My mother is showing different spo2 reading on different fingers her reading can vary from anywhere between 78-98, i tried to check her reading within 10 mins on all 10 of her fingers for most of them there was no reading And for others it was varying alot. I am concern about it she do have bp issues and to get confirmation about whether she have covid or not I got her city scan done which confirmed my doubt but she have mild symtoms and her city severity index is 6/40. One of the doctors prescribed her Ecospirin while the other told not to take it i am not sure what to do and whom to get in touch for the same. Can someone please help me with it
