Well your comment that you can't detect asthma exacerbation did threw me and surprise other didn't pick this up. The spirometry is used to detect the severity of the attack for asthma and COPD, hence if you have a convenient device that's easy to use for monitoring you can actually estimate how much medication you need to take or go to the ED if the exacerbation gets worst. Hence why I was very interested if Wheezo was tested against the spirometry (actually management confirmed that the previous version was.......).
