Is the AW 6's SpO2 sensor used at all to measure sleep tracking? I've been switching between an aluminum S4 and a stainless S6 but I'm not sure I'm seeing any difference in how sleep is measured.

If not, I'd likely opt for the S4 for sleep tracking since it's a bit lighter and less useful during the day without AOD. If there's some benefit to having SpO2 measured during sleep, then I'd drop back to the S4 during the day whenever the S6 needs charging.
 
Sp02 tracking when sleeping is the MAIN reason to track it. At sleep, Some alveoli shut down, and a healthy reading is 89 or above . if you’re less than that, one of the confirming factors is you wake up with a headache, mostly focused in the rear of head. I’m about to go on an oxygen concentrator just at night, as my sleep SPO2 is 86 to 88, that’s too low,.
 
Mine is OK.
I don’t think this will change dramatically day to day. Once you measure it for a week or so you should have a good idea of where you are.
then you can go back to aw4 for sleep monitoring.

Thanks for the feedback.
 
SPO2 results won’t be found in the stock Sleep app. However, the separate SPO2 results can be used in conjunction with one’s sleep app results to give a better overall view of lung function during sleep and possibly help a doctor better diagnose one with possible sleep apnea or the early onset of COPD etc.

I think it is fairly accurate.

I use a CPAP, so my AHI** (apnea/hypopnea index) when using it is low. Like golf, lower is better. That means my airway is not restricted.

So w/CPAP usage my spO2 (according to AW6) is 95%-97%

This morning I woke up around 530 and went to the living room to watch early morning news and fell asleep w/o CPAP and for that hour it measured 92%

Which I think makes sense. Over the years I've lost weight and stopped snoring w/o CPAP so I don't think my AHI is super high w/o CPAP, but enough that there is some restriction...certainly not enough to drop my spO2 to moderate or severe sleep apnea levels like it was 10 years ago (Where my AHI was 80-90


** events per hour that last 10 seconds or longer; full pauses (apnea) or shallow breathing(hypopnea)
