<prompt> Hyperthermia -Temperature 41.540 with autonomic dysfunctuionNo change in hypothalamic thermostatFailure of thermoregulation  <response>: Ans. is d i.e., Failure of thermoregulationo Hyperthermia is defined as election of core body temperature above the normal diurnal range of 36 to 37.5degC due to failure of thermoregulation at the level of hypothalamus.o Hyperthermia is not synonymous with the more common sign of fever, which is induced by cytokine activation during inflammation, and regulated at the eve of the hypothalamus.o A temperature above 40degC for 104degF is generally considered to be consistent with severe hyperthermia.Temperature Classification Core rectal, esophageal, etc. 35.OdegC95.O0Fo Hypothermiao Normal36.5-37.5nC 97.7-99.5 DFo Fever37.5-38.3degC 99.5-100.9 degFo Hyperthermia37.5-38.3degC 99.5-100.9 degFo Severe Hyperthermia40.0-41,5degC 104.0-106.7 degF Complication of HyperthermiaRespiratoryCardiacHypotensionSeizureRhabdomyolysisAcute kidneyDICHepaticfunctiondysfunction injury injuryo Aspirationo Acute dccompen-o Results from oBronchospasmsated heart failureperipheral o ARDSand myocardialvasodilatation oNoncordiogenicinjurycardiac Pulmonaryedemao ST segmentdysfunction and o Pneumonitischanges sinusvolume depletion o Pulmonarytachyarrhythmias infarction o Pulmonary hemorrhage
