ABSTRACTThe purpose of this study was to evaluate the use of a novel health information technology (HIT), a large customizable interactive monitor (LCIM), implemented in a pediatric intensive care unit (PICU). Specifically, we explored nurses’ perceptions of this novel HIT application and its perceived effect on family engagement. We used a qualitative research design to collect and analyze data from 55 PICU nurses in seven focus groups. A trained moderator followed a semi-structured discussion guide with questions related to perceptions, attitudes, and care team interactions with the LCIM. Groups were audio-recorded, transcribed, and coded using content analysis procedure. Six major themes emerged from the nurse focus groups, which include familiarity and use routines, positive perceptions with the LCIM, negative perceptions with the LCIM, privacy, training, and suggestions for improvement. Insights into nurses’ perceptions of the LCIM have the potential to improve family-centered care. 相似文献

In the present work, the effect of some newly synthesized Schiff bases containing sulphur nitrogen as heteroatom was investigated on mild steel corrosion in acidic media. Electrochemical studies of the mild steel samples were performed in an aerated solution of 0.1 M HCl + dimethyl sulphoxide (DMS) as co-solvent. DMS is also behaving as a corrosion inhibitor for mild steel. At low inhibitor concentration and short immersion time one can see only the inhibitive effect of DMS as anodic inhibitor for mild steel. At high concentration and long immersion time inhibition efficiencies are increased and cathodic inhibition is observed. 相似文献

液相停留时间分布分析用于下喷式环流反应器导流筒顶部区域、底部区域、环隙流体流动特性研究。分别将轴向扩散模型应用到各个区域,实验结果表明轴向扩散模型能较好的预测反应器内流体的停留时间分布。采用最小二乘法拟合实验响应曲线,得到模型方程参数。结果表明各个部分的Pe值均随液体喷射速度的增大而减小。导流筒顶部区域的Pe值变化范围为:25.4~6.6;导流筒底部区域的Pe值变化范围为:45.4~11.6;环隙的Pe值变化范围为:60.0~39.2。结果表明导流筒顶部区域返混最大,环隙区域接近于平推流。反应器混和时间随液体喷射速度的增大而减小,变化范围为:88.3~12.5 s。 相似文献

为提高干燥后期干燥速率、降低能耗,提出了两段节流蒸发两段压缩热泵干燥装置的构想。模拟分析了以R134a为热泵工质、采用卧式流化床干燥机时,蒸发器1中工质蒸发温度te1、蒸发器2中工质蒸发温度te2、冷凝温度tc、两股空气质量流量比r(q1/q2)对制热系数COPH、除湿能耗比SMER的影响规律。结果表明:r=1,tc1=75℃,te2=15℃时,te1由15℃提高到25℃,COPH值由2.40提高到2.75,SMER由1.46 kg/(kW·h)提高到1.82 kg/(kW·h);tc1=75℃,te1=25℃,te2=15℃时,r由0.5提高到3.0时,COPH值由2.44提高到2.62,SMER由1.26 kg/(kW·h)提高到1.96 kg/(kW·h);在模拟条件范围内的COPH为2.40-3.01,SMER为0.89~1.96 kg/(kW·h)。 相似文献
