What does the term "pokilothermia" refer to in the context of arterial occlusion?

The term "pokilothermia," also commonly spelled as "poikilothermia," refers to the body's inability to regulate its temperature, resulting in a reduction in body temperature that aligns with ambient environmental conditions. In the context of arterial occlusion, this phenomenon occurs when blood flow to an area is compromised, leading to decreased perfusion and, subsequently, reduced temperature in the affected tissues.

As blood circulation diminishes due to the occlusion, the impacted region no longer receives warm blood from the core body, causing its temperature to drop toward that of the surrounding environment. This can be a vital sign of ischemia or inadequate blood supply, helping healthcare providers assess the severity of an occlusion. Understanding this term is crucial for critical care paramedics as it informs them about the potential risks and clinical implications of arterial occlusions.
