Study Notes
Hypovolemia vs. Dehydration
- Hypovolemia is a state of decreased blood volume, whereas dehydration is a state of decreased total body water.
Causes of Hypovolemia
- Hypovolemia can be caused by abnormal fluid losses, decreased fluid intake, or third-space fluid shifts.
- Third-space fluid shifts can occur due to inflammation, trauma, or surgery, causing fluid to move from the intravascular space to the interstitial space.
- Abnormal fluid losses can occur due to diarrhea, vomiting, diuretic use, or bleeding.
- Decreased fluid intake can occur due to lack of access to fluids, nausea, or decreased thirst sensation.
Effects of Hypovolemia
- In hypovolemia, serum electrolyte concentrations typically increase due to decreased fluid volume.
- Decreased fluid intake can exacerbate hypovolemia, leading to further decreases in blood volume.
Third-Space Fluid Shifts
- Third-space fluid shifts are characterized by the movement of fluid from the intravascular space to the interstitial space, leading to decreased blood volume.
Hypervolemia
- Hypervolemia refers to a state of increased blood volume.
- The primary cause of hypervolemia is excessive sodium and water retention.
- Hypervolemia can lead to an increase in serum sodium concentration.
Contributing Factors to Hypervolemia
- Contributing factors to hypervolemia include heart failure, liver disease, and kidney disease, which can impair regulatory mechanisms.
- In patients with impaired regulatory mechanisms, excessive sodium and water retention can lead to a serious hypervolemia.
Effects of Hypervolemia
- Hypervolemia is related to fluid accumulation, particularly in the extracellular fluid (ECF) compartment.
- Sodium plays a key role in hypervolemia, as excessive sodium retention can lead to increased fluid retention.
- Hypervolemia can disrupt fluid balance regulation, leading to further complications.
- The ECF compartment is expanded in hypervolemia, leading to increased blood volume.
