Wristband with Sp02 alarm <90% for preventing apneas?

I tried searching for this but returned 1000+ irrelevant results (search skills)

Seems like a very basic and obvious question: Does ANYONE know a watch / wristband that measures Surface Oxygenation / Saturation (Sp02) that can vibrate or alarm before dropping to low to prevent you getting an apnea, by waking you up?

It seems like the most vital bit of kit for anyone who suffers apneas.

Anyone? Thanks.

yes, I do, it's a stupid idea. better to get a cpap and not have to worry about it anymore... plus, you get sleep, instead of being waked up even more, repeatedly.

as to search skills "wrist oximeter" would probably get you what you think you want.

To qualify as having sleep apnea, you need to average 5 or more events per hour. Do you really want to wake up 5 or more times per hour? Mine was 79 an hour. With that alarm, I migh as well stay awake all night.

I would rather prevent the events and sleep. A lot more restful.

What part of preventing wake ups did you miss? Would you like someone to shake you awake 5, 10 70 times an hour? Do you think you will get restful sleep that way?

An SpO2 meter like the CMS50F wrist meter can be set to alarm mode if the value drops below some particular level. Typical values to consider are number below 90%.

Unfortunately, it will be reporting, after the fact, the apnea event that led to the low level - a little too late to do something to prevent the event.

That having been said, it is a useful device to help in determining how severe your apnea events are dropping you O2 levels at night. Reviewing the data the next day will be adequate for that function.

The references to apnea events at elevated rates with regard to SpO2 drops are a little misleading. Most apnea event do not drop your SpO2 enough to be a bother. Its the event itself that is the problem. I use a pulse-oximeter every night and look at the data every day. I seldom, if ever, saw O2 drops below the 90% level and then just a couple of times per night. If that is your case, then the alarm function would waken you once or twice at night and might have some utility. OTOH, extra awakes come with their own costs in fragmented sleep. I chose to not use an O2 alarm. You might make a different choice.

Sleep deprivation is recognized internationally as a form of TORTURE.
