Scroll down the graphs, one will have red lines w/a box at top w/a number in it. The red lines are the apneas you experienced that night. The number in the box is the length of time in seconds that apnea lasted. Your Resmed adds up the number of apneas and divides them by the number of hours you slept to determine your AI (apnea index=number of apneas per hour you experienced).

Its been quite a while since I used the Resmed S8 Elite w/EPR, the Elite model previous to your S8 Elite II. So I don't remember all the graphs provided by the Elite data. I use the Resmed VPAP Auto now (a bi-level).
