👉 The fluid, often referred to as the calculated fluid or calculated total volume of fluid (CTVF), is a critical parameter in various engineering and medical applications, particularly in the assessment of cardiovascular health. It represents the combined volume of blood and interstitial fluid in the body, providing a comprehensive measure of the total fluid content. This calculation is typically derived from blood pressure measurements and body weight, using formulas such as the Goldmann or Bernoulli methods. The fluid content is crucial for understanding conditions like edema, where excess fluid accumulates in tissues, or for assessing the efficiency of fluid balance in patients with heart failure. By quantifying this fluid, healthcare professionals can better diagnose and manage various physiological and pathological states affecting fluid homeostasis.
