IR is insulin resistance and %β is the β-cell function (more precisely, an index for glucose tolerance, i.e. a measure for the ability to counteract the glucose load). Insulin is given in μU/mL. [7] Glucose and insulin are both during fasting. [2] This model correlated well with estimates using the euglycemic clamp method (r = 0.88). [2]
When data were graphed, it was obvious that a linear regression with an intercept of 60 and a slope, or multiplier, of 0.02 could resolve the complexity of the orders of White et al. to a single formula for calculation of intravenous insulin requirements: (blood glucose − 60) × 0.02 = insulin dose/h. [3]
Basal insulin is provided as a once or twice daily injection of dose of a long-acting insulin. In an MDI regimen, long-acting insulins are preferred for basal use. An older insulin used for this purpose is ultralente, and beef ultralente in particular was considered for decades to be the gold standard of basal insulin.
Example 4 evaluates the delivery from an insulin pump, showing blood glucose plots along the top, carbohydrates eaten (bubbles in the middle of the chart), basal and bolus insulin delivered at the bottom. This is a good example of the flexibility in lifestyle afforded to an insulin pump user as carbohydrates are not "scheduled" to match insulin ...
An insulin pump and wristop controller is one way to arrange for a closely controlled basal insulin rate. The slow-release insulins (e.g., Lantus and Levemir) can provide a similar effect. In healthy individuals, basal rate is monitored by the pancreas, which provides a regular amount of insulin at all times.
How to Calculate a Calorie Deficit. ... you can use a formula that accounts for your basal metabolic rate ... By helping the body use insulin more effectively, metformin may decrease hunger and ...
In general, all algorithms do the same basic functionality of taking in CGM data and based on predicted glucose level's and the user's personal settings (for basal rates, insulin sensitivity, and carbohydrate ratio, for example) then recommends insulin dosing to help bring or maintain glucose levels in target range.
The hyperglycemic clamps are often used to assess insulin secretion capacity. Hyperinsulinemic-euglycemic clamp technique: The plasma insulin concentration is acutely raised and maintained at 100 μU/ml by a continuous infusion of insulin. Meanwhile, the plasma glucose concentration is held constant at basal levels by a variable glucose infusion.
