US 2025/0359843 A1 · LUNG FUNCTION TESTING

Abstract

Methods are disclosed for determining an optimal distance between an electronic device and a user providing an audio sample of a respiratory manoeuvre for use in assessing the lung function of the user. An audio sample dataset comprising a plurality of audio samples of respiratory manoeuvres performed by the user at a plurality of distances between the electronic device and the user is received from an audio sensor in the electronic device. The audio sample dataset is analysed to determine an optimum audio sample of a respiratory manoeuvre for use in assessing the lung function of the user. The optimum distance corresponding with the optimum audio sample is determined. The user is instructed to place the electronic device within a threshold distance of the optimum distance and perform a respiratory manoeuvre. Audio samples of the respiratory manoeuvre at the optimum distance can be used in assessing user lung function.

Dependent claims

A computer-implemented method of obtaining an audio sample of a respiratory manoeuvre for use in assessing the lung function of a user, the computer-implemented method comprising:

determining a minimum area of an open mouth of the user required for providing an optimum audio sample of a respiratory manoeuvre for use in assessing the lung function of the user;
receiving, from a user-facing camera in an electronic device, image data of the user's face including at least an open mouth of the user;
identifying, from the image data, an area defined by the open mouth;
determining whether the area of the open mouth from the image data is at least equal to the minimum area of the open mouth required for providing the optimum audio sample of the respiratory manoeuvre;
and
guiding the user to achieve the optimum open mouth shape, wherein guiding the user comprises providing an indication whether the area of the open mouth of the user is at least equal to the minimum area of the open mouth required for providing the audio sample of the respiratory manoeuvre;
wherein upon determining, from the image data, that the area of the open mouth is at least equal to the minimum area of the open mouth required for providing the audio sample of the respiratory manoeuvre, instructing the user to perform a respiratory manoeuvre;
and
receiving, from an audio sensor in the electronic device, an audio sample of the respiratory manoeuvre.
