Integration of BGM/CGM into Automated Insulin Delivery (AID)

Introduction

Automated Insulin Delivery (AID) systems combine Continuous Glucose Monitors (CGM) and insulin pumps to automate dosing. Blood Glucose Meters (BGM) serve as the critical safety reference.

Key Considerations

• Factory-calibrated sensors in modern AID systems rely on BGM during failures or warm-up periods.
• Calibration errors pose a significant risk, potentially leading to insulin overdose or suspension.
• High-accuracy strips are essential to mitigate this risk.

Manufacturer Ecosystems

Pump manufacturers create restricted ecosystems, allowing only specific Bluetooth-enabled meters to communicate directly with the pump.

• Ascensia Contour is a prime example.

Physiological Lag Considerations

Integration of BGM/CGM into AID systems subjects test strips to physiological lag constraints, similar to sensor accuracy during rapid glucose changes.

Conclusion

In conclusion, integrating BGM/CGM into AID systems is crucial for accurate insulin dosing. High-accuracy test strips and restricted manufacturer ecosystems help mitigate risks associated with calibration errors and physiological lag.
