Can O2 saturation assessed through NIRS present negative values?

I am computing O2 saturation levels as the rate between HbO and HbT (HbO/HbT) recorded through fNIRS. While most of the outputs range between 0-1, I have some negatives values and also some values...

When increasing NIRS acquisition sampling (e.g: from 10 to 20Hz), is it necessary to add an additional pre-processing step to the filtering?

Hi all, In a first experiment we have been recording nirs data with a sampling frequency of 10 Hz. To correct from movement artefacts and so on we have applied the typical band pass filter [0-3]....

How to compute concentration changes in oxidised cytochrome c oxidase (∆ [oxCCO]) from a signal acquired using NIRS?

fNIRS provides a measure of cerebral O2 delivery by monitoring concentration changes in oxygenated ∆[HbO2] and deoxigenated ∆[HHb]). Concentration changes in (∆ [oxCCO]) can be derived with...
