1. A health risk assessment device comprising:
- a mouthpiece;
a flow path in fluid communication with the mouthpiece;
a sensor disposed in the flow path and configured to generate a signal representative of a dynamically changing air flow in the flow path provided by a user through the mouthpiece;
a user interface configured to allow the user to provide an age of the user; and
a processor coupled to the sensor and configured to;
digitally filter the signal representative of the dynamically changing air flow to generate flow data for the dynamically changing air flow;
implement a test to evaluate the flow data, the test determining time elapsed to reach peak flow;
evaluate the flow data to validate that the dynamically changing air flow is qualified for spirometric parametric determination based on the test;
integrate the flow data to determine a volume for the dynamically changing air flow; and
determine spirometric data for the air flow based on the volume;
wherein the processor is further coupled to the user interface and configured to determine an output specifying a lung age gap based on the spirometric data and the age of the user.

Abstract
A health risk assessment device includes a mouthpiece, a flow path in fluid communication with the mouthpiece, a sensor disposed in the flow path and configured to generate a representation of a spirometric parameter of air flow in the flow path exhaled by a user through the mouthpiece, a user interface configured to allow the user to provide user profile data including smoking history data, and a processor coupled to the sensor and the user interface and configured to determine an output indicative of a risk that the user develops a respiratory, cardiopulmonary, or cardiovascular disease based on the spirometric parameter representation and the smoking history data.
