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 no...
The fluctuation in your SpO2 readings, dropping from 99% to 90-88% without symptoms, could be due to various factors, including poor circulation, cold hands, movement, or sensor accuracy issues; however, given your normal heart rate and lack of symptoms, it's essential to consult a pulmonologist to rule out any underlying conditions, such as sleep apnea, pulmonary embolism, or cardiac issues, and to determine if further evaluation or testing is necessary.
