Flowing blood has no time to oxidize. While you can mess about with red dye
during the clinical exam it would be useless during a FEES.

That's exactly the reason for using red dye - blood
oxidizes, dye can't so the color of the aspirate
oesn't change. I can only assure you, it looks nothing
like blood, in any hue.
