In my work with wounds, I frequently find the absence of a diagnosis of ischemia, or worse, I find a misdiagnosis. Ischemia is caused by severe obstruction of the arteries, which seriously decreases blood flow. If the arteries are in the heart, you will find a heart attack. If the arteries are in the brain, you will find a stroke. In the skin, you will find a wound.
