Ventilator alarm fatigue continues to be a serious problem that directly affects patient safety. Frequent ventilator alarms often desensitize health care providers, or the alarms can blend in with other accustomed sounds in the intensive care unit. Ventilator alarms that go unnoticed for extended periods of time often result in permanent patient harm or death. The intensive care unit can be a s...

In this paper, we propose an algorithm that classifies whether a generated cardiac arrhythmia alarm is true or false. The large number of false alarms in intensive care is a severe issue. The noise peaks caused by alarms can be high and in a noisy environment nurses can experience stress and fatigue. In addition, patient safety is compromised because reaction time of the caregivers to true alar...

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...

In Amboseli National Park, Kenya, both superb starlings, Spreo superbus, and vervet monkeys, Cercopithecus aethiops, give acoustically different alarm calls to different classes of predators. The 'raptor alarms' of starlings and vervet monkeys are so called because they are given exclusively to avian species that attack from the air. In contrast, while vervets give 'leopard alarms' to a narrow ...

Invertible authentication techniques have been used in some special applications (such as medical or military) where original data can be recovered after authenticated. In this paper, we combine features (relation of coefficients) in DCT domain with content features (edges or texture) of JPEG image into multi-features, which are useful to authenticating images from both spatial and frequency do...

In this paper, we proposed an algorithm used to improve the performance of the metric-based segmentation techniques, by which the segmentation points are found at maxima of a distance measured between two contiguous windows shifted along the stream of speech features. In our proposed method, the PCA processes are first performed on the speech features to obtain more robust features, and then th...

Sensing the chemical warnings present in the environment is essential for species survival. In mammals, this form of danger communication occurs via the release of natural predator scents that can involuntarily warn the prey or by the production of alarm pheromones by the stressed prey alerting its conspecifics. Although we previously identified the olfactory Grueneberg ganglion as the sensory ...

OBJECTIVE Performance consequences related to integrating an imperfect alert within a complex task domain were examined in two experiments. BACKGROUND Cockpit displays of traffic information (CDTIs) are being designed for use in airplane cockpits as responsibility for safe separation becomes shared between pilots and controllers. Of interest in this work is how characteristics of the alarm sy...

Introduction Chronic abdominal pain (CAP) is one of the most common indications of esophagogastroduodenoscopy (EGD) in the pediatric population. However, there is not enough information about the diagnostic yield of EGD in children with CAP. We aimed to evaluate the diagnostic yield of EGD in children with CAP in the Eastern Black Sea region of Turkey. Material and methods The study included ...
