report)
The Reports service generates report data which can be printed
on a local or a central printer.
