The (human) respiratory rate at rest

Journal of Mathematical Biology, 2022
AbstractAll schoolchildren know how often they breathe, but even experts don’t know exactly why. The aim of this publication is to develop a model of the resting spontaneous breathing rate using physiological, physical and mathematical methods with the aid of the principle that evolution pushes physiology in a direction that is as economical as ...

Evolution of cardiorespiratory interactions with age [PDF]

, 2013
We describe an analysis of cardiac and respiratory time series recorded from 189 subjects of both genders aged 16–90. By application of the synchrosqueezed wavelet transform, we extract the respiratory and cardiac frequencies and phases with better time ...

The natural history of respiratory syncytial virus in a birth cohort : the influence of age and previous infection on reinfection and disease [PDF]

, 2012
This study aimed to quantify the effect of age, time since last infection, and infection history on the rate of respiratory syncytial virus infection and the effect of age and infection history on the risk of respiratory syncytial virus disease.
