摘要:

Patient electrical isolation is essential during many clinical procedures and investigations. A technique for speeding up a slow nonlinear optical isolator to provide high-speed linear signal transter is described in this paper. The design has proved to be reliable over an extended period in use.

摘要:

The recent focus onproductivityin hospitals due to DRGs, shorter length of patient stays, and lower census has impacted cinical engineering departments. To have an effective and productive clinical engineering program, several organizational and personnel factors should be considered. By integrating these factors with other technical factors, productivity will eventually be improved. Productivity programs, such as Quality Circles, task changes, and shop automation, can have a significant impact on improving productivity. In addition, continued measurement of the effectiveness of the overall clinical engineering department is necessary to determine the effectiveness of productivity improvement programs.

摘要:

QBASE is an integrated patient data manager for tracking and reporting quality assurance (QA) activity in a hospital inpatient setting. The system is written in the KNOWLEDGEMANTM(Micro Data Base Systems) database language and allows on-line storage, inquiry, and reporting functions to support QA procedures. Patient data are entered either at the console or via hand-held portable computers, thus eliminating error-prone transcription procedures. Following the collection of data, QA personnel can edit or delete records, search on various criteria, and generate formatted reports showing individual or departmental exceptions or trends over time.

摘要:

This paper describes the Biomedical Services Department of Deaconess Hospital, which is centrally located in Oklahoma City, OK. The hospital provides family-centered general and acute care with practically all medical specialities represented. The Department consists of one department supervisor, one technician, and one part-time shared-service secretary. The Department is responsible for the repair, safety testing, and calibration of over 600 instruments, and serves an important role in the selection and support of patient care equipment. Training of users is another major role for this department.

摘要:

Pressure losses due to the flow resistance of endotracheal tubes can potentially increase the work of breathing in intubated patients. Previous studies have determined these losses experimentally, but have left some significant questions unanswered. The present study addresses three of these issues: (1) the relationship between tube diameter and flow Reynolds Number for spontaneously breathing patients, which determines whether the flow is expected to be laminar or turbulent(2) a direct comparison of theoretical predictions with measured pressure lossesand (3) a comparison of straight endotracheal tubes with preformed, curved tubes (oral RAE and CAT). Dimensional analysis shows that for tube diameters greater than 3.5 mm, the flow should be predominantly turbulent. Theoretical predictions underestimate actual pressure losses by 30 to 50 percent. Finally, preformed curved tubes (particularly RAE) generate up to 40 percent greater pressure losses in the smaller diameters (less than 5.5 mm) than do straight tubes. This suggests that preformed tubes should be used with caution in spontaneously breathing infants.

摘要:

As Part V of the Journal's series on Bioengineering Education in the U.S., this paper describes college-level programs in the states of Connecticut, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont. Each program is concerned with the broad areas of science and engineering that work together to solve medical problems. The purpose of this series is not to evaluate each program, but to illustrate the breadth of Bioengineering and related programs available today.
