| Research Abstract |
The operation control of the anesthesia machine is a technology that requires skilling. Besides automatic control, the operation support mechanism is also useful as the technology in the future. We researched the navigator for the operation of anesthesia machine, by which the anesthesia machine for low flow was taken into consideration. We made a theoretical model for the navigator, and researched the user input interface for this navigator.
To construct the model at a practical level, we introduced the following three points for the anesthesia machine. It includes multi-compartments for the anesthesia circuit, an anesthetic absorbing compartment on to the CO_2 absorbent. We connected the models with the body side model by which dead space and pulmonary shunt were considered.
This model was used to analyze behavior of total closed type anesthesia machine, physioflex^<TM>. Moreover, this model was applied to anesthesia gas monitor RAMSCAN (Central uni Co, Tokyo, Japan). And we did the try compared with the model predict value and the measurement value. The concentration in the internal jugular vein was closer to the simulation value in the brain than the measurement of end-tidal anesthetic concentration.
On the other hand, if two general input methods are introduced, it easily satisfies the necessary input items during anesthesia. One is an input method to the event type input having time stamp and an input method of the checklist type without the time stamp. It has been understood that this input method has the high-speed input ability that can be used also for the electronic anesthesia record keeper. Anesthesia simulator program by Symlink^<TM> and input program QA1 by Visual Basic were developed, and the research by which the navigator was made for trial purposes was done.
We keep researching further for the practical use of the anesthetizing navigator.
