What Makes Tandem Pumps Different? The Power of Control-IQ+
At the heart of every Tandem pump is a smart system called Control-IQ+ technology. Think of it as a helpful co-pilot for your diabetes management. Here’s what it does:
- Predicts the Future: It uses data from a compatible Continuous Glucose Monitor (CGM) to predict where your glucose levels will be 30 minutes from now.
- Acts Automatically: Based on those predictions, it automatically adjusts your background (basal) insulin delivery. If it sees you’re trending high, it gives you a little more insulin. If you’re heading low, it reduces or stops insulin.
- Delivers Correction Boluses: If you forget a meal bolus or miscalculate carbs, Control-IQ+ can give you an automatic correction bolus to help bring high glucose levels back into range.
The goal is to help you spend more time in your target glucose range, with fewer highs and lows. Many users find this automation helps them sleep better at night and takes some of the constant mental load off of managing diabetes.
Compatibility with Leading CGMs
Tandem pumps are designed to work seamlessly with today’s most popular CGM systems, giving you flexibility. They are compatible with:
- Dexcom G6 & G7
- FreeStyle Libre 2 Plus & 3 Plus Sensors
This integration is what allows the Control-IQ+ technology to work its magic. The CGM sends glucose readings to the pump every few minutes, giving the system the data it needs to make smart, automated decisions about your insulin.
Choosing Your Tandem Pump: t:slim X2 vs. Tandem Mobi
Tandem offers two excellent pumps that share the same core technology but have different designs to fit different lifestyles. Let’s compare them.
Tandem t:slim X2 Insulin Pump
The t:slim X2 is a proven and popular choice. It’s known for its reliability and user-friendly design.
Key Features:
- Color Touchscreen: All controls are managed through a bright, easy-to-read touchscreen right on the pump.
- Larger Reservoir: It holds up to 300 units of insulin, which is ideal if you require more insulin or want to go longer between cartridge changes.
- Remote Software Updates: You can update the pump’s software from home, so you always have the latest features without needing a new device.
- Established Track Record: The t:slim X2 has been trusted by hundreds of thousands of users for years, and its Control-IQ technology has strong clinical results.
Who is the t:slim X2 best for?
The t:slim X2 is a great fit for anyone who wants a reliable, all-in-one device with a proven track record. It’s suitable for both adults and children (ages 2 and up), and its larger insulin capacity is a major plus for many.
Tandem Mobi Insulin Pump
The Tandem Mobi is one of the newest and smallest automated insulin pumps available. It’s designed for discretion and flexibility.
Key Features:
- Incredibly Small: At about half the size of a traditional pump, the Mobi is so small you can clip it to a collar, slide it into the coin pocket of your jeans, or wear it in an adhesive sleeve.
- Smartphone Control: You can control the pump entirely from a compatible iPhone, including delivering boluses. A physical button on the pump also allows for quick bolusing without your phone.
- Flexible Tubing: It features a very short (5-inch) tubing option, giving you the feel of a patch pump with the flexibility of a tubed one.
- Wireless Charging: It uses a wireless charging pad, so you don’t have to plug it in.
Who is the Mobi best for?
The Tandem Mobi is perfect for active users, people who prioritize discretion, or anyone who loves managing their life from their smartphone. It gives you the power of Control-IQ+ in a tiny, modern package.
