Providing Safe Gastric Feedings In Pediatric Patients On High Flow Nasal Cannula Respiratory Support
… Unit (PICU). The primary outcome evaluated HFNC flow rates when starting gastric feeds. Secondary outcomes include adverse events (AEs), physiologic distress, and PICU/hospital LOS. Data were analyzed using Chi-Square test with Fisher’s Exact Test for categorical variables and Kruskal Wallis for …

Evaluation of Nutrients and Suspended Solids Removal by Stormwater Control Measures Using High Flow Media
High Flow Media (HFM) is able to treat large runoff volumes using small- footprint systems. Seven full-scale HFM Stormwater Control Measures (SCMs) in a residential area were monitored over 11 months to assess the removal of Total Suspended Solids (TSS), Nitrogen, and Phosphorus in First Flush (FF) …

The design, development, and validation of an accessible high flow nasal oxygen solution with patient scoring outputs
… to healthcare units to treat hypoxemic symptoms. High Flow Nasal Oxygen (HFNO) device are medical oxygen therapy devices, with its use emerging through the COVID-19 pandemic and ongoing to treat congenital diseases, to effectively treat poor patient vitals and oxygenate patients. Clinical settings …

High flow nasal oxygen versus mechanical ventilation as initial respirator support in severe COVID-19 ARDS at Groote Schuur Hospital : a propensity score analysis
… in particular. Due to ICU resource limitations, high flow nasal oxygen (HFNO), a novel ventilation strategy, was implemented as an alternative to mechanical ventilation (MV) at Groote Schuur Hospital in Cape Town, South Africa, during the first COVID wave. Patient received MV if HFNO failed. The …

A review of the use of high flow nasal cannula oxygen therapy in hospitalized children at a regional hospital in the Cape Town Metro, South Africa
Background: High-flow nasal cannula oxygen (HFNC) is a non-invasive alternative to nasal continuous positive pressure oxygen (CPAP) therapy for infants and children requiring respiratory support. There is a paucity of literature to support its use in children, with no published data from …

High flow nasal oxygen in resource constrained, non-intensive care high care wards for COVID-19 acute hypoxaemic respiratory failure: comparing outcomes of first versus third waves
Background: High flow nasal oxygen (HFNO) is an accepted treatment for severe COVID-19 related acute hypoxaemic respiratory failure (AHRF) especially where limited access to intensive care unit (ICU) resources exists, and approximately halves the need for invasive mechanical ventilation. …

Indication for and outcomes of continuous Positive Airways Pressure (CPAP) and High Flow Nasal Cannula oxygen therapy (HFNC) in children admitted to Red Cross War Memorial's Hospital (RCWMCH) excluding those with primary respiratory aetiologies
… Continuous Positive Airway Pressure (nCPAP) and High Flow Nasal Cannula oxygen therapy (HFNC) are non-invasive ventilation (NIV) modalities appropriate for children in developing countries. There is minimal literature describing nCPAP and HFNC use in children with respiratory compromise secondary …

Stream Habitat Characterized by Stage -Specific Flows and Three-Dimensional Geomorphological Complexity: Development of Ecological Criteria for Stream Restoration Design
… geomorphological complexity, and associated flow structures at low- and high-flow stages. In this two-tier classification scheme, the term fluvial habitat unit was used because fluvial refers to both form and flow. At low-flow stages nine habitat units were identified; they included …

LiDAR Assessment of Sediment Transport Related to the Removal of the Marmot Dam, Sandy River, Oregon
… time, and 3) to assess the effect of natural high-flow events on the sediment distribution related to the dam removal. The results showed that a sediment pulse could be identified and tracked up to 13 km downstream from the former dam, but below that the pulse could not be detected from normal …

Design and performance evaluation of a rotary flow control valve for independent metering hydraulics.
… still rare, especially in application requiring high flow rates. Flow control valves are used in flow regulation and controlling of hydraulic actuators’ speed. The speed control occurs through throttling, which causes large power losses. Moreover, the substantial flow forces acting on the …

The performance of certain combined sewer overflows with storage
The provision of storage at overflows is a commonly used technique for the reduction of pollution from combined sewer systems. Field data were gathered at three combined sewer overflow sites during dry weather and a wide range of high flow events. The overflows incorporated off-line storage which …

The Effect of Flow on Burrowing in Juvenile Freshwater Mussels (Bivalvia, Unionidae)
… of juvenile mussels were tested in response to flow and substrate in a recirculating flow tank. Two species were compared: a habitat specialist, Lampsilis reeveiana, and a habitat generalist, Lampsilis siliquoidea. Three flow rates were tested: no flow (zero cm per second), low flow (4.6 cm per …

Estimating Floodplain Vegetative Roughness using Drone-Based Laser Scanning and Structure from Motion Photogrammetry
We compared high-resolution drone laser scanning (DLS) and structure from motion (SfM) photogrammetry-derived vegetation heights at the Virginia Tech StREAM Lab to determine Manning's roughness coefficient. We utilized two calibrated approaches and a calculated approach to estimate roughness from …

Shared Creativity and Flow in Dance Improvisation Practice
… shared creative processes and the role of flow experience in group dance improvisation. A literature review suggested that dancers associate high-quality performance with 'being in the flow', and that group flow is a peak experience when a group is performing at its highest level. The first …

Spatial and Temporal Transitions in the Composition and Transport of Carbon under Variable Flow
… reservoir systems. Impoundments disrupt river flow patterns, as they increase hydraulic residence time and alter the flow of DOM downstream. During storms when the majority of DOM loading occurs, impoundments become less likely to hold DOM and will increase export of DOM downstream. In this …
