Expert PID control system for blood glucose control in critically ill patients
An expert proportional-integral-derivative (PID) control system for blood glucose regulation in patients, such as the intensive care population, is described, which is sensitive to sensor reading artefact, particularly in the lower ranges of blood glucose level, mandating manual intervention.

Closed-loop Control of Blood Glucose Levels in Critically Ill Patients
It is concluded that closed-loop BSL control using a sliding scale algorithm is feasible, and the main deficiency in the current system is unreliability of the subcutaneous glucose sensor when used in this setting. Expand
A closed-loop system for controlling blood oxygen and carbon dioxide levels in mechanically ventilated patients
Abstract A closed-loop system that regulates arterial O 2 and CO 2 tensions has been presented. While maintaining acceptable blood gas levels, the system attempts to direct a patient from total orExpand
Simulation study on automatic blood glucose control
It is concluded that mathematical modelling of glucose-insulin interaction is a useful tool in testing the functionality of control algorithms prior to in vivo testing. Expand
Automatic Control of Arterial Carbon Dioxide Tension in Mechanically Ventilated Patients
Controlling the arterial carbon dioxide tension of patients receiving mechanical ventilation is achieved by regulating the ventilator initiated breath frequency and also volume per breath. Expand
Optimal H/sup /spl infin// insulin injection control for blood glucose regulation in diabetic patients
The theory of H/sup /spl infin// optimal control has the feature of minimizing the worst-case gain of an unknown disturbance input and can be used to design a "switching" controller that can be applied to insulin injection for blood glucose regulation. Expand
The use of MiniMed CGMS in real-time glucose monitoring
A calibration technique suitable for use in estimating BSL in real-time is needed to make CGMS useful in clinical situations. Expand

An algorithm that estimates the patient and ventilator work components of mechanically ventilated pa- tients is presented. The algorithm requires the continuous measurement of inspiratory airflowExpand
On-line estimation of patient and ventilator respiratory work
The algorithm requires the continuous measurement of inspiratory airflow rate and mouth pressure and it is suitable to be incorporated in ventilators for on-line estimation of the patient and ventilator contributions to the total work of breathing. Expand
