Abstract

Accurate assessment of a patient’s volume status, as well as fluid responsiveness is a critical task in the care of critically ill patients. Hypovolemia with hypotension and tissue underperfusion are usually more alarming to physicians, but hypervolemia is also associated with poor outcomes, making euvolemia a crucial goal in clinical practice. Nevertheless, the assessment of volume status can be challenging, especially in the absence of a gold standard test that is reliable and easily accessible to assist with clinical decision-making. Therefore, using more than one monitoring technique is important, especially by providing real time and precise measurements of cardiac output. Beside that, physicians need to have a broad knowledge of the strengths and limitations of these tools, these variable. Guided by these variables, the decision to infuse fluid should consider specific triggers, such as signs of tissue hypoperfusion. This comprehensive evaluation of the risk, benefits and efficacy of fluid infusion helps to individualize fluid management, which should be preferred over a fixed restrictive or liberal strategy.
