概括
军事自由落下跳跃没有显示 significant ear barotrauma 在兵中. 这项研究表明,高速下降可能不会导致眼睛巴罗创伤,但建议对更大群体进行进一步研究.
科学领域:
- 航空航天医学 航空航天医学
- 耳鼻喉科 耳鼻喉科 耳鼻喉科
- 运动医学 运动医学
背景情况:
- 军事自由落下涉及从10,000-12,000英尺的快速下降,速度超过193公里/小时.
- 在自由落下时突然的压力变化会导致巴罗创伤,特别是影响充满空气的体腔,如中耳.
- 中耳巴罗创伤是由中耳和周围环境之间的压力差异造成的.
研究的目的:
- 评估在执行军事自由落下的兵中中耳巴罗创伤的发生率.
- 评估与自由落降落跳相关的听觉健康变化.
主要方法:
- 30名兵在自由落下跳跃之前和之后接受了耳内镜和耳 tympanometry.
- 耳内镜检测结果使用修改后的Teed标准 (O'Neill分级系统) 进行分级.
- 斯图尔特-麦克斯韦尔测试被用来统计分析耳内镜发现和耳 tympanogram 曲线的变化.
主要成果:
- 在跳跃前和跳跃后的评估之间,在耳内学发现中没有观察到统计学意义上的变化 (χ2 = 2.000,p = 0.368).
- 在右耳 (χ2 = 3.000,p = 0.558) 和左耳 (χ2 = 2.000,p = 0.736) 的耳曲线变化没有统计学意义.
- 研究人口在跳跃后没有表现出耳部症状或迹象的增加率.
结论:
- 这些发现表明,军事自由落体可能不会显著增加兵眼睛巴罗创伤的风险.
- 建议进行更大规模的队列研究,以全面了解这群人群中眼睛巴罗创伤的患病率和风险因素.
- 这项研究提供了宝贵的洞察力,了解在自由落体作战期间兵的听觉健康状况.

01:05Free-falling Bodies: Example
33.7K
An object falling without any air resistance under the influence of gravitational force is said to be in free-fall. For free-falling bodies, the acceleration due to gravity is constant, irrespective of their mass. Free-fall is experienced not only by objects falling downward, but also by all objects whose motion is influenced by gravitational force alone. The dynamics of free-fall motion can be calculated using kinematic equations of motion, since free-fall acceleration is constant.

01:07Free-falling Bodies: Introduction
14.1K
All objects, neglecting air resistance, fall with the same acceleration towards the Earth's center due to the force exerted by the Earth's gravity. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavier ones. People believed that a heavier object had a greater acceleration when falling until Galileo Galilei (1564–1642) proved otherwise. We now know this is...

1.9K
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
