Dreamwear mask vibration in face tube
Just started with CPAP, Dreamstation Auto w Humidifier, Dreamwear full face mask. Problem: vibration or pulsation in the mask's air tube on side of face. More on one side but can happen on either side. Intermittent, more likely to happen when pressure is in 9-12 range (my range is 5-12). Vibration and noise wakes me up. Pressing on the face mask can stop it momentarily but then it returns when no longer pressing. Leak test claims all is o.k. Not feeling any unusual external leak. What might cause such noisy vibration, and how to fix? Partial air blockage in face tube? Bad connection somewhere? Water droplets in tube? Any thoughts or advice appreciated. Thank you.
