背景情况:
- 职业噪音暴露是耳损伤和听力损失的已知原因之一.
- 有证据表明,暴露在噪音中也可能导致前庭功能障碍,特别是影响耳骨器官.
- 噪声对半圆通道 (SCC) 和它们的功能的影响仍然不太清楚.
研究的目的:
- 用视频头脉冲测试 (vHIT) 评估半圆通道 (SCC) 功能,对有和没有职业噪音暴露的人进行测试.
- 为了比较前庭眼反射 (VOR) 在所有SCC平面上的增加,在暴露于噪音和对照组之间.
主要方法:
- 采用了一种准实验性的,跨组设计.
- 该研究包括15名职业噪音暴露者 (≥5年) 和15名无噪音对照者 (30-55岁).
- 视频头脉冲测试 (vHIT) 用于评估所有六个SCC中的VOR增益.
主要成果:
- 与对照组相比,在暴露于噪音的个体的横向SCC中观察到显著减少的VOR增益.

Equipments Used To Measure Blood Pressure
3.4K
Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Assessment of blood pressure in brachial artery(two-step method)
2.1K
Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...

Assessing Blood pressure using a doppler ultrasound
3.0K
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Assessment of the Cardiovascular System IV: Auscultation
2.8K
Cardiac auscultation is a clinical skill used to assess heart function and detect abnormalities. It involves listening to heart sounds at specific anatomical locations through a stethoscope.
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
