The cushion is available in four sizes. Select size of cushion at the time of ordering.
Sizing Assistance: The manufacturer offers the following information to assist in selecting the correct size cushion for the Wisp. Measure from the outside of the nose from one side to the other. Do not measure only the nares or nasal openings, but the entire width of the nose.
To find the size of the nasal cushion, look at the bottom of the silicone cushion, where the mask frame and nasal cushion connect. A large, black letter will indicate the size of the nasal cushion.
System One Resistance Control Tips
If using a Respironics System One machine, a system one resistance control number from Respironics can be set to allow the machine to compensate for different mask types. The resistance control number for the Wisp Nasal CPAP Mask is X1. Please Note: System One Resistance Control is for System One Machines only.
