What is happening in the apneas below? (Note: undiagnosed)

[justsome1confused]

Hey all, hope you are doing well. I've been having unrefreshing sleep alongside other classic sleep apnea symptoms(brain fog, waking up with a dry mouth and headache, occasional low O2 sat at nights 80-85% according to wearables) for years. I've looked into a sleep study but the closest one I can get without paying out of pocket is easily months or a year away where I live+at home studies have horrible availability. So I resorted to sketchy DIY studies to evaluate if I have any obvious apnea or not.

I slept with a microphone taped in my nostrils for a rough recording of airflow for a few days and it seems I have around 60-80 apneas a night, with my worst hour having around 20. Some hours I don't have them at all. The pattern is the same: I deeply inhale, exhale, then stop breathing(or breathe really shallow) for anywhere between 15-40 seconds. I assume none obstructive because I don't struggle to breathe, don't wake up gasping for air and don't snore.

Since all I have is an audio recording I don't have a reliable flow rate graph, but I'll post the waveforms in Audacity from the recording if any of you have ideas(each spike in the waveform indicates exhalation since the mic picks that up best).

Note: I'm not asking for a diagnosis, just wondering if any of you have this many of this type of apnea and if I should be particularly concerned about them. I'm aware only a sleep study can tell for certain what is going on. Also keep in mind I'm not on any sort of PAP or ventilation device

Thank you!
