摘要:

A uniquedisposable invasive hemodynamic blood pressure transducer systemhas been developed. The system consists of a disposable piezoresistive flow-through transducer with twelve-inch pigtail, a reusable extension cable, an electronic interface module and a custom interconnect cable to attach to most monitors. The transducer has Linden Luer fittings and replaces the dome and reusable transducer in monitoring systems. The cost of the transducer is kept low so that it can be disposable through efficient modern, high-volume semiconductor technology and the fact that additional electrical isolation is accomplished in the interface module. Besides providing electrical isolation, theinterface moduleprovides a universal output which will accomodate all common AC, DC, and pulsed excitation signals from monitors.

摘要:

Experience gained during clinical trials atJohns Hopkins University Hospitalhas led to refinements in a commercialarrhythmia monitoring system. The performance capabilities and limitations are described for normal Coronary Care Unit use. The system evaluation spanned a time period of over 16 months and included 3,176 monitored patient days. The majority of both false and true arrhythmia alarms was found to be produced by two small, statistically independent segments of the patient population.

摘要:

This paper describes a biomedical work-flow management system which is based on aDaily Grand Rounds Method. It was developed and implemented atSt. Marys Hospital Medical Centerin Madison, Wisconsin, to increase the speed, safety and accuracy of biomedical repair, and to reduce the cost of the total biomedical operation.

摘要:

Despite advances in the medical care of critically-ill newborn infants, chronic complications due to intense ventilatory support are common. Selection of ventilator settings is empirical, sincemeasurement of pulmonary functions in newborn infantsis not commonly performed. A microprocessor-based instrument was constructed to measure pulmonary function in critically-ill newborn infants with respiratory failure. Data collected fail to demonstrate any beneficial effect upon pulmonary mechanics with increasing amounts of continuous distending airway pressure, and in fact demonstrate an adverse effect upon the lung ventilation. These results demonstrate the need to measure pulmonary function to develop procedures to select optimum ventilator settings. A microprocessor-based system is suitable for such an application, and could be incorporated into future infant respiratory support equipment.

摘要:

The provision of automatic alarm systems on medical equipment is generally designed to supplement the user's ability to monitor a variety of device and patient variables simultaneously. The potential value of such systems in improving the safety and efficacy of medical care is accompanied by the potential for false reliance on or other misuse of the alarm systems. Therefore the alarm provisions become an important aspect of clinical engineering assessment of equipment with respect to selection, user training, hazard analysis, and the provision of effective and appropriate preventive maintenance programs.

摘要:

The principles and different types of commercially available computerized ventricular arrhythmia detection algorithms are reviewed. Algorithms use either thefeature extraction methodor thecross correlation method. There are advantages and disadvantages to each method. The trend is to use some aspects of both methods. TheAmerican Hospital Associationdatabase may radically change the marketplace. Whether or not a system is successful in a clinical setting is dependent upon many factors including 1) whether the nurses believed that they were part of the decision process; 2) the human engineering for ease of everyday use; 3) the extent and type of in-service education; and 4) the number of false-positives and false-negatives called by the algorithm.
