Target Behavior¶

High Temp Target Raises Sensitivity¶

Default: OFF

When this feature is enabled, manually setting a temporary target above 100 mg/dL (5.5 mmol/L) will decrease the Sensitivity Ratio used for ISF and basal adjustments, resulting in less insulin delivered overall. This scales with the temp target set; the higher the temp target, the lower the Sensitivity Ratio used.

If Half Basal Exercise Target is set to 160 mg/dL (default), a temp target of 120 mg/dL uses a Sensitivity Ratio of 0.75. A temp target of 140 mg/dL uses a Sensitivity Ratio of 0.6.

Low Temp Target Lowers Sensitivity¶

Default: OFF

When this feature is enabled, setting a temporary target below 100 mg/dL (5.5 mmol/L) will increase the Sensitivity Ratio used for ISF and basal adjustments, resulting in more insulin delivered overall. This scales with the temp target set; the lower the temp target, the higher the Sensitivity Ratio used.

If Half Basal Exercise Target is set to 160 mg/dL (default), a temp target of 95 mg/dL uses a Sensitivity Ratio of 1.09. A temp target of 85 mg/dL uses a Sensitivity Ratio of 1.33.

Sensitivity Raises Target¶

Default: OFF

Enabling this feature causes Trio to automatically raise the targeted glucose if it detects an increase in insulin sensitivity. If Sensitivity Ratio is \(\gt 1\), target glucose will be increased.

Resistance Lowers Target¶

Default: OFF

Enabling this feature causes Trio to automatically lower the targeted glucose if it detects resistance to insulin. If Sensitivity Ratio is \(\lt 1\), target glucose will be decreased.

Half Basal Exercise Target¶

Default: 160 mg/dL
Setting Limits: 100-300 mg/dL

The Half Basal Exercise Target allows ou to scale down your basal insulin during exercise or scale up your basal insulin when eating soon by setting a manual temp target. To scale down for exercise, set a temp target above 100 mg/dL. To scale up for eating soon, set a temp target below 100 mg/dL.

For example, at a temp target of 160 mg/dL, your basal is reduced by 50%, but this scaled depending on how far away from 100 your temp target is set.

• Temp Target \(= 160\) mg/dL: \(50\)% reduction in profile basal
• Temp Target \(= 140\) mg/dL: \(60\)% reduction in profile basal
• Temp Target \(= 120\) mg/dL: \(75\)% reduction in profile basal

You can see how adjusting this setting will influence your profile basal when you set a temp target in Trio. On the screen, you will be able to set a custom Half Basal Exercise Target for the duration of the temp target you set.
