[CPAP] Are these RERAs?

[uarsquestions]

Hi everyone, this is my first post here, thank you so much in advance for your help! 

I would like input as to whether these flow rate/limit spikes are indeed RERAs.  

Notes:

• Pressure setting = 4 CPAP
  
• Did this for baseline diagnostic 
  
• First hour of sleep only, so not even deep sleep 
  
• In-lab sleep study diagnosed me with moderate UARS (RDI = 17)
  
• Was on APAP (4-20), minimal benefits 
  
• APAP lowered my AHI but RDI was unchanged (by my eye, at least...)
  
• Not using PAP nightly any more (waiting on custom OAT)
  

Some Additional Background 

• Had a DISE; issues = recessed jaw, collapse of soft palate, tongue, epiglottis 
  
• Soft palate and tongue issues resolved with jaw thrust (epiglottis not resolved by anything) 
  
• Did follow up sleep study to confirm before surgical next steps (different lab than first study)
  
• ....study #2 says AHI = 2.6.....and RDI = 2.6 (so no RERAs); and yet AW+AR/hour went UP (lab #2 says they are all "spontaneous")
  
• I do not trust sleep lab #2 given my DISE, below PAP data, and results of sleep study #1
  
• So I want to make sure I am interpreting the below correctly; then maybe get a third study from a third lab??
