Clinical Evaluation of a Computer-controlled Pressure Support Mode

Clinical evaluation of a computer-controlled pressure support mode.

We have designed a computerized system providing closed-loop control of the level of pressure support ventilation (PSV). The system sets itself at the lowest level of PSV that maintains respiratory rate (RR), tidal volume (VT), and end-tidal CO(2) pressure (PET(CO(2))) within predetermined ranges defining acceptable ventilation (i.e., 12 < RR < 28 cycles/min, VT > 300 ml [> 250 if weight < 55 k...

Computer Support for Pressure Distribution Controlled Shape Design

1 INTRODUCTION Cars and vehicles are typical products that are in daily, direct and constant interaction with domains of the human body when in use. These products are manipulated with the hands or feet (control-arms, pedals), support the body (seats, beds), or provide protecting function (cabins, safety devices). In order to increase the comfort of use, designers should strongly consider ergon...

A clinical decision support system for contact lens evaluation

Background: Contact lenses are transparent, thin plastic disks that cover the surface of the cornea. Appropriate lens prescription should be performed properly by an expert to provide better visual acuity and reduce side effects. The lens administration is a multi-stage, complex and time-consuming process involving many considerations. The purpose of this study was to develop a decision support...

Experimental Evaluation of Batch and Continuous Production of Baker’s Yeast under Computer Controlled pH

Steady state and dynamic fermentations of baker's yeast in molasses based media were analyzed in a laboratory scale bioreactor. Sugar and biomass balances together with the Monod biokinetics were used to develop the process model. Parameters of the model were obtained using collected experimental data. Model predicted open loop responses to step changes in feed concentration as well as dilu...
