Method of scheduling drug administration using a pulse-oximetry integrated intravenous fluid system comprising retrieving from at least one network server database via an intravenous pump unit patient-related and drug-related data and information. The retrieved data are displayed on the intravenous pump unit interface and then a patient's pulse oximetry data is acquired. Using the pulse oximetry data, patient history, patient condition, diagnosis, and information relating to the one or more drugs, a medical personnel determines a schedule of drug administration. During the set duration of a drug administration schedule, one or more observed effects of the one or more drugs administered to the patient via the intravenous pump unit interface is inputted into the IV pump unit, and the patient record stored in the at least one network database is updated.
