Activity Summary

Glycemic control in critically ill patients decreases infection and mortality. Patients receiving vasopressors have altered peripheral perfusion, which may affect accuracy of capillary blood glucose values measured with point-of-care devices.


  • Identify the factors that can affect the accuracy of blood sugar testing.
  • Discuss what blood glucose testing method is acceptable for patients with less than 2, or more than 2 vasopressors.
  • Describe the potential consequences of using an inaccurate blood glucose testing method.
