I finally got a sleep study which showed No Evidence of Sleep Apnea with an AHI less than 3.
However, it showed Nocturnal Hypoxemia with SpO2 down to 80% for a total of 90-120 minutes throughout the night.
I am 35 yo, 5’10, weigh 185. BMI is less than 25.
The only other thing I know I have is a severely deviated septum and nasal valve collapse.
However, I’ve been told by people that deviated septum and nasal valve collapse alone shouldn’t cause me to have low SpO2 levels at night.
Follow up Pulmonary Function Test (PFT) and Echocardiogram was normal.
Purchased myself a Medical Grade SpO2 monitor for sleep – average SpO2 levels throughout most nights were 89%-92%. Purchased a CPAP (AutoPAP) and it made absolutely no difference in my average SpO2 levels at night.
Any input would be appreciated. I am getting a septoplasty, nasal valve repair, and turbinate reduction done regardless.
