Just Breathe On Your Phone To Make Sure Your Lungs Are Healthy

Developed by researchers at the University of Washington to replace spirometers -- devices used by doctors to measure lung capacity and diagnose respiratory conditions -- SpiroSmart is a simple app that costs thousands of dollars less than dedicated hardware. So it's affordable and easy to use by patients who can monitor their conditions at home by simply exhaling on their phones.

A spirometer can measure how badly your asthma, etc, is affecting your airways by simply measuring etc the speed and volume of air as someone blows into a tube.

But SpiroSmart takes a different approach to avoid the need for extra hardware. The researchers modelled a human trachea and vocal tract and used that to generate an algorithm which can analyse the sound of someone's breath as it resonates inside their lungs. The sound and resonance changes as the flow of air is restricted, and the app is able to detect this, providing a doctor with everything they'd need to know to make a diagnosis. Surprisingly, the app, which could be given away for free, is just as accurate as dedicated spirometers. And patients don't have to push themselves to the point of exhaustion just to get an accurate reading. [Ubiquitous Computing Lab - University of Washington via Medgadget]

    could be given away......

      i noticed that too...

      its funny because i suffer, and this would be very useful for me - but i won't be holding my breath for decent price (pun not intended)

    Is this not yet available? And does the could be given away hint that when it is available it may be free? I could really use this for my seven year old, who suffers from asthma, to gauge severity.
