Abstract
According to an aspect there is provided a method of determining the health of a subject, the method comprising determining the absolute humidity and volume of air exhaled by the subject over time; and analysing the determined absolute humidity and volume of air exhaled by the subject to determine a characteristic of the air that was above the isothermic saturation boundary, ISB, of the subject.
Claims16
A method of determining the health of a subject, the method comprising:
- determining the absolute humidity and volume of air exhaled by the subject over time during exhalation;
- and
- analysing the determined absolute humidity and volume of air exhaled by the subject to determine a characteristic of the air that was in the respiratory system of the subject above the isothermic saturation boundary, ISB, before exhalation:
- wherein the ISB of the subject is the point in the respiratory system of the subject where inhaled air reaches body temperature and is completely saturated, with water.
A non-transitory computer readable medium comprising computer readable code, the computer readable code being configured such that, on execution by a suitable computer, processor or control unit, the computer, processor or control unit is caused to;
- determine the absolute humidity and volume of air exhaled by the subject over time during exhalation;
- and
- analyze the determined absolute humidity and volume of air exhaled by the subject to determine a characteristic of the air that was in the respiratory system of the subject above the isothermic saturation boundary, ISB, before exhalation;
- wherein the ISB of the subject is the point in the respiratory system of the subject where inhaled air reaches body temperature and is completely saturated with water.
A device for determining the health of a subject, the device comprising:
- a control unit configured to determine the absolute humidity and volume of air exhaled by the subject over time during exhalation;
- and analyse the determined absolute humidity and volume of air exhaled by the subject to determine a characteristic of the air that was in the respiratory system of the subject above the isothermic saturation boundary, ISB, before exhalation;
- wherein the ISB of the subject is the point in the respiratory system of the subject where inhaled air reaches body temperature and is completely saturated with water.
