temperatures recorded by rectal , deep esophageal , or tympanic membrane sensors provided a reliable index of core temperature ( including brain temperature ) under equilibrium conditions at 42 degrees c , but only esophageal and tympanic sensors could safely be used to monitor the induction phase of hyperthermia and the adjustive changes in body-heat content required to stabilize core temperature during sustained hyperthermia .
