Application of Continuous Glucose Monitoring System (CGMS) and Patient Education

  • 1Diabetes Center, The Catholic University of Korea Bucheon St. Mary's Hospital, Bucheon, Korea. ygkang@catholic.ac.kr


The use of a Continuous Glucose Monitoring System (CGMS) allows diabetic patients to adjust their own insulin doses, food intakes and physical activities and to thus improve glycemic control. Even though we check the SMBG more than 4 times per day, we can't find a hidden abnormal blood glucose. CGMS have been devised to assist in the diagnosis and treatment of blood glucose changes using computer analysis. The objective of this report is to summarize the measurement principles, application and patient education of CGMS.

  • Fig. 1. Difference in the change in HbA1c level from baseline to the 12-week follow-up examination between the self-monotoring blood glucose (SMBG) and Guardian continuous glucose monitoring system (Guardian RT) groups. Black bars represents baseline HbA1c and white bars represent HbA1c levels 12 weeks later.
