Take a look at this blood pressure cuff that connects directly to an iPod Touch, an iPhone, or an iPad. The data is stored and displayed on your own device, but the data is also sent to the manufacturer (Withings), where it can be shared with a health care professional. I'm not too excited about sharing my health information with a software firm, but what is important is that many of the standard diagnostic tools available to health care professionals are about to make managing your own health much easier, as well as giving you the tools to give your doctor much better information about your health. Doctors may be subscribing high blood pressure medicine based on just a few BP readings taken days apart, in the office, where the "white coat" effect on blood pressure is well known (your blood pressure is typically higher in the doctor's office, where you may be nervous about negative results). Compare that approach to health care to being able to easily take daily BP readings over a period of weeks or months to give a much better look at overall blood pressure. Couple this cuff with devices that reads blood sugar, heart rate, blood oxygen levels, and some other blood tests, and it will be possible to spend much less on doctor visits while actually getting better diagnoses.
