Pressure 6,1 - 8,4 - 9,6
6.1 is median pressure, pressure was at or below this number for 50% of the time
8.4 is 95% percentile pressure, pressure was at or below this number for 95% of the time
also its the one displayed on the machine LCD sleep report
9.6 is the maximum pressure, pressure at or blew this number and above 95% percentile pressure for 5% of the time
Leak 1,2 - 6,0 - 12,0.
Same explanation as "Pressure", just substitute the word pressure with leak
S9 report unintentional leak (mask plus mouth leaks) = [total leak less intentional leak (mask vents leak rate)]
You,re asking what would be normal?
Leak at or below 24 L/m is an acceptable leak .. the red line shown on detailed data leak graph. Higher leak rate affect the accuracy of the data and causes sleep disturbance. Leak numbers are excellent indicate very good mask fit/seal
There is no such thing as normal, different people need different pressure to maintain open airways, your pressure is only relevant to you on this particular night. Pressure might vary slightly from one night to the next.
Keep up the good work
