Which assessment finding may indicate impaired tissue perfusion?

Impaired tissue perfusion refers to the inadequate supply of blood to tissues, which can result in a variety of clinical manifestations. A cool skin temperature can be a significant indicator of reduced blood flow and oxygenation to the skin. When tissue perfusion is compromised, the body may redirect blood flow away from the extremities to vital organs, leading to cooler skin as a result of inadequate circulation.

A warm skin temperature typically suggests adequate blood flow and potentially excess heat, which is not indicative of impaired perfusion. Active capillary refill, in contrast, indicates that blood flow is sufficient, as this test assesses the ability of blood to return to the capillaries after they have been compressed. Bright red skin color can be associated with sufficient blood flow and oxygenation, as it often reflects good perfusion rather than impairment.

Therefore, the assessment finding of a cool skin temperature is most directly associated with impaired tissue perfusion, as it suggests that the affected area is not receiving adequate blood supply.
