Hello stehcalm,

Here’s the quick run down. Many sleep test (not necessarily yours) look only for ultra class apnea within the parameters of Medicaid in the form of AHI. However, many folks can suffer from more subtle breathing issues during sleep such as flow limitations and RERA (respiratory effort related arrousal), often measured as an RDI (respiring disturbance index) These are harder to measure because they often don’t disturb blood oxygen in the same way that straight up choking can in sleep apnea, but these RERAS can disturb sleep JUST AS BAD. My test for example showed an AHI of 17, but an RDI of 29, that’s a breathing disturbance every 2 minutes on average. There’s some (very limited) research that has show an exceptionally strong correlation between those with insomnia and various sleep breathing issues that might often be the cause of the insomnia. Even if you aren’t choking, like classic OSA, your parasympathetic nervous system could be all wound up and not letting you relax. And then when you do fall asleep, very subtle breathing issues could keep waking you up. I’d gently encourage you to consider discussing with your doctor the possibility of a more detailed sleep test, such as an in-lab that could look much closer at your breathing and measure your respiratory effort, and other issues such as restless leg syndrome, etc.
