Estimating the functional age of the respiratory system
The work aimed to develop a mathematical model of the functional age of the respiratory system. 95 practically healthy people aged 29 to 80 were examined. Spirograph parameters were determined on the device "Spirometer MIR Spirobank II" (manufacturer MIR S.r.l., Italy). The most informative indicators of age-related changes in the respiratory system were selected and a formula was obtained that allows to estimate the functional age of this system quite accurately. The average absolute error is 5.28 years.
