The failure mode and effects analysis (FMEA) is a widely used analytical technique that helps to identify and reduce the risks of failure in a system, component, or process. One important issue of FMEA is the determination of the risk priorities of failure modes. Risk ranking is produced in order to prioritize the focus on each of the failure modes that are identified. In this study, we applied...

evaluation and improvement of drug management process is essential for patient safety. the present study was performed whit the aim of assessing risk of drug management process in women surgery department of qeh using hfmea method in 2013. a mixed method was used to analys failure modes and their effects with hfmea. to classify failure modes; nursing errors in clinical management model, for cla...

failure mode and effects analysis (fmea) is a method based on teamwork to identify potential failures and problems in a system, design, process and service in order to remove them. the important part of this method is determining the risk priorities of failure modes using the risk priority number (rpn). however, this traditional rpn method has several shortcomings. therefore, in this paper we p...

Background: Early nasal continuous positive airway pressure (NCPAP) has emerged as a primary modality of respiratory support for preterm infants withrespiratory distress syndrome (RDS). However, 30%-40% of these newborns need subsequent mechanical ventilation. Nasal intermittent positive pressure ventilation (NIPPV) is a promising alternative to NCPAP, especially in po...
