Family Perspectives on Continuous Monitor Use in a Children’s Hospital: A Qualitative Study

OBJECTIVES Alarms from continuous cardiorespiratory and pulse oximetry monitors may contribute to parental anxiety and poor sleep during hospitalization, yet families also may find monitoring reassuring. Our objective was to understand how families perceive the utility, benefits, and harms of continuous monitoring. METHODS In this single-center qualitative study, we used semistructured interviews and direct observation. We enrolled families of patients of a variety of ages and clinical diagnoses. We extracted patient demographic information (age, diagnosis) from the health record. Semistructured interviews were recorded and transcribed. Detailed field notes were taken during observations. We used an inductive thematic approach to develop and refine codes that informed the development of themes. RESULTS We recruited 24 families and conducted 23 interviews and 9 observation sessions. Respiratory conditions (eg, bronchiolitis, asthma) were the most common reason for hospitalization. The hospitalized children covered a range of ages: <4 weeks (16%), 4 weeks to 6 months (20%), 7 months to 5 years (44%), and >5 years (20%); 55% had previously been hospitalized. Families expressed varying degrees of understanding the utility of monitors and often conducted their own assessments before notifying staff about alarms. Families expected monitoring, including negative effects like sleep disruption, as part of hospitalization. Families perceived the benefit of monitoring in context of previous hospital experiences, often seeing less benefit and worrying less about alarms in subsequent hospitalizations. CONCLUSIONS Family members continue to find reassurance from cardiorespiratory monitoring despite evidence that it offers limited benefit outside of the ICU setting. Parental perspectives should be addressed in future deimplementation efforts.

Industrial Pollution Monitoring using LABVIEW and Arduino

With the increase in the number of industries in the world today, it is important to keep the our environment healthy and no toxic for living creatures. This project concentrates on designing a pollution monitoring system for industries that would be detecting the toxic gases concentration in the atmosphere that is given out by chemical, paper, ammonia, etc producing industries. The system is designed to continuous monitor theconcentration of gases such as LPG, CO, Sulphur, chlorine etc. and warns if increasing level of toxic level of gases are detected. The values of the concentration of gases are logged into the excel file for future reference and perform analysis to understand the pattern of ejecting gases. This project uses Gas sensors and Arduino for detection and transmission of the data to Lab-VIEWsoftware for further process. Index Terms: Lab view, Gas sensors, monitoring, analysis,safety device

Abstract 13737: Enhanced Prehospital End-Tidal CO2 Monitor Data Analysis for Intubated Severe Traumatic Brain Injury: Striking Findings From the EPIC Study

Background: Studies show that EMS patients are often inadvertently hyperventilated (HV), resulting in hypocapnia. In TBI, HV markedly increases mortality. We evaluated continuous prehospital ETCO2 data in intubated TBI patients. Methods: Analysis of monitor data files (Philips MRx™) from a sample of intubated TBI cases in the EPIC Study (NIH-R01NS071049). Results: Among hundreds of cases, graphical display of continuous ETCO2 from 3 subjects dramatically exemplified commonly-occurring inadvertent HV. Fig 1 shows unrecognized HV lasting nearly 15 min. Fig 2 reveals nearly 14 min of increasing ventilatory rate and progressively worsening hypocapnia. Fig 3 shows nearly 4 min of HV that ends abruptly with clear, sudden recognition and slowing of ventilatory rate that leads to restoration of normal ETCO2 in only a few breaths. The corresponding EMS patient care records (PCR) failed to document the presence, severity, and duration of HV. Conclusions: In a study emphasizing prevention of HV, subsequent evaluation of continuous ETCO2 data revealed many cases of unintentionally rapid manual ventilation and severe hypocapnia, often occurring for long periods. These findings, even in the face of explicit guideline-based training, demonstrate a clear need for routine access to continuous monitor data among intubated patients for quality improvement and in clinical studies. Review of PCRs does not reliably identify mismanagement of ventilation. Furthermore, these findings make it likely that real-time audiovisual feedback technology would improve ventilatory management by alerting providers to unidentified HV that results from the frequent distractions occurring during EMS care.

The ExoClock Project: an open integrated and interactive platform to continuous monitor the targets of the Ariel space mission

<div class="gs"> <div class=""> <div id=":6dj" class="ii gt"> <div id=":6dk" class="a3s aiL "> <div dir="ltr">The ExoClock Project (www.exoclock.space) is an open, integrated, and interactive platform, designed to maintain the ephemerides accuracy of the Ariel targets. Ariel is ESA's medium class space mission prepared for launch in 2028 to study a large number of exoplanets to better understand their nature. ExoClock aims to monitor the Ariel targets and provide transit timings to increase the mission efficiency.  <div>In the project we use all currently available data (literature observations, observations conducted for other purposes, both from ground and space) to make the best use of resources. ExoClock is open to contributions from a variety of audiences — professional, amateur and industry partners — and it aims to continuous monitor the Ariel targets with a verified list of ephemerides. Apart from its role to support Ariel, ExoClock acts as a service by providing the verified ephemerides for further use by the wide exoplanet community.

Moreover, the first results will be presented briefly and finally, strategies and lessons learned from the operation of the project so far will be shared with the community. <div class="yj6qo"> </div> <div class="adL"> </div> </div> </div> <div class="adL"> </div> </div> </div> <div class="hi"> </div> </div> </div>

CONTINUOUS RADON-IN-WATER MONITORING—COMPARISON OF METHODS UNDER LABORATORY CONDITIONS AND RESULTS OF IN SITU MEASUREMENTS

The extraction of dissolved radon from water to gas is the most common way to measure radon concentration in water continuously. The response delay of continuous radon-in-water detection system (continuous monitor + equilibrator) is influenced by the response time of the continuous monitor and a rate of an establishment of equilibrium in the equilibrator (exchanger unit). Two types of equilibrators were used in performed experiments to compare the response time of various detection systems—RAD AQUA that uses water spraying and equilibrator with ACCUREL® PP membrane that enables radon diffusion. Each of these was connected to the continuous monitor RAD7 or RM-3. The response delay after turning on the water flow through the equilibrator was determined. The fastest detection system was RAD7 + RAD AQUA that was subsequently tested during the insitu measurement of thermal water in the healing spa and water sources near Cheb and České Budějovice.

Evaluating Simple Methodology for Piezoelectric Level Sensors Protection

The increasing frequency of extreme storm events has implications for the operation of sewer systems, storm water, flood control monitoring and tide level variations. Accurate and continuous monitor water level monitoring is demanded in different environments. Piezoelectric sensors are widely used for water level monitoring and work submerged in waters subject to the presence of solid particles, biological fouling and saltwater oxidation. This work aimed to develop a simple, low-cost methodology to protect sensors over long-term deployment. The results show that simple actions, costing less than 2 EUR, can protect and extend the lifecycle of equipment worth over 2000 EUR, ensuring continuous monitoring and maintaining quality measurements.

A Low-Cost Continuous Turbidity Monitor

Turbidity describes the cloudiness, or clarity, of a liquid. It is a principal indicator of water quality, sensitive to any suspended solids present. Prior work has identified the lack of low-cost turbidity monitoring as a significant hurdle to overcome to improve water quality in many domains, especially in the developing world. Low-cost hand-held benchtop meters have been proposed. This work adapts and verifies the technology for continuous monitoring. Lab tests show the low-cost continuous monitor can achieve 1 nephelometric turbidity unit (NTU) accuracy in the range 0–100 NTU and costs approximately 64 USD in components to construct. This level of accuracy yields useful and actionable data about water quality and may be sufficient in certain applications where cost is a primary constraint. A 38-day continuous monitoring trial, including a step change in turbidity, showed promising results with a median error of 0.45 and 1.40 NTU for two different monitors. However, some noise was present in the readings resulting in a standard deviation of 1.90 and 6.55 NTU, respectively. The cause was primarily attributed to ambient light and bubbles in the piping. By controlling these noise sources, we believe the low-cost continuous turbidity monitor could be a useful tool in multiple domains.

PRELIMINARY TECHNICAL DISCUSSION ON A NEW RADON AND ITS PROGENY CONTINUOUS MONITOR USING TWO-FILTER METHOD

Focusing on the scalability of Two-Filter Method, we started to develop a monitor for the concentration of radon and its progeny. In this study, we investigated the influence of a high-humidity environment on measuring radon concentration, and the influence of the decay chamber of the monitor on the measurement. In the high-humidity test, the conversion factor of (Bqm−3)/(cpm) tends to raise with increasing humidity. On the measurement of radon progeny, existence of the decay chamber of the monitor makes measurement sensitivity lower under environments of little aerosols. Radon concentration measurement by the developed monitor could be influenced by environmental humidity, and that counting loss could occur due to deposition of radon progeny inside of the decay chamber. Correction relating these would be needed based on the data of calibration tests.
