Kathy, on behalf of the SleepGuide Crew I would like to welcome you to the forum We are here to fill in the gaps in education and help left by our DMEs and doctors. We try to teach you about your "numbers" and what they mean to enable you to be active in your treatment. Things like getting the mask to fit and not leak, dating with CPAP, travel, new therapies, the different modes of treatment- anything about sleep and sleep apnea is up for discussion. Glad to have you.
