Use low-reading thermometer
Some standard thermometers record only to 34°C
Measure core temperature with esophageal probe if intubated (most accurate)
Check blood glucose as can be very high in DM or CVA or low when metabolized to keep warm
Potassium >10-12 mEq/L not compatible with life
Coagulopathy:  clotting factor activity and platelet function significantly reduced at temperature < 34°C
Blood is rewarmed for lab testing so results may appear normal
If ABG is rewarmed before analysis, results will be different from patient's actual acid/base state
Refer to therapeutic<unk>  for over and underestimations

Typical sequence is sinus bradycardia → atrial fibrillation with slow ventricular response → ventricular fibrillation → asystole
Other ECG findings:
Osborn (J) wave - Size of wave correlates with degree of<unk> . No prognostic value.
Muscle tremor artifact
T-wave inversions
PR, QRS, QT prolongation
ST segment elevation or depression
AV block
PVCs
