What is the most common on:off time ratio used in mechanical compression?

The most common on:off time ratio used in mechanical compression is 3:1. This ratio indicates that for every three minutes of compression (on time), there is one minute of rest (off time). This pattern is effective for promoting venous return, reducing edema, and improving circulation while allowing sufficient recovery time during the off phase.

The 3:1 ratio provides a balance that helps optimize the benefits of the mechanical compression therapy while minimizing the potential for tissue damage or discomfort that might occur with more prolonged compression. It is particularly useful in rehabilitation settings for conditions such as venous insufficiency or after surgical procedures.

In contrast, the other ratios mentioned, such as 1:3, 1:6, and 6:1, are less commonly utilized. A 1:3 ratio would provide excessive rest time that may not be beneficial for the goals of compression therapy, while a 1:6 ratio would place an even greater emphasis on off time, potentially limiting the effectiveness of circulation promotion. The 6:1 ratio would result in prolonged compression that could lead to discomfort or adverse effects due to sustained pressure on the tissues without sufficient off time. Thus, the 3:1 ratio is optimal for achieving the desired therapeutic effects
