Class 3 flat-knit custom compression garments are specifically designed for individuals who experience significant lymphatic dysfunction, typically associated with stage 3 lymphedema. This stage is characterized by severe swelling, often accompanied by skin changes and increased risk for infection. The compression provided by Class 3 garments is appropriate to manage this level of edema, as it offers a higher pressure range that can help facilitate lymphatic drainage, reduce swelling, and improve overall function.

Using class 3 garments for individuals at this stage helps in maintaining the fluid balance in the affected limb, providing the necessary support to manage the severity of swelling and to prevent complications that can arise from untreated lymphedema. The flat-knit design allows for a customized fit that can accommodate the unique contours of the limb, ensuring effective compression where it is most needed.

In contrast, options like pediatric lymphedema and patients at risk for lymphedema might require different levels or types of compression that are more suitable for their conditions. Similarly, the reference to an ankle-brachial index (ABI) of ≤ .6 indicates compromised arterial circulation, which would necessitate caution in applying high-compression garments, making it unsuitable for class 3 garments in those patients.
