Epworth Sleepiness Scale - online assessment of clinical changes
You are invited to participate in our survey. Our goal is to find out if you feel you are benefiting from your CPAP/BIPAP therapy.
In the following question set we will ask you how likely are you to doze off or fall asleep in different situations.
This refers to your usual way of life in recent times. Even if you haven’t done some of these things recently, try to work out how they would have affected you. Use the following scale to choose the most appropriate number for each situation:

0 = Would never doze
1 = Slight chance of dozing
2 = Moderate chance of dozing
3 = High chance of dozing
