title: [Estimation of SIDS with measurement of cardio-respiratory contribution ratio through multivariate autoregressive modelling approach].
abstract: We obtained the cardio-respiratory impulse response and noise contribution ratio to study the central respiratory control system in one case of Ondine's curse, one case of sleep apnea syndrome and 34 cases of preterm infants, using multivariate autoregressive analysis. In Ondine's curse, the noise contribution ratio decreased during sleep. In the sleep apnea syndrome, the noise contribution ratio before apnea and after apnea decreased. In the preterm infants, the noise contribution ratio increased with the conceptional age. From these results, we concluded that the central cardio-respiratory control system was disturbed in Ondine's curse, sleep apnea syndrome and preterm infants. The cardio-respiratory impulse response using a multiple autoregressive analysis was useful for prediction of sudden infant death syndrome.
