4.1 Preparing a New Study
Preparing the Patient file is a mandatory stage in the preparation of the WP100 or WP200 devices for a sleep study. Before proceeding, make sure that the Compact Flash reader drive was defined as described in Section 2.7.

Local database should be selected only if network access is not available, or for special purposes (training, travel etc…).
Note
In Shared Access mode, if data was stored on the local database, it is recommended to export the data into the Shared Access database as soon as practical. y
If applicable, select the desired database to connect to. Local database should be selected only if network access is not available, or for special purposes

4.1.3 New Study screen features
Besides the main screen fields required for preparing a new study, there are additional fields that allow thorough documentation of the patient's past and current medical condition. In addition, zzzPAT enables you to load patient details from previous studies.
Other features in this screen enable organizing the studies into groups using categories of your choice.
4.1.3.1 Synchronizing the WP100 device clock with the zzzPAT software
The internal clock of the WP100 device needs to be set correctly in order for the Study
Date/Time to appear correctly after loading a study in zzzPAT.
Since zzzPAT version 3.0 all WP100 devices are delivered from Itamar Medical having the internal clock set to GMT (Greenwich Mean Time).
The “Time Zone” field in “New Study” screen contains the offset in hours that is added or subtracted to the Study Date/Time read from the WP100 device.
• If the WP100 device clock is set to GMT - this offset equals to the difference in hours between the computer’s local time and GMT
• If the WP100 device clock is set to local time - this offset equals to zero (select GMT on the pull down menu)
To adjust for daylight savings or if you notice a discrepancy in hours between the actual
Study Date/Time and the one obtained in zzzPAT, you can change the “Time Zone” field in
“New Study” screen in order to compensate for the discrepancy:
• If zzzPAT date/time is later than the actual Study Date/Time - decrease the “Time
Zone” zzzPAT 4.2
Itamar Medical Ltd.
• If zzzPAT date/time is earlier than the actual Study Date/Time - increase the “Time
Zone”
Note
You do not need to set the “Time Zone” field each time you prepare a New Study. The software “remembers” the last “Time
Zone” used.
Note
The local GMT offset can be found in Start>Settings>Control
Panel>Date and Time>Time Zone.
Note
When you run Watch-PAT Monitor (version 2.1.45.1 and earlier) with WP100 devices whose clock is set to GMT the Date/Time test will fail.
As long as the difference between the WP100 device clock and the computer clock is equal to the GMT offset, the device clock should be left unchanged.
4.1.3.2 Synchronizing the WP200 device clock with the zzzPAT software
Select the "Synchronize WP200 clock with PC clock while 'Saving to USB'" option while preparing new study if the WP200 device clock needs too be set (see Figure 39).
