RE: [IPk] Re: What is the FreeStyle NavigatorT Continuous Gluc ose Monitor

Hi Lesley,

I've seen several presentations on the Navigator and thing that really 
impresses me is that it would detect the rate of glucose change and notify 
the wearer if glucose were dropping quickly even if the blood glucose level 
were still above the level for symptomatic hypoglycemia. The idea is like 
having a petrol gauge on a car: if you notice you're running low on petrol 
before the car actually runs out of fuel, you can prevent the car stopping 
suddenly on the road. We're practically running on fumes by the time we get 
the symptoms of hypoglycemia. If I got a little alert when my bg were rising 
or falling by 2 or more mg/dl per minute, I'd be able to head off high 
glucose excursions at the pass and adjust my pump's basal rate before acute 
hypoglycemia. That's where the Navigator folks are going in their emphasis 
on the clinical utility of the technology.

Also, it has to be said that fingersticks are several minutes behind and 
+/-10% compared to venous blood glucose measurements...just because we 
consider fingerstick bg measurement the gold standard for home use now 
doesn't mean they'll always be the most valuable tooks in our kit. Look at 
what happened to urine glucose testing....

How's the Dia-Port goin'?

All best,
