poor signal quality

[tiredandscared]

I've been having some really crazy fluctuations with my SPO2 meter. I've had nights where my oxygen desaturations have gone as low as 73. But they've all been low-signal quality. Does anyone have any idea whether this is just noise? The times i enforce the SPO2 probe with medical tape. It never seems to go lower than 87.

These spots look like this. Any idea? Can I just discard them as unreliable?

When you have poor signal quality the readings are not accurate. It means that it is not receiving a strong pulse which could be caused by probe placement, cold hands, or anything that would decrease circulation such as sleeping on your arm. You might try placing it on another finger.
