在非通讯患者中检测意识是具有挑战性的. 新的心跳唤起反应 (HER) 标志物,结合心率变化,显示出对意识水平的床边诊断的希望.
科学领域:
- 神经科学是一个神经科学.
- 临床神经学 临床神经学
- 生物医学工程 生物医学工程
背景情况:
- 在非通讯患者中检测剩余意识是很困难的,因为意识并不总是与可观测的行为相关联.
- 基于脑电图 (EEG) 的床边方法为评估意识提供了具有成本效益的替代方案.
- 心跳引起的反应 (HERs) 显示出在识别最小意识和使用机器学习区分其子类型方面的潜力.
研究的目的:
- 探索 HER 中的新型标记物,以表征神经对心跳的反应.
- 确定 HER 的维度是否提供了超越标准事件相关潜在分析的补充信息.
- 调查这些标记在分化意识状态中的有用性.
主要方法:
- 在六组参与者中评估了HER和非心跳锁定EEG:健康,锁定综合征,最小意识状态,植物状态/不响应的清醒综合征,昏迷状态和脑死亡.
- 从 HERs 计算出各种标记,以区分有意识状态和无意识状态.
- 分析了HER变异和前额分离,以及心率变化.
主要成果:
- 发现特定的HERs标记物,包括变异和正面分离,在有意识的个体中较高.
- 这些HERs指数,当与心率波动相结合时,改善了意识水平的差异化.
- 这些发现表明,HERs可以区分有意识和无意识状态.
结论:
- 对脑心相互作用的多维评估,利用 HERs 标记物和心率变异性,可以增强意识障碍的特征.
- 这些发现支持将脑心通信标记物纳入床边诊断电池.
- 对脑心相互作用标记物的进一步研究可能会导致更可行的临床方法来检测意识.

Assessment of apical pulse
Assessing the apical pulse is a critical nursing procedure, particularly indicated for:
Pulse rhythm
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
Pre-Procedural Preparation
Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Assessment of the Cardiovascular System I: Subjective Data
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...
