Systems, Devices And Methods For Rendering Key Respiratory Measurements Accessible To Mobile Digital Devices

摘要

System and methods for rendering key respiratory measurements accessible to hand-held mobile electronic devices with acoustic input capabilities. A whistle having a pre-determined correlation (between through-flowing airflow per unit time and frequency of acoustic emissions from the whistle) may generate or transmit information or signals. A processor in the mobile electronic device may receive the information or signals, determine a baseline acoustic context, and/or record samples. The processor may determine a frequency value for an acoustic signal (based on the recorded samples), determine an expiratory airflow rate value (based on the frequency value), and determine a respiratory parameter (based on the expiratory airflow rate value). The processor may also determine whether the acoustic signal corresponds to a whistle signal that is generated by a user performing a forceful exhalation through the whistle. The processor may generate and render spirometric information.

主权项

1. A system comprising:
a whistle having a pre-determined correlation between through-flowing airflow per unit time and frequency of acoustic emissions from the whistle; and a mobile electronic device comprising a memory, a microphone, an electronic display, and a processor coupled to the memory, the microphone, and the electronic display, wherein the processor is configured with processor-executable instructions to perform operations comprising:
determining a baseline acoustic context;recording samples via the memory based on information received via the microphone;determining a frequency value for an acoustic signal included in the recorded samples;determining an expiratory airflow rate value based on the determined frequency value;determining a respiratory parameter based on the determined expiratory airflow rate value;generating spirometric information based on one or more of:
the recorded samples,the determined frequency value,the determined expiratory airflow rate value, andthe determined respiratory parameter; andrendering the generated spirometric information.
