I have done a home study results few times ago regarding a daytime sleepiness and fatigue, waking up with a dry mouth/throat and a general sensation of 'never feeling rested" ever since i was 17. Also checked blood panel (including hormones, vitamin any kind of deficiency) and nasal obstruction at ents (scan and allergy), here are the results:
- 5h recorded
Apneas : 5
AHI : 1
Average length : 13 sec
Longest length : 19 sec
OSA Number : 4
CSA Number : 1
Hypopnea 1 total, micro awakening 2 per hour
Snoring 53, 15 per hour
Events 3
Total events length 2 minute
Strength 81 dB
Sp02 awakening : 99%
Sp02 average : 97%
Sp02 lowest : 95%
The results are quite negative as you can see, but the weird thing was that i slept even worse than usual and woke up slightly more, yet i still have such a low ahi? I don't know about nasal obstruction thought because they didn't put a oronasal sensor, only o2 oxi and chest one
Would it be worth doing a full lab study to check what is disturbing my sleep? I feel like i'm going mad, randomly sleeping, 4h to 8h, always same symptoms (it feels like i'm always deprived of sleep, nothing else tbh)
Only thing i noticed was that once laid down, my nose start getting really "dry" no matter the humidity/temp, and not only at night but anytime. but if i'm awake up i don't have any blockage or runny nose, never mouthbreathed in the day in my life

Thanks for reading
