optimize the processing speed of the system. At a minimum, the Workstation should be
shutdown weekly.
When the Shutdown Computer dialog box displays "It is now safe to restart your computer",
turn off the computer. Allow it to remain off for a minute and then turn it back on.
Depending on how much optimization needs to occur and how long it has been since the
system was last shutdown, it may take as much as 60 minutes or as little as five.
One factor in the system configuration that can affect communication and overall operation
of the Workstation is the amount of data that is being stored within the system. The amount
and type of sample results that are stored in the Workstation is defined in System
Setup-[Database Preferences].
The three types of data and the size for these choices are:
Sample Numeric Data: All patient demographics and numeric parameter results
r
Range: 1000 to 20,000
t
Graphics: WBC, RBC and PLT histograms
r
Range: 500 to 5000
t
Listmode Data: Raw VCS data used in the development of histograms and VCS dataplots
r
Range: 50 to 500
t
The number of records in the database affects how long operations that search within the
database will take. The number of sample records, therefore, impacts how long certain
functions take to be performed. Examples of these functions are,
searching for collation matches,
r
looking for previous samples for Delta Check rules
r
It is the number of records, not the space they take up, that affects how long it takes to
perform these functions.
When setting these preferences, consider why your laboratory will go back to review the
stored information and how many samples are typically run during a 24 hour period.
Questions for you to consider:
Does the laboratory use Delta checks? If so, what is the time frame for check?
r
Does the laboratory use the Histogram for parameter review?
r
Does the laboratory print abnormals or is the Workstation utilized for the review?
r
Does the laboratory lock patient results and store them in the database?
r
If you do not have a Laboratory Information System to store data, you may want to consider
archiving data to disk rather than long term storage in the Workstation.
