Capillary refill as an indication of SpO2

One of my coworkers was explaining to me his old basic school taught him that you can use capillary refill time for an indication of the patients SpO2%. Has any one else been taught that? (I’m talking about actual ranges of percentages NOT overall perfusion)

No. My CHD kids can have a brisk cap refill with a sat in the 60s. Patients who are clamped down may have very delayed cap refill and have a good sat.

That's exactly backwards. Cap refill is a rough indicator of perfusion, of which Sp02 is one of the many factors. But it doesn't correlate at all to any range of hemoglobin saturation.

OP it's good that you question and good that you ask, because your coworker is totally wrong.

ummmmm your coworker is wrong.

But I am glad you actually asked someone vs believing his incorrect information as factually correct.

I have never had poor cap refill; I have had SPO2 in to the mid 60's (64% was the lowest I remember, and I was there for a few hours) but I am weird that way.
