The patient experiences disturbed thermal control because the sympathetic nervous system is damaged.The hypothalamus cannot regulate body heat through vasoconstriction and increased metabolism; therefore,the individual assumes the temperature of the air.
The patient may develop pneumonia,but the temperature fluctuation is due to disturbed thermal control because the sympathetic nervous system is damaged.The hypothalamus cannot regulate body heat through vasoconstriction and increased metabolism; therefore,the individual assumes the temperature of the air.
The patient may have a brain injury,but thermal control is affected because the sympathetic nervous system is damaged.The hypothalamus cannot regulate body heat through vasoconstriction and increased metabolism; therefore,the individual assumes the temperature of the air.
The patient exhibits disturbed thermal control,not because of septicemia,but because the sympathetic nervous system is damaged.The hypothalamus cannot regulate body heat through vasoconstriction and increased metabolism; therefore,the individual assumes the temperature of the air.
