Question

Quizplus · Accepted Answer

Avoiding a completely dependent position and performing active ROM exercises during the treatment can help promote circulation and prevent excessive edema formation. Increasing the temperature of the whirlpool to the maximum tolerable may increase venous return but can also lead to tissue damage. Letting the hand hang down as much as possible to take advantage of increased hydrostatic pressure can also lead to excessive edema formation. Keeping the limb relatively still may reduce oxygen demand but can also lead to stagnation of blood and fluid in the extremity.
