What would 50F Colorado River water immersion do to someone suffering from heat stroke? harmful?
"Heatstroke treatment centers on cooling your body to a normal temperature to prevent or reduce damage to your brain and vital organs.
To do this, your doctor may take these steps:
- Immerse you in cold water. A bath of cold or ice water can quickly lower your temperature.
- Use evaporation cooling techniques. Some doctors prefer to use evaporation instead of immersion to lower your body temperature. In this technique, cool water is misted on your skin while warm air fanned over your body causes the water to evaporate, cooling the skin.
- Pack you with ice and cooling blankets. Another method is to wrap you in a special cooling blanket and apply ice packs to your groin, neck, back and armpits to lower your temperature."
Way too much verbiage by the media is wasted on 'drink water... drink water' when most all of these heat related deaths we read about in Phoenix & GC, etc. are not dehydration but heat stroke . That is, generally speaking, when the body's temperature reaches 104 & above. Obviously drinking fluids will have little to no effect on the deadly symptoms once they have developed. The media spends almost no time on helping folks understand the symptoms of heat stroke and how imperative quick thinking and immediate
application of treatment are to increasing the chances of survival.
Some experts say that heat stroke patients should not drink any fluids until their body temp gets back down to about 100, as one of the symptoms of H.S. can be vomiting .
Not mentioned above by Mayo..... Chilled IV fluids are sometimes administered to aid rapid body cooling with the byproduct of hydration.
