概括
患者的姿势在听觉任务期间对功能近红外光谱 (fNIRS) 测量的影响最小. 然而,倾斜的姿势像福勒一样.
科学领域:
- 神经科学是一个神经科学.
- 生物医学工程 生物医学工程
背景情况:
- 便携式功能近红外光谱 (fNIRS) 系统用于临床环境中的神经监测.
- 患者的姿势可以影响生理和大脑活动,可能会影响fNIRS测量.
- 像Fowler和半Fowler这样的临床姿势对fNIRS数据的影响还未得到充分研究.
研究的目的:
- 调查各种患者姿势对fNIRS数据的影响.
- 检查福勒姿势和半福勒姿势对血液动力学反应和静止状态信号的影响.
主要方法:
- 在一个模拟的手术室中进行了一项研究,使用了五种姿势:站立,坐直,福勒,半福勒和仰卧.
- 血液动力学数据是在静止状态条件下和听觉刺激期间收集的.
- 分析了每个姿势的特征性血液动力反应函数 (HRF) 和静止状态信号幅度.
主要成果:
- 姿势在听觉任务期间对福勒和半福勒姿势的全球HRF振幅没有显著影响.
- 在全球静止状态信号幅度中没有发现与姿势相关的显著差异.
- 在低频率 (f < 0.09 Hz) 的福勒姿势和半福勒姿势之间观察到静止状态信号的统计学上显著差异.
结论:
- 对于听觉任务诱导的fNIRS数据或一般静止状态信号分析,对姿势效应进行复杂的数据处理可能是不必要的.
- 不同的倾斜姿势可以产生不同的结果,突出需要准确的报告.
- 研究人员应该报告坐着收集数据的倾斜角度,以提高可靠性和上下文.

01:03IR Frequency Region: Fingerprint Region
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the C=O, C=N, and C=C occur between 1600–1850 cm−1.

01:30Pulse rhythm
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac muscle...
