How wide should an improvised tourniquet band be when using a muslin bandage?

An improvised tourniquet band should be two inches wide when using a muslin bandage. This width is optimal because it provides enough surface area to apply adequate pressure without causing excessive tissue damage or compromising circulation to the distal extremities. A band that is too narrow might not effectively control bleeding and could risk additional injury to the patient.

In emergency situations, it's crucial for a tourniquet to apply sufficient pressure to occlude blood flow effectively at the injury site. A two-inch width strikes a balance between effectiveness and safety, as it minimizes potential complications while ensuring the tourniquet can be tightened enough to stanch severe hemorrhaging. Wider bands, such as three or four inches, may cause unnecessary harm by damaging underlying tissues, whereas a one-inch band may not distribute pressure evenly, increasing the risk of failure to control the bleeding adequately.
