Continuous glucose monitoring metrics in pregnancy with type 1 diabetes mellitus

Figure 1 Basic operational mechanism of continuous glucose monitoring sensor measuring interstitial glucose. Med: Artificial redox mediators such as Ferrocene or Ferricyanide, red-reduced form, ox-oxidized form; FAD: Flavin Adenine Dinucleotide; FADH2: Flavin Adenine Dinucleotide, reduced form.

Figure 2 Shows the graphical continuous glucose monitoring metrics during pregnancy. A and B: Recommended metrics for continuous glucose monitoring during pregnancy; C: Illustrates a typical ambulatory glucose profile (AGP) model. When AGP is generated on certain devices, it defaults to standard time-in-range settings for non-pregnant individuals. Therefore, careful interpretation is necessary, or settings should be adjusted to reflect pregnancy-specific parameters prior to generating the AGP.
