Hypothermia
Etiology
Hypothermia results when body heat loss exceeds body heat production. Hypothermia is most common during cold weather or immersion in cold water, but can occur in warm climates when people lie immobile on a cool surface or after very prolonged immersion in swimming temperature water. wet clothing and wind increase the risk of hypothermia.
Clinical signs
& symptoms
-
-
-
-
-
-
lethargy and clumsiness followed by confusion, irritability, hallucinations, and coma
-
Diagnostic
Test
-
-
CBC
Electrolytes: K+ critical, glucose to rule out hypoglycemia, BUN and creatinine to assess renal function, creatine phosphokinase to assess for diffuse cellular injury, coagulation panel, blood alcohol and drug screen.

Respiratory
Management
-
recognize that the oxyhemoglobin curve is shifted to the left, increasing the affinity of hemoglobin for O2 and thus impairing tissue oxygen extraction.
-
Pathophysiology
Hypothermia slows all physiologic functions, including cardiovascular and respiratory systems, nerve conduction, mental acuity, neruo-muscular reaction time, and metabolic rate.
