What is the shift of intravascular fluid to the interstitial space called?
The shift of intravascular fluid to the interstitial space is called extravasation or leakage. This can occur due to various factors such as inflammation, increased capillary permeability, or imbalance in hydrostatic pressure.
What changes occur in intravascular fluid because of dehydration?
Dehydration leads to a decrease in intravascular fluid volume, causing an increase in blood osmolarity and a decrease in blood pressure. This can lead to symptoms such as thirst, dry mouth, and decreased urine output.
Why would someone need a hypertonic?
A hypertonic is needed when a patient is experiencing brain swelling. This in turn increases the intravascular osmolality and pulls fluid out of the tissues.
The total body water is divided into intracellular and extracellular fluids Plasma is considered?
Plasma is considered part of the extracellular fluid compartment, which also includes fluid within the interstitial spaces, lymph, and cerebrospinal fluid. Extracellular fluid is further classified into intravascular (plasma) and interstitial fluids.
Why and how does the ECF differ from the ICF?
The extracellular fluid (ECF) is found outside the cells and includes the interstitial fluid and intravascular fluid, while the intracellular fluid (ICF) is contained within the cells. ECF is high in sodium and low in potassium, while the ICF is high in potassium and low in sodium. These differences are maintained by the cell membrane through active transport mechanisms, helping to create a concentration gradient that allows for various cellular processes to occur.
Where are Most of the body's fluid is found?
Most of the body's fluid is found inside cells (intracellular fluid) and in the space surrounding cells (extracellular fluid). The extracellular fluid includes the fluid within blood vessels (intravascular) and the fluid in between cells (interstitial fluid).
Urine is from extracellular fluid?
Yes. Urine is intravascular fluid. That said the body can crenate cells to create intravascular fluid from intracellular fluid. This usually is short term but common in chronic dehydration. Elevated K+ in a malnourished person is hallmark of cellular dehydration.
List the fluid compartments that could be defined as extracellular?
Interstitial fluid, plasma, and transcellular fluid.
Is blood plasma extracellular or intracellular?
It is the intravascular fluid part of extracellular fluid (all body fluid outside of cells)

Dehydration leads to a decrease in intravascular fluid volume, causing an increase in blood osmolarity and a decrease in blood pressure. This can lead to symptoms such as thirst, dry mouth, and decreased urine output.
What is the definition of fluid bolus?
A fluid bolus is the rapid administration of IV fluid (ex. normal saline or lactated ringers) given to increase intravascular volume.
Why fascioliasis patients have submandibular edema?
Fasciola is a blood sucking parasite, it sucks 0.5ml blood/fluke/day. During sucking it removes plasma proteins, albumin. This results in fluid balance disturbance. Normally there is a balance between intravascular space and extravascular space. However, when albumin are lost from intravascular space by effect of fasciola, it will become less concentrated where as the fluid content become high. The fluid content become lower in extravascular space or interstitial tissues as compared to intravascular. Therefore, fluid move from intravascularspace to interstitial tissues. Due to gravity oedema occur in the ventral or mandibular area.
Why would someone need a hypertonic?
A hypertonic is needed when a patient is experiencing brain swelling. This in turn increases the intravascular osmolality and pulls fluid out of the tissues.

What is the reason why there is hypoperfusion in acute renal failure?
due to extracellular fluid volume depletion like the case of ascites(loss of intravascular fluid into the extravascular space), renal salt & water wasting states like diarrhea & vomiting
