+ | The study opens automatically as “default-scoring -1” – you need to choose **aSAGAalgorithm_uncertain**. | ||

+ | |||
+ | **1.** Start by running automatic analysis (it is needed for the respiratory and arousal scoring): Analysis -> “Nox SAS and Respiratory Analysis” (fig. 4). It will not overwrite the previous sleep staging. | ||
+ | |||
+ | < | ||
+ | |||
+ | **2.** Adjust the timeframe (start and stop times for the correct analysis period) on the Recording results tab by dragging the analysis start and stop bar on each side of the study overview, this can be adjusted further when you are in the scoring tabs. | ||
+ | |||
+ | **3.** Score sleep epochs marked as “_uncertain”. Other parts should not need editing but ok to do a quick review. (tab: SR SAS EEG), see fig 5. | ||
+ | |||
+ | < | ||
+ | |||
+ | **4.** Score respiratory events using the recommended rules by the latest AASM version (currently v.3.0). (tab: SR Respiratory) | ||
+ | |||
+ | **5.** Score LM events (tab: SR PLM) | ||
+ | |||
+ | **6.** Use Tools -> Update PLM (PLM events are made from the LM events where appropriate) (fig 6). LM events that are counted in the PLM series are changed to PLMS events, whereas those that are not a part of the series are still labelled as LM events (they don´t fit the criteria and are therefore not counted in the series, like an event that occurs during a respiratory event). See fig.7 and text below for clarification. Unmark the “starting in a movement event” when running the Update PLM tool (fig. 8) since it often causes many actual LM events to be left out. | ||

+ | **7.** Use Tools - > Arousal Tool (fig. 9) (arousals are classified: respiratory arousals, LM arousals, PLM arousals). Before running the tool change the <5 by clicking on the number and write 10 instead (fig.10). | ||

+ | |||
+ | **8.** Review the arousals in the arousal classification tab to review if the arousals are correctly classified and correct if needed (SR Arousals). | ||
+ | |||
+ | **9.** To save the scoring choose: “Save scoring as”: use your initials (fig. 11) and be careful to save it in the end so there is not “(modified)” behind your initials. | ||
+ | |||
+ | < | ||
+ | |||
+ | **10.** In the “Recording Results” tab change the status of the scored recording from “New” to “Scored” (fig. 12). This will help you keep an overview of your scored studies in the recording library. | ||
