- 超声波技术的超声波技术
背景情况:
- 肺超声波 (LUS) 中的垂直器件 (VAs) 可以使侵入性机械通风 (IMV) 患者的临床管理复杂化.
- 了解超声波参数对VA产生的影响对于在这个人群中准确解释LUS至关重要.
研究的目的:
- 为了研究特定的超声波设置如何影响肺超声波 (LUS) 检查中观察到的垂直器件 (VA) 的数量.
- 为了确定可调节的LUS参数对VA在入侵性机械通风 (IMV) 患者的存在的影响.
主要方法:
- 肺部超声波 (LUS) 在接受侵入性机械通风 (IMV) 的29名患者身上进行.
- 三位LUS专家评估了VA数量,对每位患者进行了20次随机,盲目的记录,并对每位患者进行了各种超声波设置.
- 统计分析比较了基线和修改的设置之间的VA数量,控制生理和操作因素.
主要成果:
- 基线LUS显示,在3636个专家分类中,吸入时的中位数为2VA,在过期时为1VA.

01:29Mechanical Ventilation I: Indication and Settings
167
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
