What are the 4 body fluid compartments?
The following body fluid compartments are described: total body water (TBW), extracellular fluid (ECF), intracellular fluid (ICF), transcellular fluid TCF), plasma volume, red cell volume and interstitial fluid volume.
What are the 2 major compartments of body fluids?
The body’s fluid separates into two main compartments: Intracellular fluid volume (ICFV) and extracellular fluid volume (ECFV). Of the 42L of water found in the body, two-thirds of it is within the intracellular fluid (ICF) space, which equates to 28L.
What is meant by body fluid compartments?
Total body water can be subdivided into two major compartments, intracellular fluid which is fluid inside cells, and extracellular fluid which is fluid outside of cell like in the blood and in the interstitial tissue between cells.
What is 3rd space fluid?
Third-space fluid shift is the mobilisation of body fluid to a non-contributory space rendering it unavailable to the circulatory system. It is a recurrent clinical phenomenon requiring swift identification to minimise deleterious effects.
What is intracellular and extracellular fluid?
The intracellular fluid is the fluid contained within cells. The extracellular fluid—the fluid outside the cells—is divided into that found within the blood and that found outside the blood; the latter fluid is known as the interstitial fluid.
How are body fluid compartments measured?
To calculate the interstitial (fluid not in the cells and not in the blood) fluid volume, subtract the plasma volume from the extracellular volume. To calculate the intracellular fluid volume subtract the extracellular fluid volume from the total fluid volume.
What is the interstitial fluid?
(IN-ter-STIH-shul FLOO-id) Fluid found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them.
What is the difference between edema and third spacing?
Edema may form which is an abnormal accumulation of fluid in the interstitium; and “third spacing” which refers to an abnormal accumulation of fluid within body tissue or a body cavity may occur. Five types of edema have been identified as a result of impaired balance between fluid compartments.
What is the difference between plasma and interstitial fluid?
The main difference between plasma and interstitial fluid is that plasma contains more proteins whereas interstitial fluid contains fewer proteins. Most of the other dissolved products such as nutrients and electrolytes occur in similar concentrations in both plasma and interstitial fluid.
What is the difference between ECF and interstitial fluid?
The extracellular fluid—the fluid outside the cells—is divided into that found within the blood and that found outside the blood; the latter fluid is known as the interstitial fluid.
What is the 60 40 20 rule for body water?
However, an easier distribution of body fluids to remember is the 60:40:20 rule: 60% of body weight is water, 40% of body weight is ICF, and 20% of body weight is ECF (see Fig. 1-1). Many clinicians use 20% as an estimate for ECF when calculating fluid therapy needs for their patients.
What is body fluid volume?
In lean healthy adult men, the total body water is about 60% (60–67%) of the total body weight; it is usually slightly lower in women (52-55%). The exact percentage of fluid relative to body weight is inversely proportional to the percentage of body fat.
What is the main component of all body fluids?
Water
Water is the main component of all body fluids making up 45-75% of the total body weight.
What are types of fluid?
Fluids are classified into four types depending on its flow, they are:
- Steady or unsteady.
- Compressible or incompressible.
- Viscous or non-viscous.
- Rotational or irrotational.
What is extravascular fluid?
Extravascular fluid. All fluid outside the blood vessels, i.e., intracellular, interstitial, and transcellular fluid’s; it constitutes about 48 to 58% of the body weight.
Is pleural effusion third spacing?
Third spacing In medicine, the term is most commonly used with regard to burns, but also can refer to ascites and pleural effusions.
