Severe Heat Stress Continues in Heatstroke

Splanchnic vasoconstriction will fail
Heated core blood increases ICP
Decreases mean arterial pressure

92

Diagnosis of Heatstroke

Exposure to heat stress
Signs of severe CNS dysfunction
Core temp 105+
Dry, hot skin
Sweating may persist
Marked elevation of liver transaminases

93

3 Ways Heatstroke can Kill
