First Aid, How Cold Is My Theory

- Aug 02, 2018 -

Cold compress is a treatment used in many pre-hospital first aids and is a method that non-medical staff can use. How cold is it to be appropriate?


First, the concept


Cold compress:


The temperature of the object used is lower than the body temperature of the patient at that time, and is close to its body temperature, and has no cold feeling.


Ice:


The object used is at a temperature below 0 ° C or has a cold feel.


Second, the principle


Cold compress:


The relatively high heat of the local tissue is transmitted to the object, causing the tissue temperature to decrease; it is also possible to lower the local blood flow temperature and thereby lower the whole body temperature.


Ice:


The use of low temperature to reduce tissue activity, reduce necrosis, the temperature of the object is below 0 ° C; shrink the blood vessels, reduce blood flow, inhibit bleeding.


Third, examples


Cold compress:


Use heat to reduce body temperature during heat stroke. Heatstroke is a disorder of body temperature caused by various reasons, leading to organ dysfunction and causing various symptoms and reactions. So it should be cold (the principle is as above). Ice application will cause local blood vessels to contract, slow blood flow, and reduce the effect of circulating cooling.


Ice:


In the case of sprain, local capillary breakage leads to internal bleeding, and ice can prevent swelling of blood stasis (the principle is the same as above). The cold compress does not reach the shrinkage effect.


Fourth, the application


Cold compress:


The neck, armpits, and groin of patients with fever and heat stroke. Burning burns, etc.


Ice:


Sprained parts, broken limbs, etc.


Five, tools


Cold compress:


Cold and hot packs, tap water, bottled water at room temperature, etc.


Ice:


Hot and cold ice packs popsicles, etc.
