Regarding Oxymeter Saturation reading
Hi Doctor,
I am 31 years old female, and I am covid Positive. Today is my 3 rd day. I had mild symptoms like - mild, fever, bodyache and little bit of cough. I have this habbit of checking my Oxygen saturation on Oxymeter. I wanted to know when I check on the right hand index finger it shows 93-94, immediately I check on right hand index finger it is 99. Do both fingers give different readings. Also after exercise sometimes it increase to 99 or immediately after 10 mins it's down again to 94. Why there is fluctuations within seconds of checking.

Pulseoxymeter works on the principle of detecting the capillary pulsation , it's concentration and blood flow.
Next Steps
when it is used finger should be rubbed for few secs to improve circulation and insert the pulseoxymeter, wait for 10 to 15 secs. immediately it will just show you the small lines which will gradually start detecting the pulsation, and once you see a pulse graph, that is the correct saturation.

Difference between oxygen saturation of fingers in not valuable. Highest saturation level should be considered as normal. It can influenced by various factors like hand dominance, middle vs index finger.
