What condition can result from prolonged use of a tourniquet?

Hemoconcentration occurs when there is an increase in the concentration of cells and solids in the blood, often due to a decrease in plasma volume. Prolonged use of a tourniquet can lead to this condition because the tourniquet restricts blood flow to a specific area, causing the blood to pool. As plasma is forced out of the blood vessels into the surrounding tissues, the concentration of red blood cells, proteins, and other elements within the remaining blood increases.

This can be particularly significant in a healthcare setting when drawing blood, as excessive time with the tourniquet applied can misrepresent results and lead to inaccurate lab values. Therefore, understanding the implications of tourniquet use, including the potential for hemoconcentration, is crucial for medical professionals to ensure accurate diagnoses and treatment plans.
