Behavioral: Weekly phone calls
Calling weekly to answer questions regarding CPAP usage.
Active Comparator: Frequently asked questions
Providing written general answers to commonly asked questions.
Behavioral: Frequently asked questions

Answers will be provided by the renter of the equipment, and the sleep center if asked in addition to explanations by the sleep specialist.

Detailed Description:

To determine whether there is a need for a more intensive one on one interaction with the patient in order to improve CPAP usage. And also to try to identify in general which population of patients may require a more intensive intervention.
