Evidence-based guidelines from the Academy of Nutrition and Dietetics recommends education on carbohydrate counting using insulin-to-carbohydrate ratios (ICRs) for persons taking multiple daily insulin injections or insulin pump therapy.

The Insulin Sensitivity Factor (ISF) is sometimes also called the correction factor. It reflects the power of a unit of insulin in the body. The ISF indicates how much 1 unit of rapid-acting insulin may drop a blood glucose level (BGL).

胰岛素敏感性因子（ISF），也常称为校正因子，是用来衡量体内一单位速效胰岛素降低血糖水平（BGL）的能力。 如果ISF为1:2.0 mmol/L，那么每降低2 mmol/L的血糖，就需要注射1单位的速效胰岛素，如Apidra、Fiasp、Humalog或Novorapid。 例如，如果某人的血糖水平为15.2 mmol/L，ISF为1:2.0，目标血糖水平为6.5 mmol/L，则需要大约4到4.5单位的速效胰岛素将血糖调整至目标水平。 具体计算方式是：当前血糖水平减去目标血糖水平，然后除以ISF（15.2 - 6.5 …

2021年12月16日 · Mealtime insulin: if carbohydrate counting is accurate, change ICR if glucose after meal consistently out of target. Correction insulin: adjust ISF and/or target glucose if correction does not consistently bring glucose into range. Basal rates: adjust based on overnight, fasting, or daytime glucose outside of activity of URAA/RAA bolus.

2020年9月22日 · Insulin-to-carb ratio (ICR), also known as carb ratio or carb factor, is a calculation used to determine how many grams of carbs are covered by one unit of rapid-acting insulin for a person with diabetes. Determining this ratio ensures that the patient’s glucose levels stay within the target range you have set with them.

Carb Ratio (formerly termed Insulin to Carb Ratio or ICR) A Carb Ratio describes the amount of carbohydrate “covered” by one unit of bolus insulin. For example, a Carb Ratio of 10 means that each 10 g of available carbohydrate consumed (carbohydrate minus fibre) requires 1 …

An insulin sensitivity factor (ISF) or correction factor describes how much one unit of rapid or regular insulin will lower blood glucose. For example: An ISF is used to correct "high" glucose readings. It is individualized and based on total daily dose of …

2017年4月20日 · 大多数胰岛素泵都配有软件来协助计算胰岛素剂量，将病人的 ICR、ISF、葡萄糖和胰岛素目标水平，胰岛素起效时间输入软件来决定输注多少胰岛素。 病人输入计划消耗碳水化合物的克数和当前监测血糖数值，该泵会计算出餐前大剂量。 患者应在分娩前、体育活动前，摄入高热量食物，疾病时对胰岛素泵程序进行修改。 3. 胰岛素泵提供多种胰岛素大剂量形式。 （1）方波大剂量：可以使胰岛素输注扩展到指定时间内，当患者进餐时间过长或吃了高脂肪、高蛋白 …

结论： 使用大剂量向导调整血糖过程中，icr和isf与患者第1天平均血糖、三餐后血糖有关；如果在治疗中不断及时调整icr和isf，可提高向导胰岛素剂量的准确性。
