Central control of cardiorespiratory interactions in fish
Acta Histochemica, 2009 Fish control the relative flow rates of water and blood over the gills in order to optimise respiratory gas exchange. As both flows are markedly pulsatile, close beat-to-beat relationships can be predicted. Cardiorespiratory interactions in fish are controlled primarily by activity in the parasympathetic nervous system that has its origin in cardiac ...

Cardiorespiratory interactions during three different temperatures – a case report
, 2020 Our study explored the cardiorespiratory interactions during three different ambient temperatures. We established coupling functions of cardiorespiratory interactions by applying dynamic Bayesian inference to investigate if and how thermoregulation ...

Variability of cardiorespiratory interactions under different breathing patterns [PDF]
Biomedical Signal Processing and Control, 2022 Abstract The breathing dynamics often change in time and cause different variations in the cardiorespiratory interaction. There exist various breathing patterns, among them one critically important is the variability of the breathing frequency. We investigated the respiratory and the coupled cardiorespiratory system under controlled time-varying ...

Time-variability of cardiorespiratory interactions
2020 11th Conference of the European Study Group on Cardiovascular Oscillations (ESGCO), 2020The cardiorespiratory interactions are important physiological phenomenon, but often their time-variability makes the analysis difficult. Here we present the results of applying a procedure for optimal determination of the time window and method parameters, based on dynamical Bayesian inference. This was applied on cardiorespiratory measurements of one

Synchronization in noisy systems and cardiorespiratory interaction
IEEE Engineering in Medicine and Biology Magazine, 1998In this article, we restrict ourselves to an understanding of the synchronization phenomenon as an adjustment of rhythms of two weakly interacting self-sustained oscillators. We describe a unified approach to synchronization of noisy and chaotic systems and demonstrate that this approach can be used to address the inverse problem of identification of ...

Cardiorespiratory Interactions in Patients with an Artificial Heart
Anesthesiology, 1990A retrospective analysis of the influence of respiration was carried out in three patients with artificial hearts. During spontaneous ventilation, large swings in intrathoracic pressure can produce a pattern reminiscent of pulsus paradoxus in the systemic arterial pressure.
