title = "Quantifying fractal dynamics of human respiration: Age and gender effects",
abstract = "Fractal scaling properties of human respiratory dynamics were quantified and the effects of gender and physiological aging on these factors were determined. Continuous respiratory datasets were collected from 40 healthy adults during 120 min of spontaneous breathing. The interbreath interval time series were extracted by an algorithm and fractal scaling exponents that quantify power-law correlations, were computed using detrended fluctuation analysis. Results indicated evidence for fractal organization in physiologic human breathing cycle dynamics, and for their degradation in elderly men.",
