What is the difference between bolus and basal insulin?

Bolus insulin is the quick-acting delivery that you often take before mealtimes. Basal insulin is longer-acting and helps keep your glucose levels steady day and night. Generally, your total daily dosage of injected insulin is split between these short- and longer-acting kinds.

How do you calculate bolus infusion rate?

If you simply need to figure out the mL per hour to infuse, take the total volume in mL, divided by the total time in hours, to equal the mL per hour. For example, if you have 1,000 mL NS to infuse over 8 hours, take 1,000 divided by 8, to equal 125 mL/hr. To calculate the drops per minute, the drop factor is needed.
