OBJECTIVE The study is aimed to develop and assess the quality of an evaluation form used to evaluate the nurse anesthetic trainees' skills in undertaking a pre-use check of an anesthetic machine. MATERIAL AND METHOD An evaluation form comprising 25 items was developed, informed by the guidelines published by national anesthesiologist societies and refined to reflect the anesthetic machine us...

This paper suggests a new model for reliability demonstration of safety-critical systems, based on the TRW Software Reliability Theory. The paper describes the model; the test equipment required and test strategies based on the various constraints occurring during software development. The paper also compares a new testing method, Single Risk Sequential Testing (SRST), with the standard Probabi...

Saturation of peripheral oxygen (SpO2) is one of the most important parameters of vital signs. Pulse oximeter which based on near-infrared spectroscopy is commonly used as a non-invasive method to measure SpO2[1] ,Currently, medical device manufacturers as well as metrology measurement agencies in China usually use pulse oximeter simulator as the commonly accepted functional calibration equipme...

Rio de Janeiro, Brazil. In 2008, he was invited to lead the Dynamic Equipment area of COMPERJ, the biggest petrochemical complex of Brazil, still under construction. He joined Petrobras in 1989, and began working with rotating equipment maintenance. He was transferred to the process area dealing with rotating equipment optimization, operational proceeding improvements, and operator training, mo...

Mainstream database management systems are designed for general use. Various compromises have been done to satisfy the most common users and the largest markets. One application which has been mostly ignored, is the network equipment made for the telco operators. The equipment used in the telco industry has requirements differing from traditional database applications with respect to availabili...

In industries characterized by heavy utilization of equipment and machinery, such as mining, oil & gas, utilities, transportation, adequate stockholding of critical spare parts becomes essential. Insufficient stocks affect overall performance of physical assets, as lack of spares may result in gross penalties, lower availability or increased operational risks. On the other hand, oversized inven...

The competitiveness of manufacturing companies depends on the availability of their production facilities. The equipment of highly integrated production facilities with robust components and surveillance functionality combined with the right service elements contributes significantly towards securing this availability. In this context there exists an urgent need for research to develop methods ...

The active distribution network has been fully developed because it can achieve efficient energy utilization through the effective control of distributed generation, electrical storage, and loads. However, research on reliability operation still stays in medium long-term calculation, without considering influence dynamic equipment characteristics reliability. In order to improve comprehensivene...
