Wavelet phase synchronization between BP and MCAv, with P_ETCO₂ as an additional input. (A) PSI against corresponding pseudo-frequencies (representing the result of wavelet scale to frequency conversion). (B) Patient (affected and unaffected hemispheres) versus control comparisons for mean PSI. BP, blood pressure; MCAv, middle cerebral artery flow velocity; P_ETCO₂, partial pressure of end-tidal CO₂; PSI, phase synchronization index; VLF, very low-frequency; LF, low-frequency; HF, high-frequency.
