1. "Patient HAS been diagnosed with OSA"
This is incorrect and MUST be corrected: The Primary diagnosis needs to be Central Sleep Apnea Primary central sleep apnea G47.37 or Primary central sleep apnea G47.31. The secondary diagnosis can be Obstructive Sleep Apnea G47.33, and lucky you get a third whammy Periodic Limb Movement Disorder
Your hypopneas were not evaluated to determine if they are also central so they are assumed to be obstructive. In reality, most are likely to be central in nature. Thus an argument could be made to drop the Obstructive Apnea diagnosis.
Recommendation #1 WILL NOT WORK for you. Why? there is no timed backup and way too little pressure support
Recommendation #2 ASV or Adaptive Servo Ventilation WILL work for you. The lab recommended returning to the lab for titration to prove the efficacy of an ASV. As others have noted above you have a couple of choices to make in how you choose to get this machine but rest assured this is the ONLY machine that will work for you. I too recommend the Resmed over all others.
