Orthostatic hypotension is one of several signs and symptoms of hypovolemia. Hypotension is the medical term for low blood pressure. Orthostatic hypotension is when the blood pressure drops as a person stands up from a sitting position (NINDS). Because hypovolemia can cause low blood pressure, orthostatic hypotension is associated with hypovolemia (Schmidt, 2000).
Hypovolemia can interfere with the amount of blood that the heart can pump and deliver to other organs in the body. This means that hypovolemia can cause a number of signs and symptoms related to the heart. One of the signs and symptoms of hypovolemia is tachycardia (Nursing, 2000). Tachycardia is the medical term for rapid heartbeat (Mayo Clinic).
Poor Skin Turgor
Another one of the signs and symptoms of hypovolemia is poor skin turgor (Schmidt, 2000). Poor skin turgor is the skin’s inability to be stretched or moved and then return quickly to normal (University of Maryland Medical Center). Because hypovolemia is associated with fluid depletion, poor skin turgor results from the lack of fluid and the reduced blood volume in the body.
Body temperature is regulated by a number of factors. Changes in perspiration, fluid intake, fluid loss, and related measures can cause the body temperature to rise or fall. Another sign of this condition is a slight increase in body temperature. This can be explained by the fluid imbalance or blood loss that can cause hypovolemia (Schmidt, 2000).
