Insulin Sliding Scale

• Dosing depends on the patient's level of insulin resistance.
• The example sliding scales are for regular insulin with blood glucose (BG) measured in mg/dL

Low Dose (Renal Insufficiency)

• BG 150-199: 1 unit bolus Insulin
• BG 200-249: 2 units bolus Insulin
• BG 250-299: 3 units bolus Insulin
• BG 300-349: 4 units bolus Insulin
• BG Over 350: 5 units bolus Insulin

Medium Dose (Standard)

• BG 150-199: 1 unit bolus Insulin
• BG 200-249: 3 units bolus Insulin
• BG 250-299: 5 units bolus Insulin
• BG 300-349: 7 units bolus Insulin
• BG Over 350: 8 units bolus Insulin

High Dose (Severely Insulin Resistant)

• BG 150-199: 2 unit bolus Insulin
• BG 200-249: 4 units bolus Insulin
• BG 250-299: 7 units bolus Insulin
• BG 300-349: 10 units bolus Insulin
• BG Over 350: 12 units bolus Insulin
