How accurate is the pulse sleep oximeter? my stats are coming in around the mid 80's!!
As Fer mentioned, pulse ox readings have to be taken with a grain of salt. But as Garmin refines the firmware for these new devices, perhaps numbers will become more accurate.
My night recordings average low 90's, but I sometimes see short-term drops to low 80's. Am in mid 40s, VO2Max 52, BMI of 21. Daytime saturation levels are 95-100% with a recorded low of 91% which should not be the case for a guy like me at sea level (same as what DCR noted in his review, his values were low too). Garmin's documentation states:
"If your pulse ox during sleep reading seems low, it may not necessarily indicate low pulse ox saturation. Your arm position can influence blood flow to your wrist and can adversely affect readings, typically making them lower than they really are. Where possible maintain a position that is conducive to good circulation and at or around heart level."
What could Garmin's product team do to help us make sense of the numbers?
What about the ability to set a beeping/vibrating alarm if SpO2 drops under a certain value? It would wake the user in the middle of the night, but after a few times, we would be able to somewhat identify if at the time of alarm, we were sleeping on the arm that's wearing the watch. It seems like an easy feature to add to current models until they refresh the product line 3 years from now.
