1. Select the Appropriate Size: Choose a splint that fits the child's limb size. 2. Position the Limb: Place the injured limb in a comfortable and anatomically correct position. 3. Slide the Splint Over the Limb: Gently slide the deflated splint over the limb. 4. Inflate the Splint: Use a manual or automatic pump to inflate the splint until it is firm but not overly tight. 5. Check for Comfort and Circulation: Ensure the child is comfortable and check for adequate circulation by monitoring the color and temperature of the fingers or toes.
