睡眠深度と脈波伝搬時間の関係について

抄録

In order to analyze the autonomic functioning during sleep, all night polygraphic measurement including the pulse transit time (PTT) was carried out with healthy subjects under sleep deprived and natural sleep condition. Sleep stages were classified based on the EEG recordings. Average and standard deviation of the PTT were calculated in each segment. Effect of sleep deprivation on the autonomic function was investigated.
