{CGM} DexCom G4 Platinum Has LONG Range…most of the time.

by Leighann on March 4, 2013

In the spring of 2012 we had a trial of the Medtronic CGM* and subsequently began using the DexCom 7+ CGM in the summer. In late 2012 we ordered the DexCom G4 Platinum.

One of the reasons why we wanted to upgrade to the G4 after only recently starting the 7+ was for the increased range. With the 7+ she needed to keep the receiver on her body or close to it. The G4 boasts a range of up to 50 feet.

We put it to the test this winter when Q played basketball and participated in a musical production. It was very nice to have the receiver in my hand and be able to glance at the graph and number while she was across the room, rather than guessing.

On the afternoon of her last musical performance, we accidentally left the receiver on the kitchen counter…something we’ve never done before! I kept glancing down at my waist (I had clipped the receiver to my belt loop during practices and performances using the TallyGear case–review tomorrow!) and was dismayed to see it wasn’t there. She was 167 right before the performance began and I didn’t know if she was dropping or rising…wow, how much we have come to depend on that contextual knowledge!

The G4 always kept her in range while at musical practice.

Basketball was a little more hit or miss. I’m not sure if it was the construction of the church rec room where they practiced or what, but sometimes it would lose range, particularly during half time when they would have a chat at the other end. During sports is exactly when we need the CGM. If it lost signal, it would usually pick back up on its own.

Overall, I’ve been pleased with the longer range that the G4 gives over the DexCom 7+ and the Medtronic, both of which had to remain on her person in a waist pack during the day.

Come back tomorrow as I tell you about one of the new carrying options for the CGM receiver we’ve discovered. Not only can she use it, but us parents can use it, too.
