Although diagnosis will usually be evident after an initial check vital signs, can sometimes missed because overreliance on normal or near-normal oral tympanic thermometer readings.

There are also some known findings associated with hypothermia. For example, produce ECG signs that simulate those acute myocardial ischemia infarction. blunt expected hyperkalemia.
