The data-based model of interaction between the respiratory and cardiovascular systems

Respiration and heart rate continuously interact, and in the following, we are looking for variations in RR-intervals, systolic, and diastolic blood pressure caused by different phases of breathing. We propose a data-based model of interaction in the cardio-respiratory system, which is driven by breathing phases. The model reveals the desired properties of RR, SBP, and DBP signals, and is a promising starting point for a new data-based stochastic model of the cardio-respiratory system.
