概括

磁盘双平面方法 (MOD) 是评估新生儿左心房体积 (LAV) 的最可靠的心声回声技术. 虽然可行,但LAAo比率显示新生儿重症监护中的LAV测量的观察者间可靠性较差.

科学领域:

新生儿心脏病学新生儿心脏病学
心声回声扫描 (Echocardiography) 是一种心声回声扫描.
心血管风险评估心血管风险评估

背景情况:

左心房体积 (LAV) 是一个重要的心血管风险标志物.
对LAV的标准心声回声学方法包括面积长度 (AL) 和磁盘方法 (MOD).
新生儿LAV评估通常使用LA到大动脉 (LAAo) M模式比率.

研究的目的:

评估不同心声回声学方法在新生儿中测量LAV的可行性和可靠性.
将AL和MOD方法的准确性与新生儿实践中的传统LAAo比率进行比较.

主要方法:

从新生儿重症监护病人的心声回顾分析.
通过图像质量评分 (发声,缩短,墙壁清晰度) 评估可行性.
使用布兰德-阿尔特曼和相关性分析评估观察者内部和观察者之间的可变性可靠性.

主要成果:

在104名婴儿中,LAAo,AL和MOD方法的可行性是可比的 (中位图像得分为4/6).
在AL和MOD之间有很好的线性回归 (R2=0.99).
LAAo与MOD的相关性很差 (R2=0.28),置信区间很宽.

结论:

所有方法都显示出相同的可行性和观察者内部可靠性.
对LAAo的观察者间可靠性很差,但对AL和MOD方法的可靠性很高.
双飞机MOD推用于新生儿诊疗,因为其可靠性更高;单飞机MOD是一个可行的替代方案.

Respiratory Volumes

Respiratory Volumes

Respiratory volumes are crucial metrics, meticulously measured to quantify the air exchanged in and out of the lungs during various phases of the breathing cycle. These precise measurements are vital for assessing lung function, diagnosing respiratory conditions, and monitoring overall respiratory health. Each parameter provides specific insights into the mechanics of breathing and the functional capacity of the lungs.
Tidal Volume (TV) Tidal volume (TV) is the air inhaled or exhaled in a...

Respiratory Volumes and Capacities

Respiratory Volumes and Capacities

The respiratory system is responsible for the intake of oxygen and the expulsion of carbon dioxide from the body. Respiratory volumes describe the volume of air in the lungs at different phases of the respiratory cycle. Tidal volume is the air breathed in and out during normal, quiet breathing. Inspiratory reserve volume is the air that can be forcefully inspired beyond the tidal volume. In contrast, expiratory reserve volume refers to the air that can be expelled from the lungs after a normal...
