Question: 1 / 400

What is the maximum overlap recommended for tourniquet placement?

2 inches

3 inches

The maximum overlap recommended for tourniquet placement is 3 inches. This guideline is based on ensuring adequate compression and effectiveness of the tourniquet while minimizing tissue damage or complications that can arise from excessive pressure. When the overlapped area exceeds this recommendation, there is a risk of compromising blood flow to the underlying tissues, leading to ischemia and potential nerve damage.

Maintaining a 3-inch overlap allows for sufficient containment of the limb without causing unnecessary harm. Tourniquet placement should also consider the anatomy of the area being wrapped and the size of the limb, ensuring that the pressure is evenly distributed. It is essential for healthcare professionals to adhere to these recommendations to promote patient safety and optimal surgical outcomes.
