PRANA - Polygraphic Recording Analyzer

Session information

The PRANA® software for biosignal processing offers a permanent access to every session-related information, with an instant and synchronous display of the recorded signals, the expert scored stages and all the software analysis results.

Session information tools

• The session recording dialog-box displays the name, location and information of the recording file(s) used in the current session, as well as the montage and calibration settings used.
• The session analysis dialog-box displays for the current session the name, location and information of the different analysis and detection files obtained from using the different software suite plug-ins.
• The session audit dialog-box displays the different actions performed by the current registered user and keeps track of the executed software plug-ins with all their related settings.

The software, in partial compliance with the standard requirements for computer uses and electronic records in the context of good clinical and laboratory practise (ICH - 21 CRF Part 11), ensures audit trail recording of all software operations and plug-in settings and non-repudiation of results with date, time and user stamping and centralized authorisation.

Stage scoring report

The PRANA® software for biosignal processing has convenient reporting capabilities.

Stage scoring report generator

The software report generator can configure and perform the instant edition and printing of comprehensive study reporting as computer files containing the relevant data and graphical representations.

The software continuous scoring report computes and displays the statistics related to the sleep-wake stages and contains:

• the patient and study information, the hypnogram and general sleep parameters,
• the internal sleep structure with stage characteristics, sleep-wake stages duration, latency, stability and cycle characteristics,
• a set of graphics summarizing sleep-wake stages proportion, cumulated stage duration, etc.

Sleep/wake stage scoring report

The software iterative scoring report for iterative vigilance tests (MSLT, MWT, others) computes and shows the temporal distribution of the sleep-wake stages (latency and proportion) as a graphic summary with the corresponding data available as text file.

Event marking-annotation report

The PRANA® software for biosignal processing has convenient reporting capabilities.

Event marking-annotation report

The software report generator can configure and perform the instant edition and printing of comprehensive study reporting as computer files containing the relevant data and graphical representations.

The software marking report computes and shows the distribution of any event type by sleep stages and sleep cycles and contains:

• the patient and study information,
• the global event type statistics (number and mean duration),
• the internal sleep repartition and the corresponding statistics.

Signal analysis report

The PRANA® software for biosignal processing has convenient reporting capabilities.

Analysis report generator

The software report generator can configure and perform the instant edition and printing of comprehensive study reporting as computer files containing the relevant data and graphical representations.

The software analyses report computes and displays the distribution by sleep stages and sleep cycles of any time series obtained after execution of a software optional plug-in. The report contains:

• the time course of selected parameters and the concurrent hypnogram,
• the mean value of selected parameters by sleep stage in sleep cycles and by sleep phase in sleep cycles,
• the slope and intercept values of selected parameters by sleep phase in sleep cycles,
• the cumulative value of selected parameters by sleep phase.
