FIGURE 90.7 Swollen fingers of a child with cold exposure TABLE 90.6 EFFECT OF BODY TEMPERATURE ON ARTERIAL BLOOD GASES MEASURED AT 37°C (98.6°F) pH Paco2 (mm Hg) For each elevation of °C −0.015 +4.4% For each depression of °C +0.015 −4.4% Pao2 (mm Hg) +7.2% −7.2% Management and Diagnostic Studies Therapy for hypothermia can be divided into two parts: general supportive measures and specific rewarming techniques ( Table 90.7 ) Once hypothermia is diagnosed, temperature must be monitored continuously as treatment progresses Defibrillation is less effective when body temperature is below 30°C (86°F), and
