概括
肺部超声波得分可以预测在出生时体重非常低的婴儿中,呼吸系统的恶化比需要氧气的时间更早. 这使得在新生儿需要增加吸入氧 (FiO2) 分数的早期干预成为可能.
科学领域:
- 新生儿科学 新生儿科学
- 儿科肺病学 儿科肺病学
- 医疗成像医学成像
背景情况:
- 在妊娠期30周之前出生的婴儿在2周时有增加的氧气需求,其呼吸结果较差.
- 在出生体重非常低的婴儿中,呼吸状况在2周后恶化与更差的预后有关.
研究的目的:
- 根据婴儿的氧气需求,研究肺超声波 (LUS) 得分在非常低出生体重婴儿 (VLBWI) 的演变.
- 为了确定LUS是否能比吸入氧气分数 (FiO2) 的变化更早地检测呼吸系统恶化.
主要方法:
- 在妊娠期30周之前出生的104名新生儿根据最初的FiO2进展被分为三组.
- 肺部超声波 (LUS) 评分是在出生时进行的,生命的3天,1周和2周.
- 统计分析根据第7天的妊娠年龄进行了调整.
主要成果:
- 初始FiO2低的婴儿在出生时LUS得分较低.
- 两周后体验FiO2增加的VLBWI在3天后显示LUS得分上升.
- 在VLBWI中,这种LUS得分的增加是显著的,即使在调整妊娠年龄后也是如此.
结论:
- 肺超声波 (LUS) 评分可以在FiO2增加明显之前识别VLBWI的呼吸系统恶化.
- 与监测氧气需求相比,LUS提供了VLBWI呼吸衰退的早期指标.

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

01:16Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
975
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
