Breathing patterns may confound autoregulation metrics above 0.08 Hz; leaves open standardized respiratory protocols for future studies.
Do controlled breathing patterns alter cerebrovascular autoregulation assessments in healthy volunteers?
Breathing rate, rhythmicity, and end-tidal CO2 levels significantly influence cerebral autoregulation assessments and must be accounted for in physiological studies.
Eames et al. (2004) studied this question.
