Abstract-

Pressure-induced skin blood flow responses measured via laser Doppler flowmetry are commonly reported in the time domain. The usefulness of spectral analysis in examining blood flow control mechanisms has been demonstrated, but traditional Fourier analysis does not provide sufficient resolution to reveal characteristic low frequencies. Time-frequency (wavelet) analysis was performed on 10 subjects' sacral skin blood flow responses to heating (45 degrees C) with improved resol...

Case reports have described a critical reduction in blood flow when higher concentrations of ropivacaine were used for peripheral-nerve blocks. One hypothesis is that local application of ropivacaine in

(air passage obstruction that causes snoring can also increase the risk of stroke)(Brief Article) Science News ; Surveys have linked snoring to strokes, but they have not revealed the basis for the connection. Now, researchers report that the obstruction of air passages that makes a person snore heavily or snort while sleeping can sharply reduce blood flow to the brain, possibly boosting the risk of stroke.
