Nasal True Blue

The ComfortGel Blue Nasal CPAP Mask with Headgear uses technology developed by Respironics. Improvements can be found over the earlier versions in the gel cushion and forehead pad design. A new angled elbow and exhalation micro ports reduce overall sound. Lastly, the cushion is now labeled with a System One Resistance Control rating. PR System One machines use this rating to identify and adjust pressures based on the mask used.
