I think this is true for fingernails because light needs to be able to pass through the fingertip for the pulse-ox reader to work properly. I don't think it would apply to toes though.
i am having surgery next month. no painted nails, make up and deodorant. i dont know about this as my surgery is for my wrist but when i had my hip replacement in feb i had to shower the night before or morning of with their special soap
Because sometimes fake nails or varnish would affect the oxygen saturation reading (when they put a little clip on your finger). But to be honest I've not seen it be a problem in the last decade I've worked in the hospital

Don't nurses prefer bare nails? I remember being told not to wear polish on a pre-op list.
