Abstract

The article deals with thethermo physical model of air flow energy exchange forinhalation and exhalation, which uses turbulence properties. On the base ofthis model,measurement sensors and calculation methods can be built for air flow parameters, characterizing volume of the lungs and speed of air flow. Impaired lung function and cardiovascular system affect the parameters of air flow. Research results form the basis for design of air flow parameters sensorand development of algorithms for portable devices functional diagnostics.


Keywords: breath, condition monitoring, turbulence, auscultation, recovery, convective heat exchange
