Traditionally, most anesthetics have been vapor-phase, such as isoflurane. In recent years there has been a move toward the intravenous (IV) delivery of drugs for anesthesia. One of the more popular IV anesthetics is propofol. For a particular population of subjects, the following kinetic values have been determined: k10 = 0.152, k12 = 0.207, k13 = 0.040, k21 = 0.092, and k31 = 0.0048, all with units of min-1. Also, assume that the volume of the blood plasma compartment is V1 = 12 liters.
