Blood oxygen saturation vs hematocrit?

[20sam91]

Do these two have any correlation? I bought a home hemoglobin monitor and can't get a consistent reading out of it no matter what. I've spent $40 on strips and have finally given up. I've seen you can buy oximeter's which seem to have less moving parts so I would hope less to go wrong. Would these be of any use in trying to determine where my hct is at?
