Proper technique is crucial to ensure the effectiveness of leg elevation. Here are some guidelines: 1. Height: Elevate the legs to a level above the heart. This can typically be achieved by using 2-3 pillows. 2. Support: Ensure that the entire leg, from the heel to the knee, is supported to avoid putting unnecessary strain on any part of the leg. 3. Duration: The duration of leg elevation can vary depending on the condition being treated. Generally, intervals of 15-20 minutes multiple times a day are recommended. 4. Comfort: Make sure the patient is comfortable and that there is no pressure on the lower back.
