title: [Adaptive wavelet analysis of oscillations of the cutaneous peripheral blood flow in human].
abstract: The main principles of the method for the spectral timing analysis of the peripheral blood flow oscillations, obtained by laser Doppler flowmetry, have been presented. The method allows one to investigate the oscillations in a wide frequency range both in stationary and nonstationary conditions during the performance of functional tests. The potential of the method has been demonstrated in experiments with the reaction of the microvascular bed to the transcutaneous iontophoretic introduction of an acetylcholine chloride solution. The major advantage of the method as compared to the traditional wavelet analysis is a significant increase in the "effective" length of the signal analyzed. This allows a correct analysis of the low-frequency component of much shorter LDF recordings than those used in the traditional wavelet analysis.
