Respiration rate change induced by controlling the phasic relationship between melodic sound and respiration
Abstract:
It has been suggested that the phasic relationship between sound and respiration (PRSR) is important. However, the effect that the relationship has on respiration rate is rarely studied. Here, by using our invented interface, we have developed a method of systematically controlling the PRSR and show that the respiration rate can be changed by controlling the PRSR. In concrete, when realized error of PRSR is large, respiration rate significantly increased. Since the effect appears with participants listening passively to melodic sounds without any instruction, the result could be utilized as a tool for managing everyday stress.

A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
01:23Physiological 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...
