This kind of case is not unfamiliar: an emergency girl comes to a young girl, there may be respiratory diseases, we need to put a Nellcor Adapter Cable on her long fingers, but the problem is that 10 fingernails are painted with a bells and whistles, this time SpO2 Is the value obtained reliable? In general, we believe that nail polish will affect the accuracy of SpO2 measurement, but some studies have suggested that the current pulse oximeter may not cause errors, although clinically we will remove nail polish as much as possible.
Interestingly, studies have shown that red, purple, and transparent nail polish have no significant effect on Disposable Spo2 Sensor readings, while blue nail polish has a significant effect on SpO2, and intravenous injection of methylene blue (methylene blue) will also have an effect on SpO2. Significant effects, but dyes are often redistributed or excreted in a matter of minutes, so the effect on SpO2 is temporary, and nail polish will continue to affect the results unless you erase them. Interested friends can practice it on their own.
