Bland-Altman plots of spectral domain BPV parameters derived from EndoPAT and Finometer devices. Bland-Altman comparison of frequency-domain BPV parameters between EndoPAT- and Finometer-derived time series shows low agreement between the two devices — across VLF, LF, and HF spectral ranges for both absolute and relative BPV. However, relative LF and absolute HF BPV demonstrate greater accuracy relative to other BPV measures.
