When applying sequential compression devices, what is an important step to take before use?

Measuring around the largest part of the thigh is a critical step before using sequential compression devices because this measurement ensures proper fitting of the equipment. A correctly fitted device provides effective compression therapy, which is crucial for preventing venous stasis and reducing the risk of deep vein thrombosis. Improper sizing may lead to inadequate compression or even discomfort for the patient, negating the intended benefits of the device.

While ensuring comfort and proper functioning of the device is important, such as making sure a power outlet is available for electric devices, or using towels or heating pads, these steps do not directly contribute to the efficacy and safety of the sequential compression device itself. Proper sizing based on measurements is fundamental to its successful application.
