Would you have symptoms if your blood oxygen level truly jumped around from 97 to 84 in a minute and then back up? what causes that? its happened several times with a finger pulse oximeter. is that probably an error? 30 year old. 3 weeks postpartum.

About that machine: A finger pulse oximeter is a little machine that has a specific purpose. Normal, healthy people neither have nor use the machine unless there is a specific reason. For example, a pilot might use one to watch for the downward trend as he flies higher and higher in his little 2-seater. Numbers that jump around don't have a meaning unless the person has been asked by her doctor to watch for that.
