Abstract
An apparatus for measuring lung ventilation, comprising: a pressure device to measure volume of air flow; an aerosol-generating device that provides aerosol particles to be released at a determined point in a breathing cycle; a mouthpiece with a detector that measures the concentration of aerosol particles for a given volume during the breathing cycle; and a computing device configured to provide lung ventilation data as a function of time constants.
Claims5
A method for determining the position of an obstruction in the upper region of the lungs, comprising the steps of:
- a. measuring pressure data and calculating volume of airflow of a breathing cycle;
- b. providing a volume of penetration;
- c. providing an aerosol bolus at a determined point of the breathing cycle;
- d. measuring a concentration values of aerosol particles and calculating time constants from the measured aerosol concentration values;
- f. repeating steps b to d using a different volume of penetration;
- and
- g. comparing the calculated time constants, in a processing device, from at least two provided volumes of penetration to determine the position of an obstruction.
