An ironic or non-literal saying of uncertain origin (a dead metaphor ), [ 1 ] "break a leg" is commonly said to actors and musicians before they go on stage to perform or before an audition .
The major tissues affected are nerves and muscles, where irreversible damage starts to occur after 4–6 hours of cessation of blood supply. [4] Skeletal muscle, the major tissue affected, is still relatively resistant to infarction compared to the heart and brain because its ability to rely on anaerobic metabolism by glycogen stored in the cells may supply the muscle tissue long enough for ...
On the other hand, when the symptoms exceed 14 days, [3] it is called critical limb ischemia (CLI). CLI is the end stage of peripheral vascular disease where there is still some collateral circulation (alternate circulation pathways) that bring some blood flow (although inadequate) to the distal parts of the limbs. [2]

Temperature – cool suggest poor circulation, sides should be compared; Pitting edema – should be tested for in dependent locations – dorsum of foot, if present then on the shins. If the patient has been in bed for a longer period of time one should check the sacrum. Capillary refill – should be less than 3 seconds.
Other factors which may point to a diagnosis of critical limb ischemia are a Buerger's angle of less than 20 degrees during Buerger's test, a capillary refill of more than 15 seconds or diminished or absent pulses. [citation needed] Critical limb ischemia is different from acute limb ischemia. Acute limb ischemia is a sudden lack of blood flow ...
The signs and symptoms of ischemia vary, as they can occur anywhere in the body and depend on the degree to which blood flow is interrupted. [4] For example, clinical manifestations of acute limb ischemia (which can be summarized as the "six P's") include pain, pallor, pulseless, paresthesia, paralysis, and poikilothermia.
