Hello friends at Sleep Guide Discussion Board. I just got back from an appointment with the Pulmonary/Sleep Specialist and was told the following.
My sleep study from last Tuesday evening was very interesting. Based on the result my AHI score were 106.5 per hour and this was one of the worst cases of central sleep apnea she had seen. They believe that my CSA is in direct correlation with the brain tumor removal I had in April 2007 in addition to oxygen saturation levels dropping down to 70% at times throughout the night. Their recommendation is a follow up study with the iintroduction of CPAP useage and the they want to try to find the appropriate mask. They are recommending the ResMed Liberty mask since I already know I can't use the Ultra Mirage full face mask due to seal problems in the past. They have also indicated to me that the equipment they would like to use in this situation is the Adaptive Servo Ventilation (ASV) but insurance requires proof of failure using CPAP before they will authorize ASV useeage/purchase. Is this a common practice for insurance to require use of CPAP, which is least expensive treatment, before they authorize the ASV technology? And has anyone out there on the discussion board had experience using ASV?
Thank you for all your help. I appreciate the folks here on Sleep Guide and value their input.
