简要总结
The assessment of intravascular fluid volume status in patients admitted to ICU is essential,not only for diagnosis and treatment but also to improve patient’s monitoring. Although clinical examination and other static(CVP, pulmonary artery wedge pressure,stroke volume) as well as dynamic measures (stroke volume variation, pulse pressure variation) are used but USG is convenient, safe,non invasive,economical, easily obtainable, performed at bedside and encouraging results have been observed with USG based parameters used for CVP estimation. So we intend to do ultrasonographic measurements of IJV and subclavian vein to observe fluid volume status and respiropha variations in ICU patients.
