The problem is that that '95' might really be a '90' - surely a drop from 98 to 90 is a cause for concern. If that information is being hidden, it needs to be fixed, regardless of other, more subjective fallback methods.
- JamesBarney 6y agoThe difference of 5% is only common in the 60-70% on some clips. In the 90%-100% level the different is up to 2%-3% on the worst pulse ox's, and usually around 1%. For reference I have two pulse oximeters at home and they routinely give me results that differ by 2-3%. Seems like an issue we should fix, but I don't know what impact this would have in a clinical setting given that they use multiple criteria and the devices are known to be inaccurate.
