Purpose and Overview
The TERUFUSION Syringe Pump Type SS3 OTCI is intended for the infusion of general and local anesthetics, vasodilators,
cardiotonics, parenteral feeding, anti-cancer drugs, labor-inducing drugs and blood transfusion at ICU, CCU, NICU, operating
rooms or general wards.
This equipment is intended to be used to inject a drug solution from a syringe constantly at a preset hourly flow rate.
Additionally, this product can be used in the TCI mode, which is equipped with predictive models of the drug action (PK/PD) with
three compartments.
* PK/PD Theory: To analyze the drug action by pharmacokinetics (PK) and/or pharmacodynamics (PD).

How the pump works in the TCI mode
In the TCI (Target Controlled Infusion) mode, the pump calculates and controls the flow rate to achieve and maintain the
predetermined (“target”) drug concentration in a patient’s body based on a mathematical model, called a compartment model,
which simulates drug absorption, distribution, and clearance (pharmacokinetics) and the drug effect on the site of action
(pharmacodynamics) in the human body.
This product analyzes the drug action by using the PK/PD models based on a three-compartment model as shown below:

This product provides five TCI modes in combinations of drugs (Propofol and Remifentanil), PK/PD models (Marsh, Schnider, and
Minto), and targets (plasma targeting and effect-site targeting).
