Embodiment Construction

[0073] The present disclosure relates to a method for measuring a respiratory parameter, and more particularly, to a method for inferring (eg calculating) a lung function parameter by using measured and / or known input parameters.

[0074]Absolute lung volume (ALV) is an example of a lung function parameter and is a generic term used to include individual absolute lung volume compartments, which include TLC, FRC, TGV, and RV. ALV is a key parameter in lung physiology and diagnosis, but is not easily measured in living individuals. While conventional techniques for measuring absolute lung volumes in humans are considered acceptable in many situations, such techniques may produce undesired measurement inaccuracies, may require complex and / or expensive equipment, or may be difficult implement.

[0075] Devices for measuring ALV must have clinically acceptable accuracy and precision, especially for subjects with respiratory disease. Clinically acceptable margins of error are defi...

Abstract

A pulmonary measurement system includes a pulmonary measurement device that includes a mouthpiece with an airflow path and a sensor positioned in the airflow path; and a controller communicably coupled to the sensor. The controller includes a processor and instructions stored in memory and is operable to execute the instructions with the processor to perform operations including identifying a measurement from the sensor; identifying a particular equation stored in the memory, the particular equation developed using data analytics and including an input parameter that is based on the identified measurement; and based on the identified measurement and the particular equation, determining a value of absolute lung volume.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 844182, filed July 9, 2013, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to methods of deriving (eg, calculating) respiratory health parameters and / or methods of deriving (eg, calculating) lung function parameters by using measured and / or known input parameters. Background technique [0004] Absolute lung volume is a key parameter in lung physiology and diagnosis, but its measurement in living individuals is not easy. It is relatively simple to measure the amount of air exhaled from the subject's mouth, but at the end of a complete exhalation, a significant amount of air remains in the lungs because the mechanical properties of the lungs and chest wall (including the ribs) do not allow the lungs to collapse completely. The gas remaining in the lungs at the end of a complet...
