BACKGROUND The OxiMax N-600x containing SatSeconds alarm management software was designed to assist clinicians in discriminating nuisance alarms from those that are clinically relevant. Instead of sounding an alarm the moment the oxygen saturation reading violates the upper or lower limit settings, a magnitude and duration of tolerance can be set. The primary objective was to study the proporti...

Some mammals distinguish between and respond appropriately to the alarm calls of other mammal and bird species. However, the ability of birds to distinguish between mammal alarm calls has not been investigated. Diana monkeys (Cercopithecus diana) produce different alarm calls to two predators: crowned eagles (Stephanoaetus coronatus) and leopards (Panthera pardus). Yellow-casqued hornbills (Cer...

BACKGROUND Clinical alarm systems safety is a national concern, specifically in intensive care units (ICUs) where alarm rates are known to be the highest. Interventional projects that examined the effect of changing default alarm settings on overall alarm rate and on clinicians' attitudes and practices toward clinical alarms and alarm fatigue are scarce. OBJECTIVE To examine if (1) a change i...

Social pollinators such as honey bees face attacks from predators not only at the nest, but also during foraging. Pollinating honey bees can therefore release alarm pheromones that deter conspecifics from visiting dangerous inflorescences. However, the effect of alarm pheromone and its chemical components upon bee avoidance of dangerous food sources remains unclear. We tested the responses of g...

Alarm signalling is of paramount importance to communication in all social insects. In termites, vibroacoustic and chemical alarm signalling are bound to operate synergistically but have never been studied simultaneously in a single species. Here, we inspected the functional significance of both communication channels in Constrictotermes cyphergaster (Termitidae: Nasutitermitinae), confirming t...

This paper, starting from the level of mobile communication network alarm management, comes up with the alarm types and the six-stage model. The paper also discusses the step of recessive maintenance and management from the perspective of mobile communication in terms of the effective control of network alarms, and also extends the network equipment alarm logic correlation to the logical level ...

Background We hypothesized that current vital sign thresholds used in pediatric emergency department (ED) screening tools do not reflect observed vital signs in this population. We analyzed a large multi-centered database to develop heart rate (HR) and respiratory rate centile rankings and z-scores that could be incorporated into electronic health record ED screening tools and we compared our d...

When a chemical plant is abnormal state, an alarm system must provide useful information to operators as the second layer of independent protection layer. Therefore, a method of designing plant alarm system is important for plant safety. Because the plant is modified in the plant lifecycle, the alarm system for the plant should be properly managed through the plant lifecycle. To manage the chan...
