Abstract
Provided are concepts for generating an indicator of chronic obstructive pulmonary disease (COPD) in a subject. In particular, an elasticated bag suitable for inflation is utilised, such that a change in a measurable characteristic of the elasticated during exhalation of the subject is detected. The change in the measurable characteristic may be analyzed so as to generate an indicator of COPD. Thus, this indicator may be used by a skilled professional in deciding whether to further investigate the possible presence of COPD.
Claims8
A system for generating an indicator of chronic obstructive pulmonary disease, COPD, in a subject, the system comprising:
- an elasticated bag configured for inflation by exhalation of the subject;
- an information acquisition unit configured to detect a change in a measurable characteristic of the elasticated bag responsive to the subject exhaling into the elasticated bag, the visual characteristic comprising a color property of the elasticated bag;
- and
- a processor configured to analyze the detected change in the measurable characteristic, and to generate, based on the analysis, an indicator of COPD in the subject, wherein analyzing the detected change comprises determining a volume of air and a rate of change of volume of air in the elasticated bag based on a detected change of the color property of the elasticated bag.
