I'm curious about something that's been happening to me. When I use my oximeter, my SpO2 starts at 99 for about 10-15 seconds, but then it drops to 90 or even 88. I don't have any symptoms like breathing issues, my heart rate is around 68, and I'm not taking any medication right now. What could be causing my SpO2 to drop like that?
