Which splint is inflatable to create a stiff barrier around an injury?

• A. SAM Splint
• B. Air Splint
• C. Vacuum Splint
• D. Rigid cast

Answer: (B)

Inflatable splints immobilize an injury by forming a stiff barrier through air pressure. When you place an air-filled wrap around a limb and inflate it, the trapped air expands to fill the chambers and presses against the limb and the splint itself, creating a firm, supportive shell that limits movement and protects the area. The Air Splint is designed specifically to be inflated to a controlled pressure, which is why it best fits the description. It can contour to the limb and accommodate swelling while still providing rigid stability. Other options don’t rely on inflation: a SAM Splint is a moldable, semi-rigid device shaped by hand; a Vacuum Splint achieves rigidity by removing air (vacuum) rather than by inflating; and a rigid cast is a fixed, non-inflatable solid. As with any splint, monitor circulation and sensation before and after application to ensure the injury isn’t restricting blood flow.
