Which of the following methods are recommended to help prevent a pulmonary embolism after sedation?

• A. Sequential compression stockings
• B. A pump blows air into these stockings which gently massages the leg and moves the blood toward the heart
• C. Perform a periodic leg massage while raising the leg above the heart
• D. All of the above

Answer: (D)

Preventing pulmonary embolism after sedation centers on keeping blood moving in the legs to prevent clot formation. Sequential compression stockings apply external pressure to the calves and ankles, which reduces venous stasis and helps push blood toward the heart. Intermittent pneumatic compression devices work similarly, using a pump to inflate cuffs in sequence so the leg muscle pump is effectively simulated, further promoting venous return. Gentle, periodic massage of the legs with the leg raised uses gravity and muscular stimulation to enhance venous flow as well. When used together, these mechanical measures provide a multifaceted approach to lowering the risk of deep vein thrombosis and, consequently, pulmonary embolism in patients who are immobile or recovering from sedation.
