Figure 3-14 Functional Block Diagram of Patient Database Services
Patient Database Services receive real time patient data from SDN bedside and
telemetry monitors through the Physio Data Server and transmits them to the hard
disk for storage. Patient Database Services also retrieve the stored data on request
from the Physio Data Server for distribution to Information Center Applications and
other Services.
Patient Database Services interface with the OS File System through a Database
Interface, which directs data for storage to either a MS SQL Server
TM
Database or
the NT File System. Data stored are editable unit settings and patient data, such as
name, id, demographics, alarms, and configurations (about 1% of data). All other
patient data are stored in the NT File System in standard NTFS (flatfile) and sequel
database format for later retrieval by applications. Up to 96 hours of waveform data
can be stored for each patient. As noted earlier, the Registry maintains configuration
data for the application software.
Note Only configuration data from the Registry and editable unit and patient data from the
MS SQL Server
TM
Database are archived on the Archive Disk.
