These signals must be of an impulsive type, and they can be highly nonstationary. Two main parts exist in the proposed method: first, segmentation of the several tracks constituting the signal, and second, classification of the results of this segmentation. All these processings are automatic and do not need any prior statistical knowledge of the signal. The first field of application for this method is the study of esophageal peristalsis.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

This crisis is a result of using the waterfall paradigm, which neglects many dimensions of system design. The EOP paradigm is based on the multidimensional, multiview, multilingual, and user-oriented (M/sup 3/UO) framework. A CASE tool called the extended operational approach (EOA), developed to support EOP, is presented. EOA is based on JSP, SML, and spreadsheet software. EOP was successfully used in the development of a medical decision and information support system. Experience with using EOA has shown that it reduces the complexity of the specification. The semantic gap between users and development groups, and the effort results in increased productivity, user satisfaction, and more reliable systems.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

In the 1940s and somewhat into the 1950s, technology did not have a tremendous impact on the cost of delivering health care. During the 1960s technology surged ahead, propelled by a great deal of grant monies, which continued to be readily obtainable into the 1970s. However, toward the middle-to-late portion of the 1970s and early 1980s this seemingly unlimited resource for funding came to an end. Insurance companies needed to change their methods of assessment of risk, and the medical profession was forced to change its methods of practicing medicine. These factors combined to contribute to the current climate, especially as it relates to the state of claims processing and reimbursement for health care technology. What the 1990s will bring, while not obvious, is still predictable based on history.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

The PDMS acquires real-time patient data from a network of physiological bedside monitors and facilitates the review and interpretation of this data by presenting it as graphical trends, charts, and plots on a color video display. A patient data simulator was developed for the purpose of complete testing of the PDMS. The simulator also allows for training the medical staff independently of hospital facilities and at a remote location from the ICU. This work outlines the design and functionality of the simulator and focuses on its implementation using OS/2's presentation manager window environment. Some experimental results and performance evaluations are presented, along with areas of future development and use.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

A complex eigenvector-based method for performing spectral analysis of time-domain data independent of the signal-to-noise ratio is demonstrated. The implementation of the procedure requires no preprocessing of the time-domain data record. The technique is well suited for magnetic resonance spectroscopy and imaging, where the signal available from small regions corresponding to areas of diseased tissue in patients presenting for diagnosis is always dominated by the Johnson noise present in the receiver circuit.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

Coherent averaging techniques were developed to determine whether further enhancement of the impedance cardiogram could be obtained. Physiological signals were obtained from 16 male and female subjects during resting conditions, while delivering a speech, and while undergoing submaximal bicycle exercise. Results indicated that improved resolution of dZ/dt signal events could be obtained using coherent ensemble averaging. Although some improvement in precision of event location was obtained, most enhancement of the impedance cardiogram occurred in measurement of the amplitude of the dZ/dt maximum (ejection velocity) during speaking and exercise conditions. Validated increases in dZ/dt maximum exceeding 20% were obtained in some subjects with coherent averaging, suggesting that the diagnostic utility of impedance cardiography can be improved using this technique.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.

Some of the important features of the application are: it is focused on the concept of remote patient care; telecommunication connection is the key link; voice/image/data capability is inherent; flexibility of the circuit switched connection is vital; and portability of equipment to any ISDN port is very important. The application is practical due to the benefits provided by the new ISDN telecommunication service and can be applied to the home environment. The application holds the potential to offer health services to remote locations and to offer care to those in less critical medical conditions, while lessening the demands on in-patient care. It will also, hopefully, help to control costs.<<ETX>>","PeriodicalId":365366,"journal":{"name":"[1990] Proceedings.
