Investigations:With the temperature dropping recently I thought it might be a good time to retweet the first infographic from my #infographic challenge. Hypothermia, the correlation of core temperature and physiological changes. I hope it's useful.

Put the temperature on the gas machine
Look for J waves (osborn). The upward deflection of the terminal S wave (at the junction of the QRS and the ST segment) occurs at or near 32 C. It is first seen in leads II and V6.
Rewarming - consider bypass in cardiac arrest, haemodynamic instability and a core temperature below 32°C, frozen extremities and rhabdomyolysis with hyperkalaemia.
Treat electrolyte disturbances - being careful of hypokalaemia as potassium will increase with re-warming
Remember coagulopathy is common
Haemocrit will rise.
Treat with 40 degrees water, aspirin
In cardiac arrest
Don't give up too soon. Watch this great youtube video. It's true!
