Question

Why can a tourniquet be placed on a leg for hours to prevent bleeding and not induce irreversible cell damage within skeletal muscles, but a few minutes is ischemia within the brain can be deadly?

Expert Solution

Introduction:

A tourniquet is a device that temporarily stops or restricts blood flow to a particular area of the body.
It is frequently employed in healthcare settings to stop bleeding during operations or in emergency situations involving trauma or injury.
Ischemia is a condition in which blood flow to a specific tissue or organ is reduced.
A blood clot, atherosclerosis (the narrowing of the blood vessels), or trauma are just a few of the possible causes.
Ischemia can result in decreased oxygen supply and tissue damage.
