概括
一种新的常见经神经电刺激器 (CPNES) 有效地改善下肢深静脉血动力学,类似于间歇性气压压缩 (IPC). 这种可穿戴设备可以帮助预防静脉血栓形成,而不会产生不良影响.
科学领域:
- 血管医学 血管医学
- 生物医学工程 生物医学工程
- 生理学 生理学 生理学
背景情况:
- 已知间歇性气压压缩 (IPC) 和神经肌肉电刺激可以增强下肢深静脉血液动力学.
- 一个新的,可穿戴的常见经神经电刺激器 (CPNES) 已开发,以提高便利性和易用性.
研究的目的:
- 评估CPNES干预深静脉血液动力学的有效性和安全性.
- 为了比较CPNES的血液动力学效应与传统的IPC.
主要方法:
- 招募了30名健康志愿者,并随机分成两组 (A和B).
- 组A接收IPC,接下来是CPNES;组B接收的干预是相反的顺序.
- 在每次干预之前和之后,测量了表面大腿动脉和静脉的血液动力学.
主要成果:
- 无论是IPC还是CPNES干预都显著增加了大腿静脉峰值速度,时间平均血流速度 (TAMV) 和流速相比基线 (P < .05).
- 在IPC和CPNES干预之间没有观察到血液动力学参数的显著差异 (P > .05).
- 在任何一组的干预中都没有注意到大腿动脉流速的显著变化.
结论:
- 在改善下肢血液动力学方面,CPNES的有效性与IPC相美.
- CPNES干预增加了血液流动,可能有助于预防静脉血栓形成.
- 据报道,CPNES设备的使用似乎是安全的,没有报告的不良反应.

01:11Pulse Assessment Sites
926
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

01:27Assessment of the Cardiovascular System III: Palpation
190
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
