What is an appropriate insulin concentration?
This depends on the infusion device. In general, it is good to be able to adjust the infusion rate by increments of less than 0.1 units per hour for hospitalized adults. We are currently using 0.5 units per cc solution in infusers that are adjustable to the nearest 0.1 cc per hour. This means the infusion can be adjusted by 0.05 unit per hour increments. Higher concentrations can be used in volume critical patients with insulin resistance.
