概括
这项研究使用视频电脑学和功能近红外光谱学监测了状态 (SE) 的重症患者的脑血液动力学. 研究结果表明,在长时间的发作中,神经血管合中断更常见.
科学领域:
- 神经科学是一个神经科学.
- 关键护理医学 关键护理医学
- 生物医学工程 生物医学工程
背景情况:
- 状态 (SE) 可以导致大脑损伤,但其潜在机制尚未完全理解.
- 在SE重病患者中监测大脑血液动力学是具有挑战性的.
- 在发作期间需要使用非侵入性技术来评估神经血管功能.
研究的目的:
- 为了研究神经血管合和脑血管变化在严重病情的成年人中在电图SE期间.
- 使用功能近红外光谱学 (fNIRS) 结合视频脑电图 (vEEG) 进行持续监测.
- 分析与发作特征相关的血液动力学反应.
主要方法:
- 同时对11名重症成人患者进行了vEEG-fNIRS监测.
- 分析了7名电图SE患者的数据.
- 一般线性模型和线性混合效应模型被用来分析血液动力学反应及其与特征的相关性.
主要成果:
- 超过200个小时的监测和1000次扣押被记录.

01:24Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
01:24Bode Plots Construction
The Bode plot is an essential tool in control system analysis, mapping the frequency response of a system through a magnitude plot and a phase plot, both against a logarithmic frequency axis. To construct a Bode plot, consider the transfer function H(ω):
01:30The Electrical Double Layer
In the region where two bulk phases meet, an intricate electric charge distribution arises due to charge transfer, ion adsorption, molecular orientation, and charge distortion. This complex distribution is commonly referred to as the electrical double layer.When a solid electrode interfaces with ions in an electrolyte solution, the speed of electron transfer dictates the rates of oxidation and reduction. The electrode acquires a charge through the escape of atoms into the solution as cations or...
