Key result
No single ideal method exists to assess hydration status in critically ill patients, requiring clinicians to integrate clinical examination, laboratory results, and dynamic hemodynamic monitoring tools.
This review outlines the definitions, pathophysiology, and assessment techniques for hypovolaemia in critically ill patients.
Summarizes hypovolaemia assessment for ICU clinicians; leaves open need for prospective validation of techniques.
Assessment of the intravascular volume status of patients is one of the most challenging tasks for the intensive care clinician. It is also one of the most important skills in intensive care management as both hypervolaemia and hypovolaemia lead to increased morbidity and mortality. The assessment of hypovolaemic patients is aided by several clinical signs, laboratory investigations, and a multitude of haemodynamic monitoring systems. This review aims to outline the definitions, pathophysiology, and various assessment techniques (both old and new) employed by intensivists on the critically ill patient.

Mullen et al. (2017) conducted a review in Hypovolaemia in critically ill patients. Assessment techniques for hypovolaemia was evaluated. No single ideal method exists to assess hydration status in critically ill patients, requiring clinicians to integrate clinical examination, laboratory results, and dynamic hemodynamic monitoring tools.
