Question

How do sequential compression devices promote venous return post-op?

a) By preventing blood clot formation
b) By promoting arterial dilation
c) By increasing capillary permeability
d) By reducing blood viscosity

Answer 1

Sequential compression devices promote venous return post-op by preventing blood clot formation and aiding in blood flow back towards the heart.

Step-by-step explanation:

Sequential compression devices promote venous return post-op by preventing blood clot formation. These devices work by applying intermittent pressure to the patient's limbs, typically the legs, which helps squeeze the veins and promote blood flow back towards the heart. This prevents blood from pooling in the extremities and reduces the risk of deep vein thrombosis (DVT) after surgery.
