After a WP100 sleep study, remove the Compact Flash card from the WP100 and insert it into the zzzPAT Compact Flash reader. The recorded digital data along with patient information are loaded into the zzzPAT database. The recorded data is automatically analyzed. The user can subsequently review, edit, add Diagnosis and Recommendations and produce a Sleep Report. Previously loaded studies can be opened and reviewed.
