Optical oxygen saturation estimate
An estimate of blood oxygen saturation derived from optical measurements
Hypotheses on this target 1
Telling states apart1
Direct measurement
Indicator replacement
Telling states apart1
Widening blood vessels creates an apparent oxygen loss at skin repair sites
Where this hypothesis actsRepair sites during local vasodilation under matched heat and pressure
What is proposedDistinguish optical sampling effects from genuine tissue oxygen deficits
With whatInstrument or assay
HowPair depth-sensitive optical measurements with independently calibrated tissue-oxygen measurements; record temperature, pressure, depth, and vascular volume
Possible resultExpected separation of apparent saturation declines from genuine oxygen deficits and functional repair failure
