Sensor System for Analyzing Human Respiration in Arctic Conditions

Abstract

A sensor for monitoring the dynamics of changes in the concentration of carbon dioxide in humans during respiration is presented. The sensor is based on a matched pair of LED-emitter-receiver. It was revealed that the shape of the nasal cavity affects the hydrodynamics and heat transfer in the respiratory system. It has been shown that dynamic parameter analysis is necessary for the diagnosis of respiratory diseases.
