Regulation of Stroke Volume01:27

Regulation of Stroke Volume

3.2K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

914
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

  • 脑卒中医学 脑卒中医学
  • 关键的护理关键的护理

背景情况:

  • 昏迷,一种意识受损的状态,在缺血性中风中没有很好的特征.
  • 大血管闭塞 (LVO) 卒中需要及时诊断和治疗.
  • 在LVO中风中昏迷的表现尚未得到充分研究.

研究的目的:

  • 为了确定LVO中风患者昏迷的发病率和临床特征.
  • 为了调查与LVO中风中昏迷相关的结果.

主要方法:

  • 从2018年7月到2020年12月,对LVO中风患者的回顾性鉴定.
  • 昏迷症被定义为NIHSS项目1a的3分.
  • 对闭塞位置,治疗方法和患者结果的分析.

主要成果:

  • 4.4%的LVO中风患者出现了昏迷状态 (28/637).
  • 昏迷患者的NIHSS得分明显更高 (中位数为32比11).
  • 昏迷独立地增加了舒适护理的几率 (aOR 6.75),并降低了90天良好功能结果的几率 (aOR 0.12).

结论:

  • 昏迷是LVO中风的一个显著表现,发生在前后循环封闭中.
  • 昏迷患者中LVO的延迟识别有助于结果差.
  • 高度怀疑和早期诊断对于改善LVO中风患者昏迷的护理至关重要.
