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

A method for spirometric measurement using a whistle having a pre-determined correlation between through-flowing airflow per unit time and frequency of acoustic emissions from the whistle, the method comprising:

• determining, via a processor of a mobile electronic device, a baseline acoustic context;
• recording samples based on information received via a microphone of the mobile electronic device;
• 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, and
• the determined respiratory parameter;
• and
• rendering the generated spirometric information.
