Hertz. Hertz (abbreviated: Hz) is the standard unit of measurement used for measuring frequency. Since frequency is measured in cycles per second, one hertz equals one cycle per second. Hertz is used commonly used to measure wave frequencies, such as sound waves, light waves, and radio waves.
Novolin R should only be mixed as directed by the physician. 1  Novolin R is a short-acting insulin and is often used in combination with intermediate- or long-acting insulins. 2  The order of mixing and brand or model of syringe should be specified by the physician. A U-100 insulin syringe should always be used.
Long-acting insulin: Is absorbed slowly, has a minimal peak effect, and a stable plateau effect that lasts most of the day. Is used to control the blood sugar overnight, while fasting and between meals; Includes: Long acting insulin analogs (Insulin Glargine, Insulin Detemir) which have an onset of insulin effect in 1 1/2-2 hours. The insulin effect plateaus over the next few hours and is followed by a relatively flat duration of action that lasts 12-24 hours for insulin detemir and 24 hours for insulin glargine.
