After my FM radio talk on sleep apnea, something unexpected happened.
People who would never have sought help otherwise started showing up.
One patient told me:
โDoc, Iโve tried everything. Still waking up like I never slept.โ
His Apple Watch? 8 hours logged.His Whoop recovery? Green most days.
His home sleep study ? Normal
But he felt awful.
I recommended a level 1 sleep study.
The results told a different story:
โ AHI: 4 (normal)
โ Oxygen saturation: 96% all night
โ RERAs: 47 per hour
Translation? His brain was jolting awake nearly once every minute trying to overcome airflow resistance.
No wonder he was exhausted.

Hereโs the distinction most people miss:
Sleep apnea = airway collapse = oxygen desturations.
UARS = airway resistance (oxygen stays stable, but micro-arousals wreck sleep)
The key metric?
RDI (๐๐๐ฌ๐ฉ๐ข๐ซ๐๐ญ๐จ๐ซ๐ฒ ๐๐ข๐ฌ๐ญ๐ฎ๐ซ๐๐๐ง๐๐ ๐๐ง๐๐๐ฑ)
Normal RDI:
