Study Notes
Hypovolemia and Hypervolemia: Causes, Symptoms, and Treatment
- Hypovolemia leads to shunting blood away from the skin, resulting in cool, pale skin and increased heart rate and blood pressure to compensate for volume loss
- Untreated hypovolemia can progress to sweating, lightheadedness, confusion, fatigue, and decreased blood pressure, potentially causing unconsciousness
- Internal or gastrointestinal bleeding can be a cause of hypovolemia, with symptoms often being the first indications of blood loss
- Fluid shifting out of the bloodstream and severe dehydration can also cause hypovolemia
- Even patients with severe edema may experience hypovolemia if the cardiovascular system does not have enough fluid
- There is no definitive blood test for hypovolemia; vital signs and thorough history and physical exams are used for diagnosis
- Treatment for hypovolemia involves fluid replacement, addressing the underlying cause, and, in severe cases, blood transfusion or intravenous infusion
- Hypervolemia, or fluid overload, is characterized by an increase in total body sodium content and water, often seen in conditions like congestive heart failure, kidney failure, and liver failure
- Causes of hypervolemia include compromised regulatory mechanisms for sodium and water, excessive intake of sodium, and medical conditions like hemodialysis and myocardial infarction
- Symptoms of hypervolemia include rapid weight gain, noticeable swelling, cramping, headache, shortness of breath, high blood pressure, and heart problems
- Causes of hypervolemia include kidney, heart, and liver failure, hormonal changes, and excessive IV fluid intake
- Diuretics and dialysis are common treatments for hypervolemia, aimed at increasing urine production and removing excess fluid from the body
