Interferences between baroreflex and respiration. Evaluation by symbolic analysis and conditional entropy
1Dipartimento di Bioingegneria, Politecnico di Milano, Piazza Leonardo da Vinci, 32, 20133 Milano, Italy.
Background:
The baroreflex is one of the most important short-term cardiovascular autonomic control mechanisms. Its interactions with other reflexes, mainly cardiopulmonary reflexes, are of paramount importance in controlling heart rate.
Objectives:
This study assesses the coupling between baroreflex and respiration during a progressive bicycle mild dynamical exercise.
Methods:
The coupling was assessed by symbolic analysis and conditional entropy.
Results:
Findings suggested the close relationship between the baroreflex sequences and the phase of respiratory signal and, thus, the interference between baroreflex and cardiopulmonary reflexes.
Conclusions:
Indexes describing baroreflex based on spontaneous variability are strongly affected by cardiopulmonary influences.

Physiology of Respiration II: Neurogenic Control of Respiration
Central Control
The brainstem is the primary site of central control, hosting respiratory centers:

CO2 has a potent influence on respiration and is strictly regulated. Under...
Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
Alterations in Respiration II
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...
