Limb ischemia due to arterial embolism presents with which classic signs known as the six P's?

Limb ischemia from arterial embolism blocks blood flow suddenly, so tissues become ischemic very quickly and a characteristic pattern emerges. The classic six P signs reflect this rapidly evolving process: pain that is often out of proportion to exam because nerves are starved for oxygen; pallor from loss of arterial color in the limb; pulselessness distal to the blockage due to absent arterial flow; paresthesias from sensory nerve ischemia; paralysis when muscle and nerve injury progresses; and poikilothermia, meaning the limb lies at the ambient temperature because it can no longer regulate its temperature without adequate blood supply. This constellation signals urgent revascularization to limit tissue loss. Other options describe signs more typical of inflammation, infection, or venous issues rather than acute arterial occlusion, so they don’t fit the scenario as well.
