Seems although ISN's product would be usefull there are already products out there for sale which do the exactly same thing for these.

Thake this device for example.

Digital Peak Flow Meter

what does it do??? Pretty much exactly what the wheezometer does..

Benefits:

Measurements with a peak flow device can help both the patient and doctor to monitor the disease and can help determine the effectiveness of medications and therapies. In addition, a peak flow measurement can help when asthma or COPD (Chronic Obstructive Pulmonary Disease) disease state is getting worse. A patient’s peak flow and FEV-1 may show changes before the patient recognizes any symptoms and can allow a physician to adjust a patient’s treatment to prevent dangerous episodes that could require hospitalization or may be life threatening.

"An important way to monitor lung function for the warning signs that often exist before a crisis is to use a device like the Microlife Digital Peak Flow Meter that measures both peak expiratory flow (PEF) and Forced Expiratory Volume in 1-Second (FEV-1). Indicates early warning signs for impending asthmatic incidents allowing user and physician to adjust medication dosage accordingly. Easy to use and fits inside a backpack, purse or briefcase."

It also comes with software like ISN's product.

So you get the same product for a fraction of the price.

Its currently for sale for $75.50 including softwear or $49.50 without the software.
