conclusions thus, we can conclude that a simulator system using an extracorporeal circulation system can be set to different models of dialyzers, and that the reproduced treatment scenarios can be used for simulation training. results the results of the tests demonstrated successful activation of the alarms by the dialysis apparatus, which were appropriate for each of the five types of accident...

A telecommunication system produces daily a large amount of alarm data which contains hidden valuable information about the system behavior. The knowledge discovered from alarm data can be used in finding problems in networks and possibly in predicting severe faults. In this paper, we devise a solution procedure for mining sequential alarm patterns from the alarm data of a GSM system. First, by...

Alarms in the ICU sound frequently and 85-99% of cases do not require clinical intervention. As alarm frequency increases, clinicians develop ‘alarm fatigue’ resulting in desensitization, missed alarms, and delayed responses. This is dangerous for the patient when an alarm-provoking event requires clinical intervention but is inadvertently missed. Alarm fatigue can also cause clinicians to: set...

background : few studies have focused on syndromic data to determine levels of alarm thresholds to detection of meningitis outbreaks. the purpose of this study was to determine threshold levels of meningitis outbreak in hamadan province, west of iran . methods : data on both confirmed and suspected cases of meningitis (fever and neurological symptom) form 21 march 2010 to 20 march 2012 were use...

Nowadays the organizations are facing the number of threats every day in the form of viruses and attack etc. Since many different mechanisms were preferred by organizations in the form of intrusion detection and prevention system to protect its organizations from these kinds of attacks. Intrusion Detection System (IDS) is considered as a system integrated with intelligent subsystems. In this pa...

This paper proposes a new method to detect correlated alarms and quantify the correlation level to improve the management of industrial alarm systems. The method is mainly composed of three parts. First, a so-called occurrence delay is defined as the main cause leading to erroneous conclusions from existing methods to detect correlated alarms. In order to tolerate the presence of occurrence del...

Sequences of events occur in several applications, such as mobile services (the requests made by each user), telecommunication network alarm handling, user interface studies, etc. Such a sequence can be denoted (〈ei, ti〉), where i = 1, . . . , n, and for each i, ei ∈ E is an event type and ti is the occurrence time. As an example, consider the following excerpt from a sequence of 46662 events (...

BACKGROUND Heart rate (HR) alarms are prevalent in ICU, and these parameters are configurable. Not much is known about nursing behavior associated with tailoring HR alarm parameters to individual patients to reduce clinical alarm fatigue. OBJECTIVES To understand the relationship between heart rate (HR) alarms and adjustments to reduce unnecessary heart rate alarms. METHODS Retrospective, q...

Patient Monitoring Information Systems generate alarms that are designed to make the clinician aware of the condition of a patient, but frequent false alarm occurrence can result in alarm fatigue and reduce the probability of a clinician to respond to the alarms. The purpose of this paper is to develop a simulation model to investigate the effect of false alarms and different alarm routing poli...
