What is a key contraindication to IPC (intermittent pneumatic compression)?

• A. Acute DVT or significant vascular insufficiency
• B. Chronic back pain
• C. Skin irritation
• D. Age over 70

Answer: (A)

Intermittent pneumatic compression works by periodically squeezing the limb to boost venous return, so applying it when there’s an acute clot or severely impaired blood flow can be dangerous. An acute deep vein thrombosis or significant vascular insufficiency means the limb already has a clot or critically reduced arterial inflow; external compression could dislodge the clot and cause a pulmonary embolism, or worsen ischemia in the limb. That is why this scenario is the key contraindication. Other options don’t pose the same clear, immediate risk: chronic back pain isn’t related to limb perfusion, skin irritation is a local issue that may require adjustment but isn’t an absolute barrier, and age by itself isn’t a contraindication.
