Oximetry, more than we'll ever want to know
The recommended site (URL below) is new to me. Unfortunately, it must have been written before Covid-19 because it omits the specific contribution oximeters make to detection and care of that infection. (It is my intention to post links to information about the new use of the old drug Ivermectin in ApneaBoard's special forum on dealing with Covid when at home (when other care is unavailable and you must go it alone).
The lengthy linked article appears to be very comprehensive for deeply interested laymen, starting from basics of pulse oximetry then going deeper and deeper into it.
There's much there we can understand and benefit from. I suggest it would be good to scan it all, but do read more closely the limitations of highly useful pulse oximetry, including limitations of many medical professionals' understanding of it. Those limitations are set forth near the end of the piece. Various pulse sensors and oximeter brands are touched on.
My particular take away is that my nightly SpO2 average of 92.5-94.5% is a bit low, but 90% is marginally OK. Possibly my low resting SpO2 was inherited from my mother who had some (unknown to me) level of anemia , which I have long (or always?) had with my four present slightly low blood cell counts. I have low Iron despite eating lots of high Iron foods and taking Iron supplements along with vitamin C to enhance absorption.

I have no particular qualifications or expertise with respect to the apnea/cpap/sleep related content of my posts beyond my own user experiences and what I've learned from others on this site. Each of us bears the burden of evaluating the validity and applicability of what we read here before acting on it.
Of my 3 once-needed, helpful, and adjunctive devices I have listed, only the accelerometer remains operative (but now idle). My second CMS50I died, too, of old age and the so-so Dreem 2 needs head-positioning band repair--if, indeed, Dreem even supports use of it now.
