Basic EnsoViewer Navigation for PPG studies

Most PPG studies will be scored with 4 sleep stages (Wake, REM, Light, Deep) and will classify Obstructive and Central respiratory events.

Study Navigation:

  • Scroll by epoch by using the arrow keys on your keyboard.
    Scroll by page by using the page up/page down keys on your keyboard.
    You can also use your mouse scroll-wheel.
  • To score events, click and drag on the channel you would like to score on.
    To change an event, right click on the event and there will be a pop up with options.
    To delete an event you can either right click and delete or hover your mouse over the event and click the Delete on your keyboard. 
  • The score-able respiratory events forPPG based studies are Obstructive Respiratory, Central Respiratory, and Respiratory Event
  • Notice the icons in the upper right corner of the Channels View 
    • The Play button will auto-scroll the study. Control the speed of the auto scroll by using the Fast/Slow arrow buttons next to it. 
    • The Settings gear icon allows you to customize and save your montage, hide and filter channels, and re-order your staging hypnogram.
    • The (i) Keyboard Shortcuts info button will show you all the keyboard shortcuts for navigation. Important ones to keep in mind are 'r' for Rescale and 'b' for Bad Data.
