简要总结
Comparison of a non-invasive method of measuring central venous pressure to the conventional modality of invasive central venous pressure.
详细描述
The conventional method used to measure central venous pressure has limitations since it is an invasive procedure that requires a central venous catheter. To overcome this challenge, a new technology to assess CVP non-invasively using an oscillometric method is being developed. It is called enclosed zone central venous pressure (ezCVP). A comparison study of ezCVP and CVP is needed to determine accuracy and reproducibility.

结局指标
主要结局
Non-invasive pressure indicator
时间窗: 1-7 days
Evaluate sensitivity and specificity of ezCVP indication based on the case where CVP is in a 'low range' (0 \< CVP \< 10 mmHg) or 'high range' (\>= 10 mmHg)
次要结局
- Direction of change(1-7 days)
- Correlation with invasive CVP(1-7 days)
