    ..Thus, other endothelial mechanisms, such as endothelium-derived hyperpolarizing factor (EDHF), might be involved in the regulation of this sixth frequency interval (0.005-0.0095 Hz)...

    Svein Aslak Landsverk
    Department of Anesthesiology, Ulleval University Hospital, Oslo, Norway
    Anesth Analg 105:1012-9, table of contents. 2007
    ..We hypothesized that wavelet transform of laser Doppler flowmetry signals could detect changes in the microcirculation induced by general anesthesia, such as alterations in vasomotion and sympathetic activity...

    Department of Anesthesiology, Ulleval University Hospital, Oslo, Norway
    Anesthesiology 109:849-55. 2008
    ..Based on knowledge of slow oscillation in skin blood flow, the authors hypothesized that the variability of DeltaPOP would be larger than that of DeltaPP when calculations were performed continuously over a long recording period...
