- 生物医学工程 生物医学工程
背景情况:
- 血液透析 (HD) 患者的风险预测是复杂的,因为流体状况,心脏功能和并发症.
- 评估心脏功能是心血管 (CV) 死亡率的关键预测因素,在常规的HD护理中具有挑战性.
研究的目的:
- 调查一种新型的非侵入性缩功能指数与疾病发病患者死亡率的关联.
- 评估该指数与透析期间体积去除之间的相互作用.
主要方法:
- 对558名HD患者 (平均年龄66岁) 进行24小时门诊血压监测的分析.
- 包括波强度分析,特别是S:D比率 (SDR),作为一个新的指数.
- 利用多变量比例危险模型进行风险预测,以所有原因和心血管死亡率作为终点.
主要成果:
- 在单变量和多变量分析中,SDR与所有原因 (HR 1.36) 和心血管死亡率 (HR 1.41) 显著相关.
- 从透析前到透析后的SDR变化在不同的超过体积组之间有显著差异.

01:19Assessing 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.

The glomerular filtration rate (GFR) is a critical indicator of kidney health, reflecting how well the kidneys filter blood. Changes in GFR can signal potential kidney impairment, necessitating accurate measurement methods to monitor kidney function effectively.Various molecules can serve as markers for GFR measurement, with the ideal marker meeting several specific criteria. It must freely filter at the glomerulus, avoid reabsorption or secretion by the renal tubules, remain unmetabolized, not...
