Hi there,
i'm testing this combo and notice, that the sensor is very lazy
(no spikes and a lag time of 20-30min) and sometimes there are no
trend arrows there. My question - is this combo really incompatible
or maybe a bad sensor issue? Did you have such issues sometimes with your G4 receiver, too?
Not sure what you mean by "no spikes and a lag of 20-30 mins". If you mean that when you eat something, you don't see your BG move for 20 to 30 mins, that's how long it takes the body to metabolize the food you eat. And Humalog Insulin (and similar) take 15 mins to start to work, and given the 5 min interval of readings, that could be 20 mins easy before you see insulin start doing it's job. Does that help any?
What i mean is the lag time of a BG meter value and my Dex 7+.
Today, i've noticed big improvements in speed and accuracy.
The trend arrows are always visible, too. Hmm, is the sensor
awaked after two or three days?
Today i've changed the sensor. My conclusion - there's no need for me to buy a
G4 receiver. I can use my 7+ any longer - even with a G4 sensor. So the next
device upgrade for me will be the G5.
All newly installed sensors need a "training period." A good practice is to enter a reading only when the arrow is going straight across. Take several different bG readings throughout the day. It usually takes me most of the first week to train it, and then the second week after a re-start is much more accurate. (By the third week, it usually dies...a victim of hot yoga sweat, I suspect.)
That's about right in my experience.
Accuracy and function in the first 2-3 days is pretty hit and miss. I calibrate frequently (4x a day, twice the required calibrations), and get reasonable numbers from the G4, but nothing I rely on for treatment decision.
Days 3/4 through 21 or so (three weeks) are scary accurate. Enough so that I make insulin administration decisions based on my Dexcom data alone often.
