Which equipment is commonly used to prevent DVT and peripheral edema in immobile patients?

1. Artificial respirator

2. Sequential compression unit

3. Automated external defibrillator

4. Patient-controlled analgesia pump

The correct answer is: Sequential compression unit

A sequential compression unit is commonly used to prevent deep vein thrombosis (DVT) and peripheral edema in immobile patients. This device helps improve circulation by applying intermittent pneumatic compression to the legs, which can reduce the risk of blood clots forming in the veins and swelling in the extremities. The other options listed are not typically used for preventing DVT or peripheral edema. An artificial respirator is used to assist with breathing, an automated external defibrillator is used to deliver an electric shock to the heart in cases of sudden cardiac arrest, and a patient-controlled analgesia pump is used to administer pain medication.
